![]() failed CBA and they use consudmer drives.īlackblaze aren't the first to come to this conclusion either. The differences are so small that being "engineered for high vibration blahb blah blah" is just B.S. When the drives get tested side by side in the real world. They are virtually all the same hardware with a few tweaks to firmwares and then sold at 5x the price with mostly marketing buzz words thrown in to fool the idiots. The HDDS are not made to some ridiculous "survive in space" conditions. ![]() But the hardened drive will have reasons for its usage.Ī tank cant be compared to an SUV.but we do.Ĭlick to expand.But this is what you are inccorectly making assumptions on. If backblaze is going to have to pay over 8K more for a drive specifically for a server environment I can see how the ordinary drives is a better option. I still, even with this example feel that the expectation of a drive being in an environment that is 'not' consumer will perform better. So there are comparable's to a basic drive and one 'manufactured' to be in high stress environments. Maintenance guy drove to walmart and bought a seagate drive.įrom backup, copied data and we put it in the microscope. Once the drive was in my hands, it was a simple scsi drive. Maybe as simple as adding a gasket of rubber between the metal to metal contact points.Īs much as I dont want to remember, I remember when I had to buy a scsi drive for a failing one in a electron microscope.overnight. A consumer drive isnt expected to have to perform in the same environment. Along the way we'll share observations and insights on the data presented and we look forward to you doing the same in the comments.īut a drive that is expected to be in a high vibration, high heat environment will be engineered to be there. We'll review the stats for Q4 2017, all of 2017, and the lifetime statistics for all of the drives Backblaze has used in our cloud storage data centers since we started keeping track. This post looks at the hard drive statistics of the data drives we monitor. Of that number, there were 1,935 boot drives and 91,305 data drives. ![]() Currently Backblaze has 91,305 data drives in operation, crazy.Īt the end of 2017 we had 93,240 spinning hard drives. Because of the infrastructure Backblaze has built up it gives a great look into the reliability of these hard drives in a fairly harsh environment. I look forward to this report every time. One thing that has been true year after year, HGST drives are pretty reliable. During Q3 and Q4 Backblaze removed nearly all the 3TB drives it had in service, and began installing 10TB and 12TB drives in their place. He pointed out the drives do more than just boot the servers, they also store log files and temporary files produced by the servers, and so each SSD will read, write, and delete files depending on the activity of the server during the day.Backup company Backblaze has released it's hard drive data from 2017. In a blog post detailing the latest probing, Backblaze cloud storage evangelist Andy Klein said the SSDs are all used as boot drives in the firm's storage servers, and that Backblaze only began using SSDs this way from Q4 of 2018. The 2021 Drive Stats report was published in February. Backblaze said it will initially publish the SSD edition twice a year, but that this may change depending on how valuable readers find it. The cloud storage and backup provider publishes quarterly and annual Drive Stat reports, which focused exclusively on rotating hard drives until last year. Backblaze has published the first SSD edition of its regular drive statistics report, which appears to show that flash drives are as reliable as spinning disks, although with surprising failure rates for some models.
