Custom NAS advice

  • I'm putting together a custom NAS box from parts lying around with a goal of using it for file share, Plex or Emby, NZBs, torrenting and possible owncloud/nextcloud use. I'd like to use a USB to boot instead of buying an SSD plus allowing an extra drive, would using USB 2.0 have any impact on performance? What would be a ideal raid config? ZFS, Snapraid, or RAID5/6? Have to use an HBA because board have four SATA ports and only two are SATA III. Plus recommended plugins would be nice to know before jumping in to this. Looking for advice primarily and/or something I should watch out for.

    CPU - E3-1220v1
    Mobo - Intel S1200kp
    RAM - 16GB ECC RAM
    HDDs - 6 HGST 3TB
    HBA - Dell 310 flashed IT mode
    Case - Fractal Node 304
    PSU - 250-300 PSU

  • recommended plugin
    omv-flashmemory for usb boot
    usb 2.0 would affect long boot delay

    but I think ssd is better
    why? because you can install mysql for owncloud on ssd

    I recommend ZFS rather than linux raid
    because of bitrot protection, more flexible configuration, snapshot

    ZFS vs snapraid + union filesystem
    hmm it depends on..
    if you can buy multiple disks at once
    (2 for mirror, 3 for raid 5, 6 for raid 6)
    then zfs
    buy one by one
    then snapraid + union

    raid configuration
    3 disk raid 5
    6 disk raid 6
    all miror…fs-for-your-home-nas.html

    yeah many people says no raid 5
    but it is not bad acually
    there is debate for this topic reddit/datahoarder check about it

    no need to hba unless need more sata port since sata 2 alreday saturate hdd full speed

    OMV3 on Proxmox
    Intel E3-1245 v5 | 32GB ECC RAM | 4x3TB RAID10 HDD
    omv-zfs | omv-nginx | omv-letsencrypt | omv-openvpn

  • Thanks for input I do like Snapraid since I can add as I go, rather ZFS because of the costs mostly. I may go with an SSD for owncloud and better boot speed.
