SSD hard drives offer us many advantages over HDD drives . However, they also fail, although there are more and more models whose useful life is longer. Reliability on these drives has always been a problem, at least back when the first drives started coming out. Now, although it happens less and less, you still have to take into account which are the SSD models that fail the most.
In a report prepared by the cloud storage company Backblaze, which collects four years of data, it helps us to find out which models have been presenting the most failures. In this case, they are SSDs that they started using as boot drives in early 2018. And, data up to December 31, 2022 has been taken into account.
The SSD models analyzed
The report that Blackblaze has made gathers a large amount of information from the SSD hard drives that it has been using over these four years. So it gives us a totally different perspective on the durability and reliability of these particular components. In this report, up to 13 different models of different brands have been brought together:
- Crucial – CT250MX500SSD1 250GB.
- Dell – DELLBOSS VD 250 GB.
- Micron – MTFDDAV240TCB 240 GB.
- Seagate – ZA250CM10003 250 GB.
- Seagate – ZA500CM10003 500GB.
- Seagate – ZA2000CM10002 2,000 GB.
- Seagate – ZA250CM10002 250 GB.
- Seagate – ZA500CM10002 500GB.
- Seagate – ZA500GM10001 500GB.
- Seagate – ZA250NM1002 250 GB.
- Seagate – SSD 250 GB.
- WDC – WD BLUE SA510 2.5 250 GB.
- WDC – WDS250G2B0A 250 GB.
The disks with the most failures
Well, of these 13 SSD disks that have been used by this company from January 10, 2018 to December 31, 2022. Therefore, in that time, the annual failure rates (AFR) that have been giving these components. And of those 13 models, these are the 7 SSD drives that have failed during that time:
- Crucial – CT250MX500SSD1 250 GB: days used 107,449 – AFR 1.70%.
- Micron – MTFDDAV240TCB 240 GB: days used 67,511 – AFR 4.33% .
- Seagate – ZA250CM10003 250 GB: days of use 724,240 – AFR 0.66%.
- Seagate – ZA2000CM10002 2,000 GB: days of use 4,996 – AFR 7.31% .
- Seagate – ZA250CM10002 250 GB: days of use 568,911 – AFR 0.96%.
- Seagate – SSD 250 GB: days of use 132,535 – AFR 0.83%.
- WDC – WDS250G2B0A 250 GB: days of use 20,411 – AFR 1.79%.
However, a key point that should not be overlooked is that not all SSD drives that have been used by BlackBlaze have the same usage time, just as not all of these models have the same number of drives. So that also influences when it comes to seeing the percentage of AFR that each particular model has had.
In any case, we can see how, the model with just Seagate – ZA2000CM10002, with just 4,996 days of use (less than 5 days of use), already presented a fault with which its AFR rises to 7.31%, being the SSD that has the highest annual failure rate . On the other hand, the model with the most days of use, 594 days, without presenting a single error was the Seagate ZA500CM10003 SSD model with 500 GB. Therefore, there is a big difference between these 13 models. This company has not even been able to add to other models used in 2022, since they did not have the necessary data to find the annual failure rate.
