It's a Western Digital Green 3 TB dating to May 2013.

I have rsync on that USB-stick installation of FreeBSD. I need to fear that any kind of write to that hard drive, even to restore the partition table, could push my data further to destruction if it's a hardware fault. > > After updating my backup with rsync, I could try to restore the GPT from backup at end of disk; I also found a backup copy of GPT data on the USB stick. > > Tom > > _______________________________________________ > freebsd-questions@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" My personal preference is WD Red (and NOT the Pro, just RED). It looks excellent on paper, and so far I have not had any failure on them (fingers crossed). The oldest I have is around 3 years old, used in a server, and zfs shows no data error. Drives I will definitely stay away from (at least for the next 5 years) is Seagate -- specially barracuda and the like. Lost several of them as they approached their 13th month life time -- similar use case (and sometimes even less). But I'm sure there are others in this list who has run extensive tests on HDDs and can recommend something better with practical data to back their findings. Hope this helps.
