Hi all. I’m trying to choose a configuration for my home storage. Speed is not a priority, I want a balance of stability and performance. I was thinking of making a raid 6 array with an ext4 file system for 4 disks of 2 TB each. Asking for advice, will this configuration be optimal?

Note - I am going to make a raid array based on external usb drives, which I will plug into the orange pi

    Sounds like a plan. Only optimal if you situation calls for it. Some things to keep in mind, are is software or hardware raid. Also, backups out of this setup would be good. I like snapshotting, so that might be something you might want to think bout.

      Yeah, i am going to use off-site backup as well. Is snapshotting a thing in ext4 setup? don’t wanna go with btrfs, i heard that raid 6 with it goes bad.

          Yeah I’ve used lvm with snapshotting with great success. Raid is great, just remember it is only one measure for data retention. Another optional addition would be add a hot spare.

          That’s what I missed during my setup. I’m currently stuck without the LVM layer. With LVM, I think you can also theoretically add lvmcache and throw SSDs in front of your RAID array to act as cache, thereby improving the performance of your array. That’s another thing worth considering if you’re just setting up now.
