If you think you can’t combine the reliability of a hard drive with a galaxy far away, there’s a lot to learn. To commemorate May 4, cloud backup company Backblaze announced the results of its first-quarter drive reliability, lightly sprinkling various references to Star Wars. In the first quarter, the company monitored a total of 207,478 hard drives across the data center. The report focuses on the drives that are still in use at that time and also looks at lifetime failure rates. As an example of how this goes, it begins with a Yoda quote from the last Jedi: “The best teacher, failure is.”
In Latest surveyThe most elastic “senior” drive in the company’s storage pods is the 6TB Seagate ST6000DX000. The company has only 886 companies, but none have failed this quarter. This is despite the average age of the drive over 7 years old. It’s an impressive feat. In fact, it’s very good that Backblaze declares “this is powerful”. Hmmm. Similarly, the long-term 4TB Toshiba model had zero casualties on the MD04ABA 400V in the first quarter. It has an average age of 82.3 months. However, only 97 people are humming in the pod. This model fails only once a year, which is not common.
As far as the “Padawan” drive, also known as the Young Ring Drive, there were some outstanding ones. Backblaze uses three high-capacity Western Digital drive models for its pods, none of which failed in the first quarter. However, they were all recently installed. There are two models, a 14TB model a little over a year ago and a nearly new 16TB model. This makes it difficult to properly assess long-term reliability.
The company also announced the new reliability visualization method described above. This is called the DriveStats Failure Square and divides all the drives in use into four quadrants. The drive in the upper right (I) is the first drive to be replaced when the time comes. They have been running for a long time and are beginning to experience disabilities more often. The drive on the upper left (II) is the “winner”. They have been in pods for a long time and have a low failure rate. Moving to quadrant 3 (III), these are cheeky young start-ups hoping to move to quadrant II someday. They are probably already planning to run Kessel. Finally, Quadrant IV is “Muddler”. These drives need to be replaced, but should be monitored as they show anomalous failure rates over time.
In terms of annualized failure rate (AFR), the company’s lifetime rating for all drives is 1.39 percent. This number is only 0.01% lower than the previous quarter’s number.This is the latest hard drive Very reliable, And in that respect it is similar to SSD. A year ago, the company’s lifetime AFR was 1.49%, so drive reliability has gradually improved over time. It’s not straightforward, but Backblaze has titled “You made me fail in the end” in this section of the study.
Finally, if one drive is your only hope and you want to know which drive is the most reliable from today’s manufacturers:
- HGST: 12TB, Model: HUH721212ALE600. AFR: 0.33%
- Seagate: 12TB model: ST12000NM001G. AFR 0.63%
- WDC: 14TB Model: WUH721414ALE6L4. AFR: 0.33%
- Toshiba: 16TB model: MG08ACA16TEY. AFR 0.70%
