Raid or Not for my configuration ?

1st Official Post

    Hello,
    I just bought a Rpi 5 with a specific board (Geekworm) to attach 2 NVME SSD Drive.
    I bought 2 SSD with 2To available on each.
    I just installed OMV on my SD Card (64Go) but actually did not install my SSD yet.

    I need to have your advice regarding method for installing theses two drives.
    I want to use them as Plex Server essentialy (maybe later I'll add a Docker Image for Python Django Node server but actually it's for Plex)


    So is it better to let theses drive without any raid for having 4 To spaces storage , configure a "Raid 1" to have one has backup ? or Raid 0 (for speed ... in this case I don't know If I will have 4 To spaces or only 2...

    Other question is it better to use btrfs, ext4 or ntfs for my configuration.

    Thanks for your help and advices

    This is the answer to your question. RAID is NOT BACKUP.


    Use one drive as your primary drive. Then use the second drive as your first backup using rsync, rsnapshot or borgbackup. Depending on your needs.


    Regarding filesystem: you cannot (or at least should not) use NTFS for daily use . It will cause you issues sooner or later.

    For BTRFS you need to learn a few things.


    Keep it simple and use ext4. If you ever feel the need to use one of the advanced features BTRFS is providing you can still switch.

    Thanks for your reply ! I'll read both articles you provided :) So Ext4 will be the best , and for Raid 0, 1 or no Raid I'll read your article and other post to know which is the best way for my needs (Nas Plex + Personal WebServer)
