nasready 312 and JBOD / no RAID setup
Hi, I'm thinking of buying a readynas 312 unit. I was just wondering can I install in it 2 different drives (a 4TB drive and a 8TB) and use them as 2 different btrfs volumes? Maybe I'm not using t...
Shouldn't be any problems, just disable xraid from the volumes tab, then create two separate volumes and you're good to go :-)
Edit; Not sure if the 312 can handle any 8TB drives though - on the official compatibility list there's only a 6TB drive, WD RED WD60EFRX.
If you are talking about the Seagate archival drive (ST8000AS0012), then you should know that:
(a) It might not fit into the disk tray w/o removing some plastic nubs from the tray (not sure)
(b) the sustained write speed of that particular drive is extremely slow.
It is designed for cold storage applications, not a NAS (and Seagate recommends against using it in a NAS). Some users have done it anyway, and some of them have reported back confirming the slow write speed.
IMO You are better off with a WD60EFRX.

Yep, which is the one with hardware encryption, and then the ST8000AS0002 which should be cheaper.
In case it would be just for storing movies (on a single disk volume, no raid), but not sure if it's a good idea like you said. Apparently also every scrub by btrfs may shorten the disk life.
Thanks for your help and informations!
I actually just found this thread:
If you run an excessive number of scrubs then it may shorten a disk's life. If you run scrubbing say every 2-3 months that's much more reasonable.
Scrubbing can only detect problems but not fix them if you are using JBOD / RAID-0.
