I notice all these controllers are SATA III.
When I was struggling to understand why my new 4TB
HGST_HDN7240_40ALE_640 SATA III HD ;
couldn't seem to deliver a much  higher data transfer rate on SATA III
than on SATA II.;
one comment which was illuminating to me was;
" there is no such thing as a SATA III rotating hard-drive"
which I took to mean as :
' there is no rotating harddrive; whose heads  can transfer data on/off
the disk;
  at anything like 6Gb/s ~ 600GB/s' (SATA III max)'.
in contrast to say a SATA III SSD, where this is quite possible !
Apologies if this is merely repeating old news !
