If a S-ATA controller embedded in the ICH5-R Southbridge of an Intel chipset
provides 150MB/s, and the M/B that contains that Southbridge offers two
S-ATA ports, is that 150MB/s on *each* channel or S-ATA port, or is it
shared between both ports?
Thank you.

100MB/s for each ATA channel and 150MB/s for each sATA port.
Nobody has tryed measuring totals when using more than two at once.

150 MB each. Not shared.

I thought we were at 133MB/s? ...or is that for PCI add-in cards?

Got it. So two S-ATA drives on each port, with a 60MB/s throughput in a
RAID 0 situation, would be a simple case of doubling and would result in
120MB/s?

Nobody has tried? Amazing.

Did they test 4 ATA drives, or a mix of 3+ ATA/SATA drives? Did they get over
120MB/s? |

|
2 ATA + 2 PATA. 200-220MB/s total.
The test is more to see what the MoBo chipset can do.
