My omv setup has 8 Hard Drives (7200 and 5400) with good transfer rates (+90 to +100 MB/s WRITE). (tested with HELIOS LAN Test)
FYI: All of those Hard Drives where external 3.5" HDD in an enclosure.
I dislocated those Hard Drives and put them into an 8 bay enclosure.
However 2 Hard Drives, when put into the same enclosure, have poor transfer rates (10 MB/s).
(Those drives have also been external ones that I extracted from their case.)
I switched their places in the enclosure many times to make sure that its the disks and not the SATA connectors of the enclosure that cause the low transfer rate.
With those 2 drives HELIOS LAN test did't give me any readings but a spinning wheel.
The 10 MB/s where displayed during the copying of files (via SAMBA share).
I've copied OMV's SMART extended info from the 2 slow drives and from one of the fast drives (full info is in the attached txt files):
