I would just like to share my experience with my 13 Seagate ST3000DM001 3TB SATA drives. In a word - shitty.
Informational preface:
The really AWESOME part is that one of the refurbished warranty drives started throwing SMART errors within DAYS of being resilvered into my pool. This fact likely screws with the above statistics somehow, but my brain is not in the mood to tackle that animal at this time.
Bottom line, if you are going to build a reliable NAS box, it is my opinion that you are best to steer clear of the ST3000DM001 drives. They may be really good $/GB, but they are not the best bang for the buck long term.
Finally, using Raid Z2 and a proper backup strategy has certainly reduced my anxiety due to these failures. Thanks to the FreeNAS team for providing a totally cool way for me to keep my data safe!
Cheers,
Informational preface:
- the maximum temperature EVER reported by smart has been 41C on one drive and 40C on some others with averages around 34C.
- The 41C temperature on one drive was reached when I had all 18 spinning drives in my system being scrubbed at the same time. This no longer happens as I fixed the schedule...
- scrubs are every 21 days for Raid Z1 backup pool and 28 days for Raid Z2 production pool and can no longer overlap
- Case has 6 80mm fans and good airflow
- server runs 24/7/365 in a room temperature environment
- 2 for failure to spin up after a a system shutdown (both in the last month when upgrading to 9.3)
- 5 for SMART errors (SMART still passed but Offline Uncorrectable Errors were increasing, scrubs did have to fix some errors at times)
