I have a 1.5TB GoFlex USB 3.0 for evaluation. Its 22mm thick. I am speculating but judging by the performance its a green edition drive for sure. There are 2 models within the 1.5TB. The specific one that I am evaluating is STAA1500301 and this one comes with 3 years manufacturer's warranty mentioned on the box. The drive comes with Seagate Dashboard software, offering share file support between PC and MAC (basically an NTFS installation file for Mac).
When I got this drive, the softwares wasn't there (whoever tested it earlier had pirated copies for l4d2, vintage, 06 and other *ahem* stuff *wink*wink*) but if its the same as the GoFlex Slim I tested then the backup is nothing more than a media backup.
