Pros: Replaced 2GB DDR3 with this. Not so sluggish when running lots of programs. Took about 5 minutes to install.
Pros: This drive does improve performance. Here's my results with a clean install and about 15GB of programs installed.
Startup: 22 seconds
Deep sleep wake: 16 seconds
Photoshop CS4: 3 seconds
Firefox: 2 seconds
Word 2011: 1 second
Cons: 4 stars because the drive came with the 1.1 firmware. Unfortunately, this firmware version was not compatible with deep sleep (and would force a reboot after waking). The 2.0 firmware seemed to fix this issue but I had to flash it with a Windows machine since no OSX tool is available. If you don't have access to Windows, you'll have to RMA the drive to get it flashed.
Definitely fast, but not as fast as I had hoped.
Overall Review: I'm using this drive on a 13" Macbook Pro with 2.26Ghz Core 2 Duo, 4GB DDR3 ram, OSX 10.6.5.
