What is the difference between ATA and IDE hard drive? Is one of them to prefer instead of the other or is it just about how they are connected?...

    I've successfully connected ATA harddrives and disc drives using both "IDE" and "ATA" cables, so for practical purposes I consider them identical. The same gray ribbon can connect either a CDROM or a harddrive.

    As for Serial ATA, that's a whole different animal. I like Serial ATA harddrives personally because the little SATA cables and their plugs take up a lot less space in my tower than the big gray ribbons. In theory SATA drives can run faster than IDE ones... but I've never had the money to buy a 10,000 or 15,000rpm drive to see.

    This may not be exactly what you're looking for, but here's a comparison of IDE/ATA and SCSI:

    Thanks. It was a good website, but it was mainly about the difference between SCSI and IDE/ATA. Now that I know a bit more about it, my question should be:

    What's the difference between serial ATA and IDE? Is it only the connection (you say it uses smaller cables) or are there any other differences?

    And are S-ATA drives always more exspensive than IDE drives with the same storage capacity?

    SATA drives are more expensive than IDE but it is not by a lot (usually as little as 5). iirc the early SATA drives were just ATA drives with a SATA bridge which didn't take full advantage of the technology, but now i think they are true SATA drives. it's almost all in the cable, which allows faster transfer speeds than ATA. i think SATA drives are just the same technology as ATA, with some changes to take advantage of the improved transfer speeds.
    Here's why Linux is easier than Windows:
    Package Managers! Apt-Get and Portage (among others) allow users to install programs MUCH easier than Windows can.
    Hardware Drivers. In SuSE, ALL the hardware is detected and installed automatically! How is this harder than Windows' constant disc changing and rebooting?
