Went out, bought it, swapped drives, and IMMEDIATELY noticed a speed difference. Boot times of Snow Leopard are 3x faster than they were before. Just amazing.
Here's the drive I bought if you haven't already looked at it. Not a lot of detailed specs: http://www.compusa.com/applications/...442&CatId=2682
I just need to get Windows 7 and Ubuntu 9.10 restored and I'll be finished. Really looking forward to seeing those two perform.
Another factor that's probably making things faster is the fact that this thing has no bad sectors/blocks (yet)
