| technical question
I Have an old rig with an on board ide controller thats 66mhz,
So I decided to put an Pata 100mhz(ide)controller card in the rig,
And install the Os on the drive using the controller card 100mhz because it would utilize the Harddrive better being that the hard drive was ultra ata\ 133,(I didnt have a133 controller card  he he)
but anyways I was thinking...
Would putting the harddrive on the controller card make a difference because the controller card is a pci card.
Pci only having a bus of 33mhz. So would the harddrive get bottlenecked since now its on the PCI 32/33 bus. |

i dont think the controller will make any difference... a rig with an IDE controller @ 66mhz means that the CPU and ram arent very new either and the performance gain will be minimal

i could never get one of those pci cards to work to begin with.. i tried that on a rig i was building... instead of using the ones on the board i plugged the HD into the pci card IDE 1 and it never picked up the HD ... had to put it back onto the MB then worked fine... |

I know it wont make a huge performance difference, its an old athlon 800mhz but I'm more asking does the controller cards slow down the transfer rate to 33mhz because of the PCI bus being 33mhz. |

the pci bus can handle up to 133MB/s (or just under if you want to be pedantic  ), but that's shared bandwidth between all PCI devices. If the card is free to add then it'll probably speed things up a bit.

Alright thanks for the answer.....
Just for knowledge purposes if A sata1 (150)
controller was plugged into pci then it would be bottle neck down 133mbs right?? |

Yes that is correct. However, single hard drives are nowhere near transferring at 133Mbps, so the performance bottleneck is at the hard drive, not at the PCI bus or the HD controller. |

Yeah I read that before that why manufacturers say speeds up to 133mbs...
not to draw this out any further but. DanU you said "single hardrives" so in other words do you mean a RAID configuration could reach higher bus speeds |

you'll top 133Mbps with some RAID setups, or just having more than one hard drive transfering data at the same time through the bus i guess... |
