![]() 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. However, Klein points out that in the case of Seagate, most of the models from that vendor are significantly older than many others, and there is also the lifecycle cost of a given hard drive model versus its failure rate to consider.Backup company Backblaze has released it's hard drive data from 2017. Looking at a chart of annualized failure rates over time and by manufacturer, it might appear that much of the overall rise over the past year has been driven by Seagate and Toshiba models. Yes, it's true: Hard drive failures creep up as disks age.Backblaze thinks SSDs are more reliable than hard drives.New SI prefixes clear the way for quettabytes of storage.Barge off: Nautilus to bring floating datacenters to two new sites in US, France.This increase as a drive model ages follows the bathtub curve, whereby a typical drive can be expected to exhibit a rash of early failures, followed by a period when there are relatively few, followed by an uptick once more as all the drives approach the end of their lives and wear out.
