Has anyone benchmarked this controller (PCIe/4x, 512 MB BBC)? We try to
use it with 8x SATA 1TB drives in RAID-5 mode under Linux, and measure
strange values. An individual drive is capable of delivering 91 MB/sec
sequential read performance, and we get values ~102MB/sec out of a
8-drive RAID5, seems to be ridiculous slow. Write performance seems to
be much better, ~300 MB /sec - seems ok to me.
I guess I must be doing something wrong, I cannot believe that a 500 €
controller is delivering such poor performance.
