I was going to post this same deal. Thanks OP.
Jump on this drive people. It's a very flexible drive, these are some of the newer generation technology drives, the are 7mm thick so they can fit into any notebook or ultrabook. They are 6GBps Sata III, have 32MB cache, and are 7200RPM. They are second generation technology, so they are a bit faster and probably more reliable that they previous z5k500 drives that came out.
HGST is the budget line of Western Digital. Basically you get a getting the high performance western digital at a much lower price.

Once you get rid of your PS3, you could go on to use this HD in something else like a gaming laptop or media center. Hell, you could probably use this to upgrade the PS4 or next Xbox, since more than likely MS and Sony will cheap out and use the lowest spec'd drives possible to conserve on costs.
Shipping is free as well.
