Replace 15" macbook pro 2011 harddisk

I have a friend who wants to replace a harddisk in a 15" macbook pro of 2011. The current disk is 320GB. She wants to replace it with a 1TB drive. There are two harddisks at the moment that I know of.

(a) Western Digital, which is 12mm high
(b) Samsung, which is 9mm high.

Will the WD disk fit? The Samsung is not as available as the WD disk, in her town.

I reccomend the following Hard Drive for your friend's MBP.

Western Digital Scorpio Blue WD10TPVT 1TB 5200 RPM 8MB Cache 2.5" SATA 3.0Gb/s Internal Hard Drive -Bare Drive

It has high reviews, is only $109, and will fit. Any internal hard drive that is spec'ed at 2.5 inches will fit in the macbook.


Your friend will save by buying online... more than likely

why not get a 7200rpm drive? May aswell since you're opening up the laptop.

Heres the manual here which details fitting the drive: http://manuals.info.apple.com/en_US/macbook_pro_15inch_early2011.pdf
Your help has saved me hundreds of hours of internet surfing.

I hear that 7200 rpm drives get really hot, too hot. That is what I heard about two years ago, and I can't believe that it's that much different nowadays, maybe it's worse. And I haven't seen any 1TB 7200 rpm drives yet, not notebook size. The manual says nothing about 12 or 9mm.

We ordered the Samsung 9mm drive, and I hope that works well.

R7AF.. 12 or 9mm does not matter...............OVERALL there is either a 2.5" or 3.5" standard...

I meant to write "2.5" external case, not 2.6".

See http://support.apple.com/kb/ht1310 for help choosing a device on which to boot the system.

Turn on, or restart, your Mac (or MacBook Pro).

Immediately press and hold the Option key. After a few seconds, the Startup Manager should appear. The Startup Manager scans for available available (bootable) volumes.

This works fine with USB drives, not as fast as Firewire 800, but then again, the USB 2.0 cases for 2.5" drives are cheap, like $10 plus shipping.
