A study conducted by cloud-based online backup tool BackBlaze might help you make that decision. Backblaze took note of how many of its data center’s hard drives failed over the course of a year.
It found that Western Digital’s drives were overall the least reliable.
This comes as a big surprise considering Western Digital is a hugely popular brand among PC enthusiasts and mainstream users alike. BackBlaze’s findings are relevant to businesses and average consumers alike in that the cloud-based storage company uses the same typical, off-the-shelf products that regular consumers use.
The analysis officially released by the company states that during
2015, BackBlaze used over 56,000 hard disk drives which were in turn organized into 1,249 storage pods. The drives were of various capacities, some storing only 1 TB while others stored up to 8 TB. The only hard drive manufacturers used by the company were
HGST, Seagate, Toshiba, and Western Digital.
The hard drives failed differently depending on their make, model and capacity, but the difference based on manufacturer was substantial. HGST was the most reliable of the hard drive providers and had an annual failure of only 1 percent. Toshiba had an annual failure rate of nearly 3.5 percent, Seagate ranked in at slightly more than that but still under 4 percent, and
Western Digital topped the charts at just under 7 percent.
