That directly correlates to how they were also the two drives with the most drive days. The Seagates suffered 13 and 15 failures over the four years, respectively.
Both drive families showed failures over time. This is also a meager 250GB SATA SSD with an AFR of 0.96% over 568,911 drive days. The third place on the podium goes to the Seagate ZA250CM10002. It suffered an AFR of just 0.66% over 1,104 drives running for 724,240 days. The runner-up is Seagate model ZA250CM10003, a 250GB SATA drive.
With 411 running for over 230,000 days, the failure rate was 0.0%. For that drive, BOSS stands for Boot Optimized Storage Solution. Of those three, the DellBOSS VD is the clear champion. However, only three drives have seen enough usage to give Backblaze confidence in their failure rates. For comparison, its lifetime AFR for hard drives is 1.39% (Opens in a new window). That's for all 2,096 drives since 2018, so pretty much what we expected in that they're very reliable. (Credit: Backblaze)Īs you can see at the bottom of the chart in bold, the overall lifetime annualized failure rate (AFR) is 0.89%. Lifetime failure rates for all 2,096 SSDs under Backblaze's control. One standout drive is an M.2 model mounted on a PCIe card, but the rest are SATA drives. The SSDs in its pods have the same workload too, making results directly comparable. In addition to booting the OS, they read, write, and delete log files all day. Also, the drives function like a consumer SSD as well. Despite the "server" environment, Backblaze uses 13 different consumer SSDs. The company uses them as boot drives in its storage servers. The report (Opens in a new window) shows the lifetime failure rates of 2,906 SSDs in use as of the end of 2022. Most of the SSDs fared quite well, with an annualized failure rate of less than 1%. This answers the question of whether they run cooler than HDDs.
It's also offering insight into the SSDs' operating temperatures over time. It's shown the failure rates of all its SSDs since it began using them in 2018. The company is using the longest reporting timeline we've ever seen this time. The interval of time it uses for its reports varies, as sometimes it's quarterly, annual, or both. Cloud backup company Backblaze has become well-known for its hard drive and SSD failure rate reports.
