  Hello,

  I just tried using the Sabrent 5-bay USB enclosure to create a RAID with 5 drives, but the speed was only USB 2 (~80 MiB/s). When I reduced it to 4 drives, the speed increased to about 200 MiB/s.

  Has anyone experienced a similar situation?

  Is this a limitation of USB 3.1, a Sabrent bug, or a host device issue?

  Thank!

  @paulajblanton 80 MiB/s is about double USB 2.0 but other than that, it's possible using all five bays on a daisy-chained controller could reduce performance.
