    Hi
    Is it possible to just have a Synology NAS with no RAID (or SHR) options?

    I have two 8TB drives in a NAS and backups are going to be kept on external hard drives.

    When I go into RAID Type I see SHR (Synology Hybrid RAID) and the two drives and it's saying available space is roughly 7TB. I'd like to see 14TB :)

    I click Manage on the Volume and Change RAID Type is greyed out.

    Thanks
    M

    Got it. RAID0.

    A striped volume (RAID0) is quite risky!
    If one drive fails that’s all your data gone

    16TB RAID0 is kinda fault prone alright.

    I'd go for JBOD and software pool them together.

    You can delete the current volume and set up two separate volumes instead. Back up any needed data first.

    What is "fault prone" about RAID0?

    A fault on either drive = 16TB loss

    With 2x 8TB Volumes, A fault on either drive = 8TB loss

    Basically you are increasing your risk of dataloss with RAID 0 for no gain.

    Also if they're SMR drives then the odds are potentially increased again.

    Thanks for that - I wasn't aware of SMR Drives before. Archive Disk is the best description I could use for them. Write Seldom, Read Often.

    It's called Raid 0 because that's the exact number of files you'll recover if any drive has a fault.

    Note
    since filesystems like NTFS put small files in an $MFT area you probably won't recover files below the stripe size either.

    If you just want to see all the folders from both drives in one listing, you could use Libraries feature in Windows.

    But you probably doing something else entirely.
