I haven't really seen a post on this, and I know that BackBlaze posts their quarterly results, but they are running their stuff in a DC environment, and under climate controlled circumstances. As amateur storage enthusiasts, we are still not getting much consumer data on disk reliability, or reliability reports from our own personal environments, so I thought I would suggest this as a sticky, and start collecting some data.
Data points I think would be most useful to illustrate reliability:
Conditions disk is used in (Data Center, Home office, Garage, Shed, Etc.)
Manufacturer of disk
Model or Type (SAS, SSD, SATA, SCSI)
Size
Power On Hours
Max Temp
Power Cycle Count
My setup is in my garage, in the Florida heat and humidity. With the exception of 4 BRAND NEW consumer grade Seagates in 2014, which lasted all of 4 months in my garage before all 4 died, I can say from personal experience, I will never run anything but Hitachi HGST Ultrastar (SAS or SATA commercial) drives, as I have had 4 failures out of 33 disks, in 5 years. Also bear in mind these are HIGH HOUR drives I get off ebay as storage requirements grow.
I am running everything off of an R610 server, a Rackables SE3016 16 Bay JBOD, LSI 9207-8e HBA. I started with 7 x 1TB HGST Ultrastars, each had ~32k hours, and 4 new Seagates. 2 x 1TB HGST drives died, and all 4 Seagates died. I do not have any data from my first set, except the ~ hours and failure rate.
Following are some data points:
1st Set:
1. 13 x 1TB HGST Ultrastars (SAS), 4 x 1TB Seagate Consumer (SATA)
2. 52k hours when decommissioned
3. Max Temp ~110F
4. Failures: 2 HGST, 4 Seagate
2nd Set:
1. 11 x 2TB HGST Ultrastars, Model HUA722020ALA330 (SATA); 3 x 2TB Seagate, Model ST32000SSSUN2 (SAS)
2. Replacing, All between 66k and 67k hours. 1 pending failure prompted the replacement cycle.
3. Restart Count - Between 125 and 250
4. Max Temp 109F
5. 1 pending HGST and 2 Seagate
3rd Set (incoming replacement):
1. 6 x 4TB HGST Ultrastars, HUS724040ALA640 (SATA), 5 x 3TB HGST Ultrastars, HUS723030ALS640 (SAS)
2. Starting hours, 4TB disks 25k hours, 3TB disks, awaiting arrival
3. Restart Count - Between 40 and 50 for 4TB disks
4. Max Temp 109F
I will say, I am partial to HGST, since not only have they survived my torture chamber of a setup, but BackBlaze has the lowest failure rates from that brand. I am however seeing good stats on Toshiba as well in BackBlaze reporting, so they may be able to withstand my abuse as well.
Thanks guys, keep the data flowing!
