# BackBlaze's 'Statistical data by manufacturer and model 2022 Q1 version' that shows the HDD that demonstrates the best performance of each manufacturer will be released

BackBlaze, which regularly publishes statistical data on the failure rate of HDDs used in its own data centers, has released data for the first quarter of 2022 (January to March).

**Backblaze Drive Stats for Q1 2022**

BackBlaze was monitoring 211,732 HDDs and SSDs as of the end of the first quarter of 2022. Of these, 3860 are boot drives and 207,872 are data drives. This time, BackBlaze collects data from 207,478 data drives that meet the standards.

Below is the data for the first quarter of 2022. HGST's '

**HUH728080ALE604**' has the highest annual failure rate (AFR) of 24.31%. The average number of months used is 2 months, the number of units used is 76, and the cumulative number of days used is 4504 days. BackBlaze also pays attention to the fact that this model has a much higher annual failure rate than other HGST models. On the other hand, there are six models that maintain an annual failure rate of 0%: Seagate's '

**ST6000DX000**', Toshiba's '

**MD04ABA400V**' and '

**MG08ACA16TA**', and WDC's '

**WUH721414ALE6L4**', '

**WUH721816ALE6L0**' and '

**WUH721816ALE6L4**'. In particular, Seagate 'ST6000DX000' has a long-term average usage of about 7 years (83.8 months), but the result is that a total of 886 units did not fail at all in the first quarter of 2022. The 'ST6000DX000' has an annual failure rate of 0.11%

**in the 2021 annual statistics**, which is the lowest among all models.

Overall, the models by manufacturer that demonstrate the best performance recognized by BackBlaze are as follows.

・ HGST 12TB '

**HUH721212ALE600**' AFR: 0.33%

・ Seagate 12TB '

**ST12000NM001G**' AFR: 0.63%

・ WDC 14TB '

**WUH721414ALE6L4**' AFR: 0.33%

・ Toshiba 16TB '

**MG08ACA16TEY**' AFR: 0.70%

In addition to the above statistics, BackBlaze picked up and graphed HDDs that have been used for more than 1 million days since the first quarter of 2015 when data recording started. The vertical axis is the average number of months used, and the horizontal axis is the annual failure rate. BackBlaze evaluates the models classified in the 1st to 4th quadrants as follows.

・ First quadrant (upper right): Although this model has worked well so far, it is the most promising candidate for replacement given the current high annual failure rate.

Second quadrant (upper left): Proven to be reliable over time, you need to start planning a replacement over time, but don't panic

・ Third quadrant (lower left): Good start, no need to replace

・ Fourth quadrant (lower right): It needs to be replaced if possible, but it is not necessary to hurry if the annual failure rate maintains the current status. However, it wastes data center operational resources.
