using only external USB drives for storage space

  • Hi,
    really noob question.. sorry in advance!


    With all the thin clients, cheapest nuc boxes available, would it possible to install OMV in it and use external USB drives for storage in order to quickly build a relatively cheap 1 or 2 drives NAS?
    I'm not sure how reliable the USB bus could be.. but in case of a drive fail there are some pretty cheap replacements out there.. and even if won't look as the neatest of the setups, having to swap drives without open the enclosure has its appeal.


    Thanks for any suggestion

  • I don't see why it couldn't be done. You might see some speed differences on some things, due to the speed differences between the USB bus and the normal internal SATA bus. The only other issue I could see... is if for some reason the NAS is powered off.. you'd want to make sure the external drives are turned on (ie, external power source) before turning the machine on. Otherwise, the machine will eventually boot, but I believe it would complain about missing file systems, services probably wouldn't start properly, etc. If the external drives were not on prior to when you booted the machine, turn on the drives, log into the webUI mount the external file systems, and *probably* (not sure on this part) restart any service that uses the data that is on the USB drives (ie, SMB, Plex, etc..)


    So can it be done? Yes. Is it practical? Not really... just get a cheap case and put the drives inside the case on the SATA bus.

    Air Conditioners are a lot like PC's... They work great until you open Windows.


  • Just get something with USB 3 (note that the Celeron NUC only has one USB3 Port) and you'll be fine...

    Well, that is way more expensive then the setup he has on his mind I guess.

    Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.

    There are of course differences, but you will reach the limitations of a single gigabit network link long before the throughput of an USB3 or SATA link reach their limits. So that doesn't make a difference in terms of usability of a NAS.
