And totally off topic:
At work, our analysis server's storage array just got upgraded to 20 250GB Enterprise grade SSD. Utterly mindblowing performance on complex simulations. The coolest part is the array chassis is only 2U and has hotswap bays for 32 2.5" drives.

It is only a matter of time before SSD replace everything (except maybe nearline storage). The only con is cost and that is falling by about 50% every year (faster than Moore's law).
Everyone needs to experience a huge array of enterprise SSDs at least once in their life.

It is very impressive. And, I doubt you can make your throughput graphs dip when you shout at the array, like you can with regular drives.
