We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

Samsung QVO 8tb ZFS pool (alien.top)

Hey everyone. I have a nice unraid server with sas drives and with plex I find that my kids and wife watch the same stuff all the time. I spin down my sas drives to keep power consumption down but at the same time the lag to start them up is annoying as well as I don’t to cause extra wear and tear on the drives by having them spin up and down multiple times a day.

So I was thinking about buying 3x Samsung QVO 8tb drives and firing up a ZFS pool and moving stuff they watch all the time to there. that would speed up reads and reduce wear and tear on the drives.

For backup I rotate externals for critical data every week in and out of my fireproof safe with two 4tb external usb. Our media storage I have a second unraid server that starts up every Saturday and rsyncs from primary and powers off.

what's the actual question?

[–] Cerusa827@alien.top 1 points 11 months ago

Any downsides or pitfalls I should be aware of before I spend a grand? I know the drives are not stellar for write performance past a point. I know unraid supports trim in pools as well.

Okay, have fun?

One ZFS drive per pool, with unraid on top? Should be mostly fine. As you say these drives are terrible for writes, but they should be pretty reliable and performant for your workload.

I would do a single ZFS pool with the three drives.

Electric is 35 cents per kWh here

that would be ideal

So if you have 6 SAS drives running 24/7 the turnover point from this investement would be at roughly 5 years. IMO not worth it at all.
