Backblaze Reveals Its 2016 Hard Drive Failure Rate List
Every year online backup solution provider Backblaze releases a list of their hard drive failures with information on the hard drives storage capacity, brand name, number of days in use, and most importantly percent of failure. It’s alarming to think a hard drive would fail today – we store our whole lives on laptops, phones, and desktops. Knowing the best brands to buy can keep your data safe, and in Backblaze’s case, keeps their costs down.
Backblaze’s experience will influence others
Based on Backblaze’s experience last year, the best drives would include 4 TB Toshiba MD04ABA400V and the 8 TB HGST HUH728080ALE600. Both of the hard drives, surprise, experience a 0% failure rate. There was also a 8 TB Seagate ST8000DM002 with a 0% failure rate, but the hard drive was only released in November.
The worst hard drives included WDC’s drives at 3.88%, followed by Seagate at 2.65%. It’s important to note how many hard drives Backblaze had. There were 1,626 WDC drives, and only 61 of those failed; there were 45,531 Seagate drives, and only 1,029 of those failed.
Backblaze used their experiences and they weren’t doing rigor testing. One could argue that real world data is better than final testing. However, there is no way to know how often the failed drives were accessed or whether an outside force caused their failure. Backblaze is in the enterprise business so they’d likely prevent temp swings or tampering. It is impossible to keep all the drives safe from outside forces.
While these aren’t consumer drives. It’s interesting to see what drives fail in data centers. I would avoid Toshiba hard drives, buy WDC branded ones, and maybe even buy Seagate. Parsing the data is a fun thing if you have a little extra time so read their whole blog post!
