If you happen to thought arduous drive reliability and a galaxy far, far-off might by no means be mixed, you may have a lot to study. In honor of Might 4th, cloud backup firm Backblaze has launched its Q1 drive reliability outcomes, frivolously sprinkled with numerous references to Star Wars. In Q1 the corporate monitored a complete of 207,478 arduous drives all through its information facilities. Its report focuses on the drives nonetheless in use at the moment, and in addition examines lifetime failure charges. For instance of how that is going to go, it begins off with a Yoda quote from The Final Jedi: “The best trainer, failure is.”

Within the newest survey, essentially the most resilient “senior” drive within the firm’s storage pods is the 6TB Seagate ST6000DX000. Although the corporate solely has 886 of them, none failed this previous quarter. That is regardless of the drive’s common age being over seven years. That’s a formidable feat. Actually, it’s so good Backblaze declares, “the pressure is powerful with this one.” Ugh. An equally long-running 4TB Toshiba mannequin additionally suffered zero casualties in Q1, the MD04ABA400V. It has a median age of 82.3 months. There are solely 97 of these buzzing away within the pods although. This mannequin has solely suffered one failure per 12 months, which is atypical.

So far as the “Padawan” drives go, aka the youngling drive, there have been additionally a number of standouts. Backblaze makes use of three high-capacity Western Digital drive fashions in its pods, and none suffered failures in Q1. Nevertheless, they had been all lately put in.

This makes it arduous to adequately assess their reliability over time.

The corporate additionally introduced a brand new reliability visualization methodology, proven above. It’s referred to as the Drive Stats Failure Sq., and it divides all of the drives in-use into 4 quadrants. The drives within the upper-right (I) are the primary drives to get replaced when the time comes. They’ve been working a very long time and are beginning to expertise failures extra usually. The drives within the top-left (II) are the “winners.” They’ve been within the pods for a very long time and have low failure charges. Transferring to the third quadrant (III), these are the cocky younger upstarts which are hoping to maneuver into quadrant II sooner or later. They’re most likely already planning their Kessel runs. Lastly, quadrant IV is the “muddlers.” These drives ought to be changed however should be monitored since they show uncommon failure charges given their age.

On the subject of annualized failure charges (AFR), the corporate’s lifetime score for all its drives is 1.39 p.c. This quantity is simply 0.01 p.c decrease than final quarter’s quantity. It’s a part of an ongoing pattern with the corporate that reveals fashionable arduous drives are extraordinarily dependable, and are much like SSDs in that regard. One 12 months in the past the corporate’s lifetime AFR was 1.49 p.c, so drive reliability is slowly bettering over time. Though it’s a stretch, Backblaze titles this part of the research, “You’ve failed me for the final time.”

Lastly, when you want one drive to be your solely hope, and simply need to know which drive is essentially the most dependable from at this time’s producers, right here they’re:
