Raspberry Pi 4 powered USB3 hub

  • I've spent several hours trying to get OMV running on my Pi 4 with more than one HDD and eventually found out that the Raspberry Pi 4 doesn't play well with some powered USB hubs.
    Is anyone running OMV on a Pi 4 using a hub to connect multiple USB drives? If so, can you let me know the make/model of the hub please (I'm in the UK if that matters).

    There is a list on wikipedia but its a bit vague in places, hence my request here.

    Many thanks


  • I think it would be best to not use a USB hub at all. Instead use a USB drive or USB HDD enclosure that either does not need extra power or has its own power supply.

    Another option is to use a powered USB drive enclosure for several HDDs.

    I also only use UASP USB HDD enclosures.

    I have used a couple of Startech UASP USB HDD enclosures with RPi4 and OMV, and they all seem pretty good. I don't doubt that other brands can be as good or better. But I am satisfied with these.

    S3510BMU33 - powered 3.5" HDD UASP USB 3.0 enclosure.

    S2510BPU337 - unpowered 2.5" slim HDD UASP USB 3.0 enclosure. Nice for a 2.5 SATA SSD.

    S352BU33HR - powered dual 3.5" HDD UASP USB 3.0 enclosure. Easy to swap drives.

    Note: I don't have a USB hub between the enclosures and the RPi4. I suspect that if I did, performance would be degraded. Possibly severely degraded.

  • Thanks folks

    I've ordered that hub from Amazon UK - kinda annoyed that it costs the same as my Pi4 did but needs must.
    I get the point made by Adoby but this is supposed to be a low cost solution from bits I already have - which was everything except the PI.

    All the best


  • One advantage with a powered USB hub is that you can use it to power the RPi4 as well. That way you don't need to buy a separate power supply for the RPi. Saves money and makes for less cables and less clutter. You will need a USB A to USB C (charging) cable.
