Description:
While HDD reliability scores continue to deteriorate, SSDs are holding their ground as a firm favorite.

FULL STORY ======================================================================

Cloud storage and backup company Backblaze, which has become synonymous with its regular SSD and HDD reliability tests, has just announced new figures
that will make very pleasant reading for most users.

This time, the company approached its report by mulling over the statistics
of the first six months of 2023, making it the most up-to-date study we have on the state of the market.

With 3,144 SSDs in its storage servers, the figures have also become more reliable compared with last years end-of-year report, when the company had 2,558 SSDs on its books. SSDs continue to be reliable

Cross-referencing the number of drives it has with the number of failures experienced, alongside other factors such as device age, allows Backblaze to produce what it calls annualized failure rates (AFR).

The second quarter of 2023 saw SSD AFRs climb to 1.05%, up from 0.96% during the first three months of the year. In reality, these figures are no cause
for concern, with 2022s AFR standing at 0.98% for the year, and 2021s AFR coming in at 1.05%.

Even so, the companys SSD reporting remains slightly less reliable than the figures it produces for HDDs purely on the basis of having fewer SSDs. Backblaze said it like[s] to see at least 100 drives and 10,000 drive days in a given quarter as a minimum before [it] begin[s] to consider the calculated AFR to be reasonable.

Of the 14 different SSD models it uses, only four (29%) meet these criteria, with two others falling just short of the ideal minimum number of days. By contrast, 26 of the 29 HDDs on Backblazes books, or 90%, met the criteria.

In reality, the latest figures arent too dissimilar from Backblazes lifetime AFRs. Since it has been ranking SSDs in 2018, their AFRs have averaged out at 0.90%.

What it does show is that SSDs have favorable reliability scores to HDDs,
with the latter experiencing growing AFRs annually to the point that, by the end of 2022, HDDs had an AFR of 1.37%. More from TechRadar Pro Thinking of upgrading?
