At the end of 2020, the comparable figure was 1.54 per cent and a year earlier the figure stood at 1.62 per cent. Nothing is just "objectively better" it's a different trade off. According to Backblaze, the lifetime AFR for all the drives in the table is 1.4 per cent, and continues to go down year after year. It's similar to how the linux kernel can be compiled with low latency in mind which causes lower throughput but makes the desktop experience much nicer (ime). This compares to the 2,200 SSDs that were covered in the March report.
This is not the only difference, but it's one thing to consider. Backblaze report finds SSDs as reliable as HDDs Toshiba reveals 30TB disk drive to arrive by 2024 Back up for a minute Backblaze HD reliability stats show oldies can be goodies As of June 30, 2022, there were 2,558 SSDs in the storage servers. This drastically improves the lifetime of the drives since they're slowly wearing down vs "going bad" because of a single block being unrecoverable. Backblazes 2018 hard drive reliability report has once again awarded the most reliable drive moniker to HGST hardware, with the lowest failure rate of all the companies tested. Sometimes what it comes down to is firmware WD NAS drives used to be almost identical to conumer drives except their firmware would report errors back to the SATA controller directly instead of continually trying to read the block.Ĭontinually reading the block seems doomed but it works a surprisingly large number of times, and when it's successful the block is often put somewhere else on the drive transparently (and the old block is marked as "bad"). Just to add: Consumer drives are not necessarily sub-par quality-wise just because they're consumer drives.

You can find the raw data here: At this point it goes back almost a full decade. Now, we do save (and publish) all the raw data, and some other awesome people out there have done various analysis on it, which always makes us happy also. If the reads and writes and seeks our drives experience matches your particular application, great! Or maybe it is just interesting to read. Sometimes readers think we're carefully running a "study", but it's more just what we have experienced as honestly as we can offer it up. We don't run any specific tests or induce issues on purpose FOR the drive failure stats, we just report what occurred in our datacenter. To be clear about what these drive failure stats are and what they are not: Backblaze runs a data storage service with about 214,000 hard drives in it right now. 'For the last four years, Backblaze has collected and reported on the failure rates and SMART stats of the hard drives in use in our data. > Is there a failure list for write heavy drives? Disclaimer: I work at Backblaze but more on the backup client side that runs on laptops, not in the datacenter storage side.
