I have an SSD from a T400S installed in a Fujitsu P1630. It's the Toshiba variety that's been shipping recently (looks like they started producing them in June).
Small random writes are fast, similar to the Intel X25-M. Sequential read is slower, but sequential write is usually faster than Intel's drives. Overall a very good SSD.
