The first one looks like the OEM product so it will come in a brown box and drive only. The 2nd SSD is a retail box and comes with a 2.5" => 3.5" mount for desktop systems.
Hmm odd, i got the retail one for $250? Must be a mistake from tigerdirect some how.
The OEM is $265 and is in stock, while the one they picked for me (retail) for $250 is backordered for a week now, ugh!
