Crucial SSD's: 64gb, 128gb, 256gb at time of posting. Direct from Crucial (refurbished).
*** 30 day warranty ***
Going by some of the comments people have posted, the ONLY downside to this offer is that there is a 30 day warranty on this drive. SSD drives do have high failure rates so it is a bit of a gamble.
