Would be nice to see the range of performance for that drive after the firmware update.

PCI bus bandwidth is 133MB/s, which is less than SATA I, so there would be no point in a PCI SATA-II controller.

actually the PCI bus bandwidth is 133MB/s with 33Mhz on a 32bit bus, but with 66Mhz on the same 32bit bus it is double (266 MB/s). If you have a 64bit bus it is even bigger (double again).
66Mhz was introduced with PCI 2.1, my MB has 32bit bus and it supports PCI 2.2 so I should be ok.
here are some facts about PCI 2.1, according to wiki:
PCI 2.1, released on June 1, 1995, allows for 66 MHz signaling at 3.3 volt signal voltage (peak transfer rate of 533MB/s), but at 33 MHz both 5 volt and 3.3 volt signal voltages are still allowed. It also added transaction latency limits to the specification.http://en.wikipedia.org/wiki/Conventional_PCI# cite_note-6
btw, I already found the controller and ordered

Palerider's sequential read results are correct, unfortunately. He/she is bus-limited with a 33 MHz bus. I have the same problem with my Intel D620 laptop with an old Dell-implemented ICH-7 southbridge. Time for a new machine one of these days....

This is a G2 80GB running 02HD.
4K's seem kind of low compared to the rest of the thread. This is installed as the primary in a Gateway P6860FX (http://support.gateway.com/s/Mobile/2008/GodzillaFX/1015340R/1015340Rsp2.shtml http://support.gateway.com/s/Mobile/2008/GodzillaFX/1015340R/1015340Rsp2.shtml) laptop running Win7 x64.
Any idea what's holding me back?
Thanks!
