![]() When BackBlaze measured the failure rate of its data center’s 4TB drives, it found that Toshiba drives failed most often, followed by Seagate. Moreover, the numbers were found when looking only at manufacturers and not taking into consideration different models and capacities. The company has also used consumer drives in an enterprise setup and has run those on a 24/7 duty cycle. It is said that the company has changed its storage pod designs, which might have impacted the reliability of a particular cluster of drives. However, Backblaze’s report is not perfect and has been subject to controversy. That makes it one of the best sources of information to find out the reliability of hard drives. The BackBlaze report provides good insight because it employs thousands of hard drives for storage. Source: Backblaze Shortcomings of the study You can find more details in the table below. After recording a quarterly high of five failures last quarter, they are back on track with zero failures in Q2 2021 and a lifetime failure rate of 0.41%. HSGT HUH721212ALE60 resides in Dell storage servers. The disk WDC WUH721816ALE6L0 has only been installed for three months, but no failures in 624 drives are a great start. With the one failure over the last year, this drive is aging quite well. According to both reports, we can conclude that Seagate ST6000DX000 and WDC WUH721816ALE6LO were the best performers in this competition.Īccording to Backblaze the average age of Seagate ST6000DX000 is over six years (74 months). These are Seagate ST6000DX000 and WDC WUH721816ALE6L0, the same model as in the first test, and then HGST HUH721212ALE600. Only three hard drives recorded zero failure. It is a bit higher than in Q1, but we should also consider that amount of tested disks was increased by 6016 drives. Backblaze tested 177,935 disks, and 439 failed, which is 1.01% of the overall annualized failure rate (AFR). The story was a bit different in the second test performed in 2021. In the table below, you can find an official report done by Backblaze. It had a 0.64% annualized failure rate (only five disks failed out of 3163). If you need a disk with less storage capacity, e.g., a 4TB disk, HSGT HMS5C4040ALE640 would be the best choice. We can conclude that these models performed very well and would be the best choice. Two disks recorded only one failure Toshiba MG07ACA14TA and Seagate ST16000NM0138. Four drive models recorded zero failures. Three hundred forty-eight hard drives failed, equaling 0.85% of the annualized failure rate (AFR).Īccording to Backblaze, this is a satisfying result considering the fact that they added 42,000 new hard drives to their farm and migrated another 23,600 drives over the period. In the first test performed in 2021, Backblaze did an observation on 171,919 hard drives spread across four data centers. The main testing criteria were lifetime failure rate and hard drive reliability. The capacity of tested disk drives goes from 4TB to 16TB, depending on the disk model.īackblaze conducted two tests in 2021. They’re somewhat slower than solid-state drive alternatives but offer a whole lot of storage. They are all known for producing high-capacity drives that compromise slightly on data performance. The most common hard drives tested by “Backblaze” are HGST (Hitachi), Seagate, Toshiba, and Western Digital. Backblaze releases reports every quarter and they are very much appreciated by the community. They took note of how many of its data center’s hard drives failed over the course of a year. Their core business is a cloud storage and data backup. A group of engineers and enthusiasts from the USA founded Backblaze in 2007. The challenge many end users face is choosing the most reliable hard disk drive from dozens of different brands and hundreds of different hard drive models.Ī study conducted by the cloud-based online backup tool Backblaze might help you to make the right decision. ![]() Any drive you buy today will fail eventually, but the more reliable your drive is, the longer you should be able to use it (though you should still be backing up your data regularly!). After all, when you’re choosing your hard drive, you’re deciding where and how to keep your data as safe as possible. Considering your priceless memories and career-enabling information can be stored on a single drive, you can probably benefit from a better understanding of different hard drive brands and what you can expect from them.
