This is an OWC 240GB Solid State Drive. The drive was purchased in Februrary (less than a month ago) and it still has it's 3 year OWC warranty. The reason I am selling this drive is because I upgraded to the new Macbook Pros(2011), which have a SATA III connector and and this drive uses a SATA II connector. This drive is crazy fast, I know people say that a lot about SSD's, but if you are upgrading from a regular hard disk drive then this is going to be an unbelievable performance upgrade. Everything loads quicker, the machine boots faster, everything is just more snappy and as a result makes you more efficient at doing your work. There is no place else to purchase this drive from besides OWC so the only way to get a discount is buying it used. OWC charges $500 for this drive plus tax which totals at $520. Thats what I payed for this drive. I am selling it to you for $485 and it has only been used for 2 weeks. Please don't hesitate to contact me for further details/pictures.
