Could you comment a bit more on why you think this is so. I would
think that with modern processors and buses, a machine with light load
ought to be able to drive SATA-300, but I've never actuall tested for
I was off on my initial assumptions. I thought the "150" was 150 Giga-bit/sec,
or approx 15 Giga-byte, or 15000 MB/sec. Which is well above the PCI and other bus
speeds it needs to travel through to get to the processor.
But reading http://en.wikipedia.org/wiki/Serial_ATA it's 150 Mega-byte/sec. I think
older ATA chipsets are part of the PCI bus, which at 32 bits * 33MHz, which is about a
132MB/sec bottleneck. I don't know enough about PCI-X, PCI-E and newer chipsets to
know speeds & bottlenecks, so I'll just shut up now ;) But seems like > 100MBs
should be within reach.
