Heres a 480GB SSD for even less with similar specs: http://www.amazon.com/PNY-480GB-CS1111-internal-SSD7CS1111-480-RB/dp/B00TIJMEV2/ref=sr_1_51?s=electronics&ie=UTF8&qid=1438635521&sr=1-51&keywords=480gb+ssd&refinements=p_36%3A1253506011
It seems like the same versions ~~(or slightly newer versions, not sure, just guessing based on the model number)~~ (they are the same versions) of the ssds are available on amazon for the same prices.
