What is Windows ReadyBoost and does it improve performance?

May 23, 2008 3:26AM PDT
Question:

Hi, I recently bought a new laptop with Windows Vista and I would like to improve the speed of it. Some one mentioned to me that using Windows ReadyBoost using a USB flash drive to boost performance. But left with many questions unanswered in hopes that you can help me. What exactly is ReadyBoost and what does it do exactly to help boost performance? Does it really work that well? I know it requires a USB flash drive or card, but does it make a difference what kind of drive I should use or does it require something that is fast? How much memory should I consider for the flash drive? I've gone through the Internet and read a few articles that mentioned that ReadyBoost does initially help performance in the beginning, but over time the performance gains starts to deteriorate. Is this true? If that's the case, is it even worth getting into? Any help and explanations will be helpful. Thank you in advance.

Would you let your car "go"?
Jun 20, 2008 1:23PM PDT

If you don't know how to maintain and cleanup your computer, you should pay someone to do it or take classes yourself, instead of adding more junk to it to "fix" it and make it faster.

What is going on with these computer novices is like you bought a brand new car but don't bother changing the oil, adding gasoline, water, etc.

If you maintain your computer and keep the drivers updated, check for updates, critical and optional (which wouldn't be showing if you didn't need them), and refrain from saving all your pictures on your hard drive (that's what flashdrives & SD card are for), you can keep your computer up and running for more than 6 years. I've got an XP I bought six years ago & it runs perfectly - I bought a new computer because my daughter was old enough to have her own, the new one has Vista - Vista is awesome because it does most of the updating and maintaining itself with a click of a mouse (look in system tools) - and both are still less than 30% used memory.

RE: What is Windows Readyboost
May 24, 2008 4:56AM PDT

Windows Ready boost is basically Windows using a USB Flash Drive to put a page file on it to use it as extra memory before it hits the hard disk, which is slower than memory sticks and the usb flash drive, and Ready boost, when used with ready boost capable USB Flash Drives, can help performance when a little extra memory is crucial, such as playing a game, using photoshop or another photo editing program, or moving files around, i would suggest 2GBs or more for the size of the USB Flash Drive, as 1GB and lower will hurt performance rather than help it, and look for the ReadyBoost capable thing on the packaging, as that usually means its a bit faster than normal non-readyboost capable drives, and i would suggest using readyboost only when you need the extra memory, as that will keep it from deteriorating quickly.

ReadyBoost is a bit overrated.
May 24, 2008 9:17AM PDT

One big mistake a lot of people make is saying that Readyboost allows you to use a flash drive as RAM. The memory inside a flash drive or an SD/CF card isn't as fast as RAM, which is why the flash drives are cheaper than RAM.

Readyboost is really just an extension of the swap file on the hard drive. Not everything that your computer does can fit in RAM so some things normally are cached on the hard drive. The problem though is that the HD takes some time to find things, whereas a flash drive like RAM has virtually non-existent access time, which makes the computer more responsive.

That being said not EVERY flash drive supports readyboost. Just because a flash drive can copy data fast(20+MB/sec) doesn't mean that it has good access time. Vista checks for both transfer speed and access times for compatibility so having both good transfer speed and sub 1ms access times a needed. A lot of cheap flash drives will fail one of more of the tests for Readyboost compatibility.

A lot of drives on the market now list that they support Readyboost, but there are some drives on the market that support it that don't list it on the packaging so check online.

Grant Gibson has a website that has a good compatibility chart to see whether your flash drive or one you are considering purchasing supports readyboost:

http://www.grantgibson.co.uk/misc/readyboost/

That being said even if your flash drive is supported the benefits are somewhat weak for newer machines running Vista. Tom's Hardware did a story about Readyboost when Vista came out and they found a decent benefit for machines with 512mb of RAM, slightly less benefit for 1gb of RAM, and basically no benefit at 2GB of RAM. Most newer machines don't come with less than 2GB of RAM anymore so unless you bought a very cheap laptop you probably already have so much RAM that there would be little benefit to buying a flash drive for Readyboost alone.

Unless you have a machine with a 1GB or less of RAM Readyboost is unlikely to make a noticeable difference. Even then, RAM prices have fallen to the point where a 2GB kit of RAM regularly is sold for ~$50 and sale prices are regularly less than that.

When Vista first came out RAM was ~4 times more expensive depending upon the brand name and the speed. Readyboost may have made sense then when a lot of machines didn't have enough RAM and RAM was pricey, but most machines have enough RAM to run Vista well without Readyboost and even if they don't RAM is relatively cheap.

My advice is to not bother with Readyboost in most cases.

ReadyBoost Observations
May 24, 2008 1:05PM PDT

I have tried both a "Class 6" SD camera card, and a USB Stick that was "ReadyBoost compatible" and is said to be faster. On one computer, I have frequently needed to run the "chkdsk" utility from a command window to clean up the device since the ReadyBoost cache gets "messed up". I have also had incidents of the ReadyBoost cache simply seeming to disappear.
For speed, start by raising the amount of RAM on your computer to 2 GBytes or more. If you cannot do that, try a ReadyBoost device and get a USB stick that is both inexpensive and fast--preferably "ReadyBoost Compatible". For such a use of a USB stick, the U3 utility that is included on some new USB sticks is probably not needed and could be deleted or disabled.

Readyboost
May 24, 2008 4:30PM PDT

Readyboost is where Windows can cache temporary data on a flash drive, so it has quick access to things that might be needed in the future. Unlike hard disks, flash drives don't take any time to "seek" to the necessary data, so this makes them good for use as cache - better than a hard disk. Of course, a better place for cache is system memory that is not currently in use, as the seek times are the same and the memory can transmit data faster than a flash drive.

If you want to use Readyboost, you need a fast flash drive. A $9 no-name special most likely won't do the job, or will barely improve performance. Fast flash drives usually have their throughput printed on the packaging.

The downside to Readyboost is that it can decrease the operational life of your flash drive. I don't know if the performance gains deteriorate; I see no reason for this to happen. Fragmentation isn't an issue with flash memory, as there is no additional time needed for the drive to seek to the correct location for reading or writing.

The other downside really is that when you have enough RAM to hold Windows' entire cache, Readyboost won't give you extra performance - it might even make things slower.

The very best solution to getting better performance is to increase the amount of RAM you have. Vista is a horrible piggy resource-hog of an operating system, so you really need to put in as much RAM as possible. Max it out to 3 gigabytes of RAM and you won't need Readyboost at all. If you have the 64-bit edition of Vista, you could even put in 4 gigabytes.

Windows Vista increase speed
May 24, 2008 10:55PM PDT

Hello.
Windows Vista is actually an OS that needs a lot of memory to run properly.
Improving your memory means: 1)installing more RAM, 2)using a flash USB via ReadyBoost.In both cases, improvement is obvious, but as you probably suspect it, either the new RAM or the Flash drive must be fast.
I have found out that, only if you purchase more RAM,the fastest your system can support, your windows will improve.2 GB RAM 667Mhz or beeter and with a good latency time is consindered as a minimum requirement for Vista. I, personally, use 4GB 667Mhz RAM with a fast Hard Disk of 7200rpm and the system is super, condidering that my laptop has already 512 MB of graphics card, which means that the CPU and RAM are "released from overload".Nevertheless, the additional RAM is neccessary.

Ready Boost
Jun 20, 2008 2:37PM PDT

It's really too bad that there's getting to be so little good information here, at least not without having to read all the childish rantings against Microsoft/Vista. To start with, come on Lee, can't you find the time to do a little investigation yourself before throwing out hearsay to 'start the discussion'. You offered no real technical background and couldn't provide a first hand assessment. Gee, where's the journalistic integrity - oh, I forgot, we're just in whiney-weenie land here. One person replied that Ready-Boost will only provide about a 10% increase in performance. Let's see, 10% just by throwing on a thumb drive; yeah, I can see why that's not nearly enough. There simply isn't enough conversation about the concept behind RB: what does it do? how does it work? No, that would be too technical. Better to just stick to the inane bashing that goes on. I read fewer and fewer of these "community newsletters", less and less often. Too many children with gripes and not enough adults to help steer the conversation.

Give Lee a break!
Jun 22, 2008 10:44PM PDT

"Journalistic integrity??" C'mon man, this is a place for people to give their experiences about Ready Boost, not an official CNET review. Lee's job isn't to review the technology, it's to facilitate the reviewing process. See the "Manager, CNET Community" below his name?" Shouldn't that influence your opinion as to whether he's doing a good job? I think he did a fine job.

As for being upset about the Vista bashing, maybe the folks at Microsoft who've paid you to blog about Vista should actually put a decent product out there. Why are so many people sticking with XP? Why are computer manufacturers still offering XP as an option? WHY DOES VISTA EVEN NEED READY BOOST? That should be the real question and the real topic of discussion.

who cares how big the flash drive is it doesnt matter much
Jun 24, 2008 10:59PM PDT

"You Need a Flash Drive at least 4 GB big if you use all of it for Ready Boost it should be Perfect!"

the size of the flash drive is of little consequence to the speed that it will provide. rather look at the access times / write speeds of the drive. and also 4gb is too much it will not all be used. 2gb is about the most you will need.

How ReadyBoost works

ReadyBoost works by putting a file on the flash drive that will reserve space. Then, the computer uses the amount of space reserved as extra RAM.
More info here:

http://www.microsoft.com/windows/products/windowsvista/features/details/readyboost.mspx

If I were you, if you want to speed up your system, I wouldn't trust Ready boost. I have a 4GB flash drive, I want to it for want it was designed for, not speeding up the system a little bit. I would get some more RAM at http://www.crucial.com At Crucial, you can run a scanner teeling you how much you have, what you can get, and prices. If you currently have 1GB, go up to 2GB. If you have 2GB, 3GB should be enough.

Good Luck!

Windows Readyboost
Jun 20, 2008 10:50PM PDT

Hi,

Some time back, [4 years ago] having read the same repetitive advice in Computer Magazines and those on the net. I thought long and hard about keeping my computers as fast as they were when new and the answer was there for all to see.

You start up a new computer and load a program on, it therefore now has more of the Hard Drive capacity used, and this is repetitive thereafter, thus, slowing down our computer. I started with each new computer to put only on Anti Virus, SpyBot, Ad-Aware SE, and CCleaner and these are all not to heavy in usage. I bought an external HD and all [and I do mean ALL] work etc was load onto this drive, and since then, my computer remains virtually at the speed I received from manufacture. With the advent of 4 to 10 gig flash cards this would be another way to achieve the same, but, with a limit depending upon you demands.

Now, the most important reason for using an external HD was as stated above, however, more came to light, if, say, for instants your computer crashes or needs repairing, then [for most] your information goes with it [Bank, Credit cards and personal info etc] therefore, keeping your computer HD as new as it arrived, keeps your speed & your computer safe.........its just a thought Happy

What is Windows ReadyBoost and does it work?
May 27, 2008 7:48PM PDT

ReadyBoost is basically a USB flashdrive that allows Windows to
store information on its memory,instead of using your RAM (Random
Access Memory).I use a Vista/Linux OS and have 1.5GB of RAM.Yes,
ReadyBoost does work but your USB flashdrive should be 3x your RAM.
If you go to Help and Support(Start Menu) and type in ReadyBoost,
you can read the specifications.Lots of luck.

Vista ReadyBoost
May 28, 2008 11:16AM PDT

ReadyBoost I tried in my computer. I couldnt find any difference in perfomance before and after using readyboost.

Well, I got in trouble using readyboost also, that while using readyboost, I kept the system in sleep mode for some time , then after few minuts i changed to the normal mode, this made a bad sector in the harddisk, this I tried 4 times after re installing vista, and same thing happened, harddisk making a click sound and read write delay showing. Then I stopped using Readyboost for some days, reinstalled Vista. Using readyboost without going to Sleep mode. Now no preoblem..Now fear to go sleep mode with readboost is anabled.

So I understood that, readyboost is actually the swap space for windows, so it uses usb memory as swap instead of Hard disk. When u enter in to Sleep mode, data is retained in the hard disk, when we come to normal mode, fast reading of data from hard disk making errors.

Thank you

May 31, 2008 1:25PM PDT

Readyboost is actually a file where system processes are offloaded into. It does improve performance on day-to-day tasks but does not increase performance in games. For readyboost to work best, it is recommended to use fast memory cards, thumbdrives etc. A Readyboost file will be created and the sapce occupied by the file(user defined) will not be available for use. However, readyboost does not improve performance much on systems with 3-4GB RAM as there is plenty of memory for the PC to use but it works best with 1-2GB RAM.

Readyboost is about on par with Vista. (and that ain't good)
Jun 20, 2008 12:02PM PDT

I had a Vista machine (I say HAD) with 2 GB ram which, like other Vista machines, was painfully slow in comparison to the machine it replaced which had an older OS and approximately 1/2 the computing capacity. I heard about readyboost, so I plugged a 4 GB flash drive into a USB port and instructed the computer to devote the entire drive to readyboost. I could tell absolutely no performance difference, but every few days, the ready boost would show a bit less memory than previously. Eventually after only 3 or 4 weeks, the flash drive was "dead". It wouldn't work in that application or in any other application either. I had a 2 GB flash drive hanging around, so I replaced the now totally dead 4 GB drive with the 2 GB drive. Within a couple of weeks, the 2 GB drive was also dead.

Now I have no scientific data or scientific evidence to support my contention that these two flash drives would still be functioning as document and photo back-up devices if they had never been relegated to the ineffective readyboost, but I had lost no flashdrives prior to, nor any since this experience. (I have also since then replaced the entire computer with another one with approximately the same computing power but an older OS and it is performing fantastically. ----without readyboost)

ReadyBoot overview and experience
Jun 20, 2008 1:56PM PDT

ReadyBoost maintains a copy of some of the most recently accessed data on your PCs hard disk in flash memory such as a USB memory stick. The premise of ReadyBoost is that small amounts of data can be more quickly read from flash memory while larger, sequential chunks of data can be read from disk faster. When Vista needs to retrieve small bits of recently accessed data, the flash memory is actually quicker to access than a hard disk drive.

If your PC has 2GB of RAM (Random Access Memory) or more and you only use a web browser and a word processor, ReadyBoost may provide little, if any, benefit since both applications can be loaded almost entirely in regular RAM. If you run multiple programs and you find that your PC's hard disk is working hard when you switch between them or if you run guest operating systems in VMWare or Microsoft Virtual PC, ReadyBoost can noticeably increase performance.

ReadyBoost does not pose data corruption risks as it maintains only an encrypted copy of what is already on disk and is not the sole copy used. You can actually remove flash memory acting as a ReadyBoost device from your PC without losing data since Vista will simply read the needed data from the hard disk instead.

I usually have a Sandisk Cruzer Micro 2GB USB drive configured for ReadyBoost in my HP DV9000 with 2GB of RAM. When I play games such as Crysis or Age of Empires, switching between them and my web browser is much quicker than without ReadyBoost. My machine with Vista and ReadyBoost is much better at multitasking than it was with XP and the same amount of RAM.

Your flash memory device will have to be USB 2.0 compatible and meet some minimum performance requirements. I've seen flash memory device manufactures advertise ReadyBoost compatibility, so it shouldn't be too hard to find a compatible device. Worst case: Spend $30 on good USB flash drive and set it up as a ReadyBoost device (Vista should prompt you with this option upon first insertion if it's compatible). If you don't notice any improvement, open My Computer, right-click the device, select Properties, click the ReadyBoost tab and disable it. Now, use the flash drive to back up some of your most important documents, music, and photos and move them between PCs if necessary.

Beware large USB flash drives
Jun 21, 2008 2:27AM PDT

I'm glad I was albe to help. A few words of caution if you're looking for a 4 or 8GB drive. When I bought 2GB Sandisk drive (over a year ago), I also bought a 4GB Transcend USB flash drive figuring the extra space would help. Unfortunately, the larger drive used slower memory and didn't pass Vista's ReadyBoost performance check.
Just make sure whatever you buy mentions ReadyBoost compatibility or, at the very least, save your receipt so you can return it if it doesn't work.

Does Not help if your system memory is 2GB OR MORE
Jun 20, 2008 2:44PM PDT

I've been using Vista Home Premium for a year and two months now.
Ever since the beginning I thouth that ReadyBoost was going to make a difference in speed but it did not.
I have a 3 year old XPS2 with 2GB of Ram and a 100GB hard drive with a 256MB video card from Nvidia.
I have been doing a lot of testing with different free applications such as antivirus, Registry cleaners, firewalls. But At the beginning I continue to use programs That I was very familiar with.
1-ZoneAlarm Free Edition - For Vista.
2-AVG Free Edition - for Vista - never tried Ver. 8.0.
3-Used a driver for my touchpad for XP because Dell drop the ball and never came up with a driver certified for Vista and my laptop.
4-Vista Driver for my Netgear wireless pc card.
5-Auslogics Register and harddrive defragmenting utilities.
My laptop regardless of what I did alwasy took 2 minutes and 30-50 seconds to boot. These was using ReadyBoost.
After testing these and others to see what they offered, my system crashed and I have to re-installed Vista.
I decided that I was not going to take the chances of loosing my files pictures and music anymore by installing it to the same partion as the operating system and programs. So here is what I did which brought my laptop to boot in 1 min. 05 seconds.
A-Partion my hard drive in two, Giving about 35-40 GB for OS and Programs, and 60GB for all my files. This helps, because the OS now tracks the OS and Program files in a smaller area of the drive, yes the OS keeps tracks of what is on the other partion but does not access the entire drive to do so, if you are not looking for those files.
B-Installed Vista clean, all patches and SP1 and any other patch up to the point when I was ready to intalled anything else.
I think this makes a big difference because there is no programs that may have changed the register or any other windows file.
1-Changed from ZoneAlarm to Comodo's Fire wall which is free.
As soon as I took ZoneAlarm off, my computer started booting faster.
Comodo is fantastic and it is very well designed for Vista. I little harder to use but if you take the time you will see the settings are not that complicated. I am still learning, using it for about 1 month.
After seen how well Comodo worked, I also disable the Vista firewall because it assumens all programs in your computer should have access to the internet, there is a way to set rules but is complicated. Comodo learns and advises you if there is something it cant handle.
2-Changed from AVG to Avast Home Free, again another increase in speed. In my opinion, Avast is also very well design for Vista and has a lot of good features.
3-Found on Dell site a TouchPad driver that even though is was not for my laptop works great and loads properly.
4-Vista Update had a driver for my wireless card and changed to that and uninstalled the Netgear Driver. I also allow vista to handle the connection to my router which is working great.
5-Stop using Auslogics registry and harddrive defrag because they never appear to spead up my computer. I use the defrag utility from Vista because it takes into account the Prefetch, but with one exception, I use it through the command line as Admin. and execute command defrag c: -f -w -v (f=force defrag of all volumens -W=forces defrag of all files regarless of size - v=verbose.
When you use the GUI it won't defrag if your volume is less then 1% fragmented, which is why I run it from the command line to force it.
6-During my testing I found a great application Revo Uninstaller.
It really does a good job at finding entries programs leave behind, eg, Lava Soft, left over 200 entries in the registry and other files.
I always use this to uninstall programs so that my hard drive is cleanner why waste space right.
Last I use CCleaner to clean emty entries on the register as well as any other temp files left on my computer. It does a great job and it is free.
7-I took the 2GB SD card used for ReadyBoost two weeks ago, with no degradation in performance and increase the Page File to 4GB, I know is not recommended (some rule about the page file being a % of your ram)and set it as static by indicating the values for both min and max,but all of these changes combined made a big difference.
Bottom line, Clean your hard drive from junk you don't use with Revo to uninstall programs. Split your drive if you now how to use partion software, Vista has one built in. Defrag your drive once a month through Command line. Find the latest and best drivers for your computer, but before you install the new one alwasy uninstalled the oldone completly.
Last defenetely use CCleaner to clean the register, Everytime you uninstalled a program, with Revo there still some reference left behing (no one program is completely perfect) which CCleaner will handle. There was mentioned that cleaning the register is being paranoid. but windows hss to load all the references in the register because it thinks you still might need to use a program reference in the register. Being the case the bigger the register with useless things, the longer the computer will take to boot.
Good Speed Buddy.

Excellent journey!
Jun 21, 2008 6:06AM PDT

Looks like you went down a similar path I did with XP. I haven't tried Vista yet; but some of your advice works very well with XP also.

I've heard Revo is good; I must try it, but I like RegSupreme Pro so well I am definitly going to buy the license. A LIFETIME license is only $16!!! Don't worry - Macecraft has been around practically forever; when JV6 was free the company continued to, and still does honor the lifetime licenses for their product.

It has a plain Jane GUI, but makes up for it in droves with its ability to clean horrible software like Symantec out of your computer and has found hidden programs, I didn't find before, lurking in the system files and removes/uninstalls them, you won't need to run CCleaner after this, it won't find anything!

Good to hear of some Vista features working well such as the defrag program; sorry Auslogics doesn't cut it, I was going to try it on XP next.

NOD32 is a vastly superiour AV for XP and x64; I would suspect it does even better with Vista; and I doubt it has to invade the kernel like crapware Symantec!

Just thought I'd add some comment; thank you for providing valuable and enhancing information for CNET readers everywhere.

Running Processess at startup
Jun 21, 2008 7:24AM PDT

Thanks for your comments.
I kind of forgot to mention also that both win xp and vista have the MSCONFIG.EXE where you can disable items that start at boot time.
The problem with this module is that the register settings load first and then the module executes the items you don't want to load. This adds to how slow xp and vista work.

Revo has several modules, including Auto Run Manager, the difference between Revo and MSCONFIG, That I have noticed, is that Revo actually disable the program at the register level and then gets out of the way, unlike MSCONFIG, which always appear to be loading into RAM to track what to load and what not to load. In addition, if you right click on the list of autoruns in Revo, it gives you a list of choices on what to do, including but not limited to looking up the starup process online so that it helps you decide what does it do and if it is absolutely necessary.

As someone mentioned, a good example is ADOBE FAST READER LUNCHER, IS NOT NEEDED. If you open an adobe file, it will give you a msg. indicataing that that process is not running and that you may see some problems with adobe itself, not true, it displays the file just the same.
Now the autoupdate process for adobe might be helpful because it reminds you of updated versions, then again you could manually run, CHECK FOR UPDATES within Adobe reader itself.
I have tested MSCONFIG and defenetly have noticed decrease in performace.
MORE ABOUT READYBOOST.
The files store in ReadyBoost drives are very small in size, someone mentioned files like background procesess which appears to be true.
But remember, ReadyBoost files are just a copy of what has been loaded into memory already, hence if the OS needs memory space from RAM to be allocated to other programs it will unload those procesess that are not absolutely necessary for the OS and use the copy in ReadyBoost itself.
This is just an opinion on how it seems to work derived from spending alot of time reading the performance logfiles for readyboost.
With 2GB ReadyBoost it always show very little speed performance and accesess.
With 2GB RAM, opening all my programs, background procesess, internet explorer with several tabs opened, my Ram never goes beyond 49-55 utilization as meter by the CPU-RAM GADGET on the Windows Side Bar,
this includes, running Cnet TV episodes, Windows Media Player 11 playiing songs, running all of the staff I use on my computer.
My CPU on the other hand is going crazy between 60 to 100 % being that it has only one processor running at 2GHZ.
I help my syster buy an HP TWO PROCESSORS WITH 3GB of ram, the video card is chip Nvidia, 128MB of dedicated RAM, Runs very fast.
The combination of dual core and 3GB or Ram is defenetely good.

That's all, everyone seem to have different experiences and good opinions as to what runs best for them.
EXPERIMENT, EXPERIMENT, EXPERIMENT, Key words with XP and VISTA.

Experimentation is great, I do a lot of work on my honeypots to test AV and AS ware, so I know where you're coming from.

I would rather save time and listen to thoughful comments from people such as yourself though!

One thing about Adobe, I let Secunia PSI tell me when there is update; because, just as in the Fire Fox 3 debacle, I would rather wait until all vulnerabilities have been fleshed out from the updated versions.

I've had such good luck creating PDF files with Open Office I am thinking of uninstalling Adobe Reader! I can use it for my reader from now on! Of course I don't know how well page security features translate in that process, so I must EXPERIMENT, EXPERIMENT!
