    Hi,
    I currently have 2 PATA hard drives installed in my system that both run off the same IDE ribbon cable. My MSI MS-7184 motherboard has 2 SATA connections and 2 SATA power supplies available. Would I benefit much by upgrading my hardrives to SATA ones? One of them holds the operating system and programs etc (160GB) and the other stores my mp3's (320GB). Would there be much speed gained or not enough for me to notice? Also would data be transferred faster if my PATA drives had one IDE cable each instead of sharing one? I seem to have 2 IDE connections on the motherboard.

    Depending on your specific usage, you might benefit from splitting the PATA drives between the controllers. IMO, you will not notice any difference replacing the drives with SATA drives assuming the rotational speed and disk buffer size is the same on the SATA drives as the PATA drives. Either ATA-133 or SATA-150 is far faster than the best hard drive mechanics can transfer data, so that's not the real bottleneck.

    You will not even notice any difference. The limiting factor is not the interface ie sata / ide, it is the physical ability of the disk to transfer info / data.

    If you are comparing like drives ie speed, cache, etc, there will be no difference in speed.

    If you plan to get another hard drive, for extra storage, get a SATA. But as already said, don't bother upgrading the PATA to SATA.
