(Credit score: Backblaze)Cloud backup firm Backblaze has turn into well-known for its laborious drive and SSD failure fee reviews. The interval of time it makes use of for its reviews varies, as generally it’s quarterly, annual, or each. The corporate is utilizing the longest reporting timeline we’ve ever seen this time. It’s proven the failure charges of all its SSDs because it started utilizing them in 2018. It’s additionally providing perception into the  SSDs’ working temperatures over time. This solutions the query of whether or not they run cooler than HDDs. Many of the SSDs fared fairly properly, with an annualized failure fee of lower than 1%.

The report exhibits the lifetime failure charges of two,906 SSDs in use as of the tip of 2022. The corporate makes use of them as boot drives in its storage servers. Regardless of the “server” atmosphere, Backblaze makes use of 13 completely different client SSDs. Additionally, the drives operate like a client SSD as properly. Along with booting the OS, they learn, write, and delete log information all day. The SSDs in its pods have the identical workload too, making outcomes immediately comparable. One standout drive is an M.2 mannequin mounted on a PCIe card, however the remainder are SATA drives.

As you’ll be able to see on the backside of the chart in daring, the general lifetime annualized failure fee (AFR) is 0.89%. That’s for all 2,096 drives since 2018, so just about what we anticipated in that they’re very dependable. For comparability, its lifetime AFR for hard drives is 1.39%. Nevertheless, solely three drives have seen sufficient utilization to offer Backblaze confidence of their failure charges. Of these three, the DellBOSS VD is the clear champion. For that drive, BOSS stands for Boot Optimized Storage Resolution. With 411 operating for over 230,000 days, the failure fee was 0.0%.

The runner-up is Seagate mannequin ZA250CM10003, a 250GB SATA drive. It suffered an AFR of simply 0.66% over 1,104 drives operating for 724,240 days. The third place on the rostrum goes to the Seagate ZA250CM10002. That is additionally a meager 250GB SATA SSD with an AFR of 0.96% over 568,911 drive days. Each drive households confirmed failures over time. The Seagates suffered 13 and 15 failures over the 4 years, respectively. That immediately correlates to how they have been additionally the 2 drives with probably the most drive days. Many of the different drives with a 0.0% failure fee (Dell apart) both haven’t been operating lengthy sufficient, or there aren’t sufficient drives to offer them confidence of their longevity ranking.

Backblaze additionally checked out drive temps all through 2022. So far as we will recall, this can be a first for the corporate. Notably, the chart’s Y axis begins at 34C and ends at 36C. In different phrases, not a lot to see right here, of us. The drives stay cool, and that hardly modifications. The report exhibits the drives modified by one diploma Celsius all 12 months, from 34.4 to 35.4. Apparently Backblaze says the common temperature of its HDDs is simply 29C. Nevertheless, it thinks that is as a result of placement of the drives within the system. Its pods stuffed with laborious drives obtain the cool air first, so the SSDs are left to fend for themselves. It doesn’t point out if there’s any cooling directed on the SSDs, however given the temps, it looks like it doesn’t matter.
