It is a 2 TB Seagate backup plus external drive. Technically, this is a Mac/ Windows back up drive, however, since I primarily use 'nix, I wiped that software off of it since I bought it for the space.
It says it has a max throughput of 120 MB/s, and that is probably true, but during my testing (transferring 249 GB of vm's), it was consistenly averaging 80 MB/s, probably fast enough to actually run an OS on comfortably, although maybe not fast enough for gaming, if your into that

Will test running some video streaming from it later on today, but for a 2 TB drive around $60., I got no complaints or problems noticed.
