I just got my N5550 yesterday and had a lot of fun getting it set up last night. I love it, except for one key feature: all data transfers have been unexpectedly slow. I get around 4 MB/s, regardless of RAID configuration (I've tried JBOD, RAID 0 and RAID 6), connection protocol (I've tried AFP and SMB), or performance test (I've tried AJA, HELIOS, and just copying files and watching MenuMeters).
Does anyone have any suggestions on what I could try to improve performance?
I've done some searching and it looks like it's often caused by the disks in use. These are the four at my disposal:
Samsung HD103UJ, 1TB (Listed as supported on the compatibility list from Thecus)
(2x) WDC WD10EACS-00D, 1TB (Not Listed)
WDC WD20EARS-00S, 2TB (Not Supported/Recommended)
I tried just making a JBOD volume from the first disk only (the Samsung), but it still had the same transfer rates. Below are the results of my performance testing. All tests were done to an iMac wired using Cat6 to an unmanaged gigabit switch where both the computer and the N5550 are wired.
RAID 0 (Disks 1 and 2) over AFP:

Do I really need to go get 5 WD Red drives, or are there configuration things I could try?
