a refurb hard drive is really awesome if you don’t care too much about your data. You can get a brand new one in this size from places like newegg for $15-20m more, which will have a 3 or 5 year warranty depending on maker.
No, this won’t work in a laptop. No, this won’t work in a PS3. Most laptops within the last 2 years, and all PS3’s use SATA hard drives in the 2.5" form factor. This is only suitable for use internally in a PC desktop or mac pro desktop, or popping it into an external enclosure (about $20) and using it externally. In any scenario, assuming you have no valuable data. As an IT professional there is no way I’d buy a refurbed hard drive for nearly any use.
I’ve got one of these (bought new, not from Woot), it’s been great. Got some empty drive bays to fill. Hm. Price is tempting…but I don’t want pǝqɹnɟǝɹ.
