Yes, although we would recommend the BarraCuda range for general PC use as the IronWolf Pro is specifically designed for NAS storage.

Purchased this drive to replace it's predecessor, which was a Seagate NAS drive purchased, at the time, for it's build quality and ability to survive in the NAS environment. Sadly, almost exactly three years after purchase, or, to put it another way, at the end of it's warranty period, it'r predecessor quietly, and efficiently died. Purchase of the Ironwolf is based mainly on the fact that I get a five year warranty with this NAS drive designed to survive in the NAS environment. I expect it will go the same way as all other mechanical NAS drives but, hopefully, Seagate will honour the terms of the warranty, unless I've missed a bit of small print that says, ubless it is mounted with a certain type of Titanium/rubber screw then the warranty is null and void. It wouldn't surprise me in the least. On the plus side the drive works as expected, i.e. it's hosting my pictures and music files with no apparent problems but, at this prices, you'd expect that :) Should you purchase one? If you want the peace of mind (hopefully) of an extended warranty period then yes, if you don't care about such things then, probably not, you could save a few quid and buy a cheaper drive which might or might not last as lone. It's a minefield out there folks but, I have found Seagate support to be quite helpful when he inevitable happens.
