New Macbook Pro 13 inch has 1.5 Gigabits SATA connector

by M_Man633 / June 15, 2009 10:22 AM PDT

I have decided to buy a 13 inch Macbook Pro and just recently found out that the SATA speed has been DOWNGRADED (***!!!) Will this affect the speed of a stock (from the apple website) 320GB Hard Drive in any possible way? If so please tell. I have heard mainly from people that have upgraded themselves with a SSD(solid state drive) Is this true and only relevant for the SSDs? Or is this a problem for normal HDDs too? Help Please!(keep me away from buyers remorse) Thanks

Many PCs do that.

It's just a shade more reliable and one of those "on-paper" might be slower. I've tried hard disks with the 1.5Gb jumper on and off and only in benchmarks found it to be noticeable.

Sounds like a good move. Give up a tiny bit of speed for more reliable operations.

Relyability not an issue

I have never heard of SATA II drives being less reliable than SATA I, do you have a link for that?

It probably doesnt matter much with the current 5400RPM hard drives being shipped with the MBP, but its pretty uncool of them to hamper future upgrades like that. And it DEFINITELY matters if you plan on going SSD.

Sorry to see you upset over a minor ripple in the designs. Good luck and don't buy stuff you don't like!

I'm not upset, just giving the facts.

Simple. Take a few machines with 3.0Gb SATA and test them. Now pull the hard disk and put that jumper on and re-test. Only in benchmarks could I tell I put the jumper on. The difference was less than a percent point.

Have you done such tests?

And just a preemptive question. Did you look for such tests? Hint: I think this test has been done to death. I'm ashamed to say I did it too.

I never said otherwise

I never said the SATA1.5Gib/s limit would affect everyone, just those looking to SSD's a few years down the line. Of course, the 5400RPM drives currently offered with the Macbook Pro's will never hit the 150mb/s barrier.

By the way, I've been doing some googling and still havnt found anything that says SATA II is less relyable than SATA I, do you have a specific source?

Having to deal with some untold number of machines each year one of the tricks of the trade to make a machine behave is to.... You guessed it.

I'll leave it to you to wonder why.

I did not do any tests but I found some graphs some other person had made on the macrumours website

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
