It make no sense today for me anymore…I found more downside than real use of my RAID5 array.

My setup: 5 disks of 22TB in Raid 5

  • Data Organising is estimated to 20 days!
  • Rebuild time of RAID5 is unknown never had to do (yet) :-)
  • Disks never sleep in BTFRS, power cost is here 0.30 per kWh
  • Constant noise of 5 disk clicking instead of only one or two when using
  • Do I need 80TB of continuous stiorage? Not really with 2700 movies= 12TB, 8000 TVShow episode= 14TB, most is still in h264 few in h265 and really really few in AV1 (fantastic by the way)
  • I dont care about Media, and rebuild everything on a 10GB Fiber most of it automatically. Most of my private stuff is on 3-2-1 encrypted anyway
  • High availability is not a topic, I’m alone using this box. And even, my Homelab is best effort not 24/7

I have another NAS full SSD, with 8 SSD but I hate the nature of RAID in SSD: they die unexpected most of the time. I prefer to lose 4TB then put 30TB at risks if 2 or more SSD decide to stop working

So maybe duplicating on another disk in a mirror (rsync) is maybe better for me

      dont need uptime… tried truenas scale on my ugreen nAS 64GB RAM (no ECC) and did not like it. ZFS is great no question but learning curve and risks of losing my whole array is too high (or two array of ZFS2). A pure EXT4 JBOD with replication once in a while is enough and more energy efficient for media

      Anyway I envision to keep updating most of it to AV1 down the line, so reducing storage need over time (long period)

        RAID (any form of it) is an uptime technology. If you don’t need uptime, you don’t need RAID
