Hey everyone. So I’m trying to decide which RAID should I choose for my 6trays NAS. I have 4 x 16TB HDDs, 1x8TB HDD and another one 500GB ssd that I will use as a containers’ docker folder usage. I will be using the NAS to store Media files (movies, tv series, photos, music etc.) and also documents. Currently I have the 2 16tb as RAID 1 that only the Media files are stored and I am in between either creating another RAID 1 with the remaining 2 16Tbs or adding them to the other 2 to create a RAID 5 and have a bigger storage pool
Have you had any incident where 2 HDDs were lost-damaged simultaneously (as RAID 5 forgives loss of only 1 drive) or not?
In addition I was thinking of having the 8TB HDD as a standalone to backup the documents and maybe the photos and the docker setups.
Does this make sense to anyone that uses similar setup?

Use zfs, raid 10 the big drives, toss the 8tb, and use the ssd as a write cache.
This is the way to go. Way more flexible than hardware raid and getting better all the time.
In ZFS-speak, instead of RAID 10 you’ll be doing “mirrored vdevs”
Interesting take. I have them setup in BTRFS and use 2 m2 nvmes as read write cache in RAID 1.
