Do SSD failures follow the bathtub curve? Ask Backblaze
The Register, Tuesday, September 26,2023
Cloud-based storage and backup provider Backblaze has published the latest report on usage data gathered from its solid state drives (SSDs), asking if they show the same failure pattern as hard drives.
Backblaze uses SSDs as boot drives in the server infrastructure for its Cloud Storage platform, while high-capacity rotating drives are typically used for storing and serving up data.
However, they do more than just boot the storage servers, holding log files and temporary files produced by each server. The volume of data a boot drive will read, write, and delete thus depends on the activity of the storage server itself.
The company previously reported that its SSDs appeared to be at least as reliable as hard drives, but warned this could change as it has not collected SSD data for as long as hard drives and the accumulation of more data could alter the statistics.
