Your SIL3132 again is a PCIe x1 device so should be fine assuming it has only one device and no port multiplier. Both should be running in AHCI mode, as should the ICH8R. 65MB/s for a 9 drives is a very respectable result.

April 10, 201016 yr This is in line with what I am getting also. I have a mix of 7200rpm and 5400 rpm drives. Thing is, all my drives are Seagate Barracuda 7200.11 1.5TB. No 5400RPM drive to slow down the array.
April 10, 201016 yr From my perspective, each drive added drops about 2Mb/s. 110MB/s peak is good for 80-90MB/s over the whole drive. Add 9 drives, -18 MB/s = 62-72MB/s across the whole array. A lot of people report their start performance not their syslog result. The people reporting above 80 MB/s tend to be three or four drive arrays. My array records 65MB/s, my seagate 50GB drives can only do 75MB/s and drag down the average probably 10-15MB/s, they are 7200 RPM drives, just old! I think this is good for nine drives. I'm guessing you have 9 1.5TB Seagates perhaps some other users can chip in with their performance figures across an entire parity sync?
