Who makes the most reliable hard drives? Personally, I am a fan of WD's 4TB enterprise drives. Which brand have you had the best luck with?
All the drives are "consumer grade" rather than "enterprise" drives, because enterprise drives are more than twice the price. Backblaze says: "Even if there were no warranty, a 15 percent annual failure rate on the consumer 'desktop' drive and a 0 percent failure rate on the 'enterprise' drive, the breakeven would be 10 years, which is longer than we expect to even run the drives for."
