IDK, I have a kingwin SSD (supposedly one of the better ones) in my thinkpad x40 and it is alright but the pair of u320 cheetahs in raid-0 in my hp pc are much faster.
The best thing about the SSD though is that the machine makes NO noise at all
and power consumption will often drop below 3 watts (that's for the whole machine) when running on the battery, more often it is at 6 or 7 watts when playing games though. Before, it was about double, maybe 6-10 watts.
