Samsung QVO 8tb ZFS pool

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.

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.
what's the actual question?
- 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?
