    Are you buying the hardware for this setup, or do you already have it laying around? If you don’t have the hardware yet I’d recommend not using external USB drives in any way possible, as speed and reliability will be hindered.\n
    \n
    If you already have the hardware and want to use it I’m not super confident on recommending anything given my inexperience with this sort of setup, but I would probably try to use ZFS to minimize any potential read/write issues with dodgy USB connections. ZFS checksums files several times in transit, and will automatically repair and maintain them even if the drive gives you the wrong data. ZFS will probably be cranky when used with USB drives but it should still be possible. If you’re already planning on a RAID6 you could use a RAIDZ2 for a roughly equivalent ZFS option, or a double mirror layout for increased speed and IOPS. A RAIDZ2 is probably more resistant against disk failures since you can lose any 2 disks without pool failure, whereas with a double mirror the wrong 2 disks failing can cause a pool failure. The traditional gripe about RAIDZ’s longer rebuild times being vulnerable periods of failure are not relevant when your disks are only 2TB. Note you’ll likely want to limit ZFS’s ARC size if you’re pressed for memory on the Orange Pi, as it will try to use a lot of your memory to improve I/O efficiency by default. It should automatically release this memory if anything else needs it but it’s not always perfect.\n
    \n
    Another option you may consider is SnapRAID+MergerFS, which can be built in a pseudo-RAID5 or RAID6 fashion with 1 or 2 parity drives, but parity calculation is not real time and you have to explicitly schedule parity syncs (aka if a data disk fails, anything changed before your last sync will be vulnerable). You can use any filesystems you want underneath this setup, so XFS/Ext4/BTRFS are all viable options. This sort of setup doesn’t have ZFS’s licensing baggage and might be easier to set up on an Orange Pi, depending on what distro you’re running. One small benefit of this setup is that you can pull the disks at any time and files will be intact (there is no striping). If a catastrophic pool failure happens, your remaining disks will still have readable data for the files that they are responsible for.\n
    \n
    In terms of performance: ZFS double mirror > ZFS RAIDZ2 > SnapRAID+MergerFS (only runs at the speed of the disk that has the file).\n
    \n
    In terms of stability: ZFS RAIDZ2 >= ZFS double mirror > SnapRAID+MergerFS (lacks obsessive checksumming and parity is not realtime).

    Are you buying the hardware for this setup, or do you already have it laying around? If you don’t have the hardware yet I’d recommend not using external USB drives in any way possible, as speed and reliability will be hindered.\n
    \n
    If you already have the hardware and want to use it I’m not super confident on recommending anything given my inexperience with this sort of setup, but I would probably try to use ZFS to minimize any potential read/write issues with dodgy USB connections. ZFS checksums files several times in transit, and will automatically repair and maintain them even if the drive gives you the wrong data. ZFS will probably be cranky when used with USB drives but it should still be possible. If you’re already planning on a RAID6 you could use a RAIDZ2 for a roughly equivalent ZFS option, or a double mirror layout for increased speed and IOPS. A RAIDZ2 is probably more resistant against disk failures since you can lose any 2 disks without pool failure, whereas with a double mirror the wrong 2 disks failing can cause a pool failure. The traditional gripe about RAIDZ’s longer rebuild times being vulnerable periods of failure are not relevant when your disks are only 2TB. Note you’ll likely want to limit ZFS’s ARC size if you’re pressed for memory on the Orange Pi, as it will try to use a lot of your memory to improve I/O efficiency by default. It should automatically release this memory if anything else needs it but it’s not always perfect.\n
    \n
    Another option you may consider is SnapRAID+MergerFS, which can be built in a pseudo-RAID5 or RAID6 fashion with 1 or 2 parity drives, but parity calculation is not real time and you have to explicitly schedule parity syncs (aka if a data disk fails, anything changed before your last sync will be vulnerable). You can use any filesystems you want underneath this setup, so XFS/Ext4/BTRFS are all viable options. This sort of setup doesn’t have ZFS’s licensing baggage and might be easier to set up on an Orange Pi, depending on what distro you’re running. One small benefit of this setup is that you can pull the disks at any time and files will be intact (there is no striping). If a catastrophic pool failure happens, your remaining disks will still have readable data for the files that they are responsible for.\n
    \n
    In terms of performance: ZFS double mirror > ZFS RAIDZ2 > SnapRAID+MergerFS (only runs at the speed of the disk that has the file).\n
    \n
    In terms of stability: ZFS RAIDZ2 >= ZFS double mirror > SnapRAID+MergerFS (lacks obsessive checksumming and parity is not realtime).
