Those drives are primary and secondary drives and stay on with the system 24/7.
Luckily, almost everything is backed up and the backups have backups so I didn't lose much.Īround 2015, I stumbled upon Backblaze's reports and saw that HGST and Toshiba's failure rates were pretty consistent.and low. I don't know what, if any, would have caused such failure rates, but they were high. That ratio almost evened out to 1:1 in 2012-3 as I was losing more Seagate drives in a 1 year period when compared to my WD's. Now as far as my subjective review goes (and this applies to only my experience and no one else's), Seagate prior to the Thailand disaster in 2011 were pretty decent and reliable drives. That being said, Backblaze does annual reports for hard drive failures. All drives will die over time, either by software failure or hardware failure. There's really no 'best' when it comes to hard drives.
