Apropos nothing (but possibly useful information)

I have a total of 12 HGST NAS hard drives that are between 6 1/2 and 7 1/2 years old. They all run 24/7/365.

Eleven of them are 4 TB; one is a 3 TB. The 3 TB and one 4TB are in my workstation. The other 10 4 TB drives are in my NAS.

None show any signs of aging or failure. One drive got kicked out of the NAS array about 2.5 years ago. I removed it from its hot-swap bay, and plugged it back in. It was recognized and rejoined the array. Other than that, there have been no incidents and no evidence of drive aging or failures. The NAS array is a RAID-6 and is scrubbed for errors once a week. No evidence of bit-rot (or if so, the scrubbing fixed it).

I would not have expected to go this long with zero failures. But I have. So, if you are looking for reliable drives, might want to look at HGST NAS drives.

Did you check SMART status and run HD tests? I use GsmartControl for that.

Yes, of course. Given their age, monitoring their status has moved up my priority list and I look at them frequently.

So they appear healthy! Good. I guess 24/7 helps to reduce startup stress significantly. I had some old HDs and I had one dying just months before warranty ended. For now no significant loss as I have multiple drives copies.

A tip on the subject:

I have rescued the data from one SSD and one CompactFlash, by heating them in a box and keeping them there while reading. They were stone dead when at room temp, not even present to BIOS. The SSD needed only 40C, the CF 70C.

So if you find yourself needing to get data out of a dead storage device, try to heat it, and if that fails, try to cool it.
