Pros Lots of storage and works on gigabit network.
Cons I did not like the 'Out of the Box' software used for accessing the drive.
Summary The My Book World Edition NAS 500 GB version is very easy to get running. The problem I had was with the software the they want you to install for accessing it. They call it WD Anywhere Access and it is powered by MioNet. This software gives you the ability to access it from the internet or within your own network. This software was overkill... I just wanted something I could call 'F Drive' and copy my backups to. Instead this software made every drive on my PC available to my laptop and vice versa... not what I want at all.
My PC is running XP Home Edition. Using the WD Anywhere Access software I had some connection issues. I would boot up and the network drive would be available. If I opened the WD Anywhere Manager tool, it would tell me the NAS was not available. My Laptop is running XP Pro and I did not have any of these issues.
Before boxing it back up and returning it, I checked out Western Digitals help site. I finally found a Knowledge Base entry that gave step by step details on creating a mapped drive without using the WD Anywhere Access and I am now happy.
Pros The NAS MyBook World Edition II is an awesome 1 TeraByte!
Cons MioNet is total crap, unfortunately WD doesn't tell you that you don't even need it to access your drive!
Summary Also, if you check your network activity you may find (as I did) that the drive is contacting some IP address in France about every 15 to 30 minutes. Nothing is being sent but is this really necessary? The IP address is 22.214.171.124. My firewall logged the activity, Ethereal captured the content, which as I said was nothing. Further digging into the IP address suggests that it may have connections to MioNet.. maybe. I have done nothing further but I plan to call WD and ask them *** is this for. I love the drive, works flawlessly IF you avoid MioNET. -Si
Pros Ethernet connection, 2 500 GB harddrives for 1 TB of storage. Simple stand alone networked storage.
Cons Extremely noisy cooling. Buy aTargus 'Chill Mat' for $19.00, put your MyBook on it and the noisy MyBook fan stays off. The hard drives are not easily swapped, must be sent to Western Digital.
Summary Buy the 1 terabyte version at Best Buy for $320.00.
Data transfer rate via ethernet is ok, you can watch video or listen to music. You can't transfer big files and access (play) video/music at the same time! I have 600 GB on MyBook right now.
The 1 TB MyBook has a very noisy cooling fan, which runs at room temperatures of +75 degF. I bought a $19.00 Targus 'Chill Mat' (2 quiet cooling fans) for notebooks, placed MyBook on it and the MyBook cooling fan stays off. Can't hear the 'Chill Mat' fans at all.
Use of standard Western Digital SATA 500 GB drives for replacement would be handier.
Pros looks nice
Cons became inaccessible after a week
Summary Unless you really, really want to access your files remotely, do not install the mionet the software. After connecting it to your router, find the drive with your browser at \\\mybookworld then map it to your computer and go from there.
Any files you put on the drive using mionet software cannot be accessed without the software.
Suddenly, after about a week, I was never again able to access the files I had loaded on, despite three phone calls to second level support.
Even after using the technique described above for bypassing the mionet software, I could never train my firewall to accept the drive and let me load new files on the drive. I'll be taking it back to the store where I bought it (Best Buy) and will lose my files in the process.
Pros Easy Setup
Cons Ethernet Slow
Summary What I read in these reviews is stay away from MioNet. I guess I got lucky and from the get go I did not want to install MioNet mainly because I had no interest in accessing this remotely. Lucky for me it seems.
Setup is simply. Analyze your network ip's and locate the ip for the drive. In my case it was 192.168.1.92. I pulled this Ip up and this is where you can access the web base WD Shared Storage Manager software. This is the OS software Control Panel built in and loaded on the WD drive. From there you can assign users and shared or private folders. You can rename the drive itself. After you rename it then from your internet browser type \\yourname and hit the enter key and it will pull up through explorer your folders on the drive. From there you can map it to a drive letter. Then you install the Retrospect Backup HD Software to backup or copy to your mapped drive. This backup software is very easy to use.
I give it a 9 out of 10 only because these directions should be published and not rely on this MioNet software which seems to be JUNK.Updated
This MioNet software os the WD Anywhere Access software. DO NOT load this software. Just install the Retrospect Software. Retrospect by EMC is used on many external hard drive kits for backup software and is a very good and inexpensive program.Updated
When I said ethernet was slow, I did not realize it was really slow. It is suppose to be 10/100/1000 Gigabit speed. I was copying from PC to this device and it was moving along at 10/100 speed because of the switch that is was going through.
Now I have about 10 years of data with a lot of music files which comes out to about 300 gigs. So I shut it down in the middle of copying and swapped out the switch and added a new Gigabit 10/100/1000 switch. Now everything is Gigabit and I figured it should be on paper at least 10 times faster and I would certaing have settled for 5 times faster. NOT
There is absolutly no difference in data transfer speed. Now after it is all loaded, which is refered to as seeded, then performing a backup or copy is ok because it will only transfer what has changed and which case would take 10 to 15 minutes. For example of you have made changes of a 2 to 3 gigs on your hard drive, then this is all that is updated.
A USB 2.0 data transfer rate is faster than this device can perform through ethernet.
After final analysis, I am bringing it back and I am going to try out the 300 GB HP Media Vault for just $45 more. It also have a 10/100/1000 Gigabit connection and can be used as a print server.
