Is this Seagate Exos drive too good to be true? (lemmy.dbzer0.com)

I found this its the cheapest 10TB Exos drive on Newegg and looking to buy 4 of them. I will be putting them in my NAS that I use for my media library and pc backups. The price I’m posting this is $130, I’m also looking similar Exos drives that are $250 is there a difference? Should I shell up for the more expensive drives?

It depends. They're simply the most annoying drives out there because Seagate on their wisdom decided to remove half of the SMART data from reports and they won't let you change the power settings like other drives. Those drives will never spin down, they'll even report to the system they're spun down while in fact they'll be still running at a lower speed. They also make a LOT of noise.

Aren’t they meant to go in data centers? You wouldn’t want a drive in a data center to spin down. That introduces latency in getting the data off of them.

That should be a choice of the OS / controller card not of the drive itself. Also what datacenter wants to run drives that don't report half of the SMART data just because they felt like it?

I have an Exos x16 and x18 drive and they both spin down fine in Debian using hdparm. I use them for cold storage and they're perfectly adequate.

Care you share your hdparm config then?

It's really boring, Debian 12: /dev/disk/by-uuid/8f041da5-6f7a-4ff5-befa-2d3cc61a382c { spindown_time = 241 write_cache = off }

[–] TCB13@lemmy.world 4 points 2 years ago

Tried that and doesn't seem to work. :(

Relevant documentation for others about -S / spindown_time:

Values from 1 to 240 specify multiples of 5 seconds, yielding timeouts from 5 seconds to 20 minutes. Values from 241 to 251 specify from 1 to 11 units of 30 minutes, yielding timeouts from 30 minutes to 5.5 hours. A value of 252 signifies a timeout of 21 minutes.
