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.

| 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.

Then consider c't to be a nobody.

I thought we were at 133MB/s? ...or is that for PCI add-in cards?
...and 150MB/s for each sATA port.

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.
