As described in the title, my Convoy XL in RAID 1 with 2.5 500GB drives is giving me very slow transfers (max 3.6MB/s) on esata. This happened very recently, for no apparent reason. One thing that I notice is that during this file transfer, the Bay 1 and 2 LEDs both blink and alternate between red and yellow at the same time, something I've never seen before.

For the record, Steelvine says everything is fine and I have taken both drives out of the bays and ran SMART checks on them which found no errors.

Can someone help?
