the one I got was an internet 5900 rpm hard drive, the cheapest you could buy, not an external, not slim, etc... what was the one you bought?
the 2 terrabyte internet 5400 rpm is not for 200$, less quality more price.
if we look at external disks and USB powered disks. external 2 terrabyte disks easily shoot above 200$, not even with a wireless or a fire wire or any special settings, just the storage

I also wish I could find a 2 terra for 140$
