Online backup provider Backblaze have published results from a study they have performed on drives used for their service. This study includes 27,134 drives, and use standard consumer models from Toshiba, Seagate, and Western Digital. So which hard drive should you buy? If their results are any indication, you could say “anything but Seagate”. At least for the 1.5-3 TB range.
I would recommend reading their blog post for full details, as it’s quite interesting to see their process. For what it’s worth, they are still buying Seagate drives – they say the 4TB models are reliable enough, and the prices are lower than the rest. If you’re in the market for a lower capacity drive though, you might want to spend a bit more to get a Western Digital or a Hitachi drive.
