If you thought really hard travel dependability and a galaxy far, significantly away could hardly ever be merged, you have significantly to understand. In honor of May well 4th, cloud backup enterprise Backblaze has launched its Q1 travel dependability final results, flippantly sprinkled with numerous references to Star Wars. In Q1 the firm monitored a full of 207,478 tough drives during its info facilities. Its report focuses on the drives nevertheless in use at that time, and also examines lifetime failure fees. As an example of how this is heading to go, it starts off with a Yoda quotation from The Previous Jedi: “The best teacher, failure is.”

In the newest study, the most resilient “senior” drive in the company’s storage pods is the 6TB Seagate ST6000DX000. Even though the firm only has 886 of them, none unsuccessful this earlier quarter. This is even with the drive’s ordinary age currently being about seven a long time. Which is an outstanding feat. In actuality, it is so superior Backblaze declares, “the power is strong with this just one.” Ugh. An similarly lengthy-working 4TB Toshiba design also suffered zero casualties in Q1, the MD04ABA400V. It has an normal age of 82.3 months. There are only 97 of all those buzzing absent in the pods even though. This design has only endured one particular failure for every 12 months, which is atypical.

As much as the “Padawan” drives go, aka the youngling generate, there ended up also various standouts. Backblaze takes advantage of three higher-capability Western Digital push types in its pods, and none suffered failures in Q1. Even so, they were all a short while ago set up. There’s a 14TB model that is a minor in excess of a 12 months old, and two 16TB designs that are just about manufacturer new. This can make it challenging to adequately evaluate their reliability in excess of time.

The corporation also introduced a new dependability visualization technique, proven earlier mentioned. It’s called the Travel Stats Failure Sq., and it divides all the drives in-use into 4 quadrants. The drives in the upper-proper (I) are the initial drives to be replaced when the time arrives. They’ve been running a extended time and are starting to experience failures much more typically. The drives in the leading-left (II) are the “winners.” They have been in the pods for a extended time and have small failure premiums. Going to the 3rd quadrant (III), these are the cocky youthful upstarts that are hoping to move into quadrant II just one working day. They are probably presently scheduling their Kessel operates. Lastly, quadrant IV is the “muddlers.” These drives should be changed but require to be monitored because they display screen unusual failure prices offered their age.

When it arrives to annualized failure rates (AFR), the company’s lifetime score for all its drives is 1.39 percent. This number is just .01 p.c reduce than very last quarter’s quantity. It’s element of an ongoing pattern with the organization that displays contemporary difficult drives are exceptionally trusted, and are very similar to SSDs in that regard. One particular year back the company’s life time AFR was 1.49 p.c, so push dependability is gradually improving upon more than time. Even though it’s a stretch, Backblaze titles this section of the examine, “You’ve failed me for the final time.”

At last, if you need just one drive to be your only hope, and just want to know which travel is the most dependable from today’s producers, in this article they are:

  • HGST: 12TB, model: HUH721212ALE600. AFR: .33%
  • Seagate: 12TB design: ST12000NM001G. AFR .63%
  • WDC: 14TB model: WUH721414ALE6L4. AFR: .33%
  • Toshiba: 16TB model: MG08ACA16TEY. AFR .70%
