Backblaze: Among Its 27,000 Drives, Hitachi Most Reliable

What are the most reliable hard drives? That's a question any computer user might ask, but when you own and heavily use 27,134 of them, as online backup provider Backblaze does, the answer is critical. In recent blog postings, the company has decided to share its findings from the last three years.

The top two brands used in those 27,000-plus drives are Seagate and Hitachi, with nearly 13,000 each, followed by Western Digital with about 2,800. Toshiba and Samsung are in the mix with a few dozen representatives each. One aspect to keep in mind, of course, is that Backblaze is using these drives more heavily than any single consumer or business would.

If it passes those hurdles, the model assumes a position on the buy list, which, when the price is right, triggers a purchase.

The company believes their incompatibility stems from a too-high vibration level in its storage pods, where the drives are housed.

Backblaze said that, "if the price were right, we would be buying nothing but Hitachi drives,"...
