I bought an Intel X-25M 160gig to upgrade my laptop to Windows 7. When I got it I wanted to see how fast it really was, so I used a partition manager to move my old Vista system to the new drive. No other changes. Booting time went from 230 to 100 seconds. Starting VS2008 went from 44 to 14 seconds. Then I wiped it clean and installed Windows 7 64-bits... :omg: BTW: The old disk was a 7.2K Seagate Momentus
