Here is a good article on the new terrabyte drives.

Good read on the differences.
Hitachi and Seagate tie for the best performer.
WD is the "greenest" and quietest.
Seagate has the best warranty with 5 years.
Samsung is still absent.
They also mention the Flash drives in the article and allude to the fact they are slower than sata?!
FYI: I have 12 of the Hitachi's in test using IOmeter to validate the performance and I am just now installing 16 of the Seagate's for another custy... FEAR MY 38TB of storage!
