Just a few months ago we were impressed with Western Digital for cramming an entire terabyte of storage into a mobile hard drive that was just 7mm thick. But now Seagate's come along to steal WD's thunder with the ultra-slim 2.5-inch Spinpoint M9T that manages to double that capacity to 2TB inside a drive that's just 9.5mm thick.
So you're getting twice the capacity at the cost of just 2.5mm in added thickness -- that sounds pretty reasonable. After all, at 9.5mm thick the M9T is still the thinnest two-terabyte hard drive you can currently buy. The drive will also be available in a 1.5TB model as well, which will presumably cost slightly less than the 2TB model's $US129 price tag. [Seagate - Samsung]
