I ordered the one from Amazon. It's slightly more awesome looking. This review
says it is this drive
inside, which means the internal disk is a 5-year-warranty part.
Not bad at all. I don't know what the rationale is for external drives costing less than what they contain, but I won't pretend to complain about it.
...And it appears the other model (the Expansion) has the slightly newer 3TB model drive. Oh well.
Update: Whoa the new drive has 3 platters. 1TB platter! Thats much better than a 5-platter drive. Trying to cancel...
Also. Holy crap 3TB 7200RPM drives are FAST!!! Just shy of 200MB/s. Wow.
Update: Whew, yes the cancellation went through.
Silverstone SG06: 2500K@stock, GTX 670, a 3TB HDD I ripped out of an enclosure and crammed in there upside down, 2x120GB SSDs, and the cover can still fit on it but I leave it off so the hard drive can breathe
