It works great, my benchmarks easily hit 150MBps sequential read/write. My one issue with it though, and this may be a problem with all hard drives that are not used often is that it will spin down when not in use for X minutes. I use this drive for storing FRAPS videos, and only FRAPS videos, so when I start recording FRAPS lags me pretty badly because of the 3-5 seconds it takes the drive to spin up due to inactivity.
Anyone know if theres some setting to tweak in Windows 7 to alter the spin down time? IE: If not used for 1 hour then spindown?
