In reply to Andy Klein. Hi Andy, I was curious why some drive models, such as ST1500DL003, did not fail but are no longer getting updated. For example, after 2015, the ST1500DL003 drive models are no longer updated with additional data. Did you just pull these drives out even though they were still running?

Thank you so much. I’m currently in the market for a new backup drive, external if possible but the HGST drives seems to be the most stable. Amazon has them but all internal. I do have a nice external enclosure so it’s not a big deal. Thanks again!

Hi Backblaze. As a reliability engineer i found this page whilst looking for a different study. The conclusions of the study i am looking for discovered that the annual failure rate increases with time over a fixed population. Censoring data and grouping it into annualised averages is not a useful approach due to the presence of failure modes related to age as opposed to random probability of occurrence. As such, your data would be good to observe if it could be arranged in this way. i.e. knowing times to failure for each drive. An average annualised rate hides this information and makes it difficult to separate brands, which i believe is the intent.

I am going to stay with WD drives, the Seagates look scary. But the new
HGST drives look interesting.

In a long period of time all drives even the most reliable will break. All values are scrambled. This chart makes no sense.

Seagate drives: I expected failure rated like that based on the high(96%+) failure rate of these drives. I have a Seagate about to die, trying to get data off of it and it’s quite slow. Errors left and right, and SMART stats are worrying.

In reply to AZZAZ RACHID. Have you completed this yet? I would love to see your findings.

So with the data above what would you say is the number one drive that is on the market to date?
