  1. Hello:

    Can anyone please tell the what the difference and advantages between parallel and serial ATA? I know it's kind of new and I've seen it advertised.

    Thanks so Much

    serial ATA is faster and the cables are smaller, so more convenient...

    I was just wondering what the terms serial and parallel mean. Are the sata's drives connected in series and the ata's connected in parallel? Was just wondering.

    Thanks for the quick response.

    it means that the data is passed serially. Thats a bit of a quick and dirty answer but its the most simple way to explain it without getting into technical details that might confuse some. though I'm sure someone will come along behind me and give you a webopedia copy/paste explanation. so I'll save them the trouble:

    Good post SB :) I knew what SATA was but that last quote was a good read to straiten facts out.

    Remeber though that the PCI bus is limited to 133MB/s

    So even if that SATA controller might work at 150MB/s the limit will be the PCI bus...

    The Intel ICH5 shoutbridge circumvents this by not being on the PCI bus... (it has it's own special bus...)

    And it's quite usefull with high-end harddrives because we really are getting limited by the PCI bus as it is now...

    Everything sits oin it, Soundcard, NIC's, Firewire, USB et etc etc...

    And run two harddrives in RAID-0 and you sure will max that PCI bus... (one harddrive can actually sustain 80MB/s if it's a new one....)

    Never mind the WD Raptor 10.000RPM harddrive...

    I was going to post a new thread about this, but I think it might fall nicely into this user's already existing thread... not trying to intentionally jack a thread.

    Is there any difference between SATA & SATAII. I have a SATA HD and I want to buy a new, larger HD but all I can find are SATAII drives. Will I have problems hooking up the SATAII drive?
