Cloud backup service Backblaze has conducted another study of hard drive reliability, this time pitting consumer-grade hard drives against the more expensive enterprise-level disks. Over the span of three years, 4.2 percent of the consumer drives failed, while the enterprise drives suffered a 4.6 percent failure rate. The caveats are that Backblaze tested 14,719 consumer-grade drives against 368 enterprise drives, and the two sets were used for different purposes.
