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
