    some site sell 80pins with 68pin adapters. I freaking love my scsi drive, one of the better things I have bought, but this happy hacking keyboard might just be equally good:

    Like pudad said, drives with 80-pin connectors are designed to be used with hot-plug backplanes. The 80-pin connector includes the same data carrying capabilities as the 68-pin ribbon cable, but it also includes pins for powering the drive and setting the SCSI ID.

    If you have an 80-pin drive but aren't using it with a hot-plug backplane, you'll need an adapter so that you can use a 68-pin cable.

    I gues guess the question now is which is more expensive, 80oin cable or 68pin cable and converter, but I doubt this guy has scsi since he considers him self a scsi newbie

    It varies, since it's sort of a supply vs. demand thing. Sometimes you can find great deals on certain 80-pin models because there are more of them in the supply chain than needed and they'll sell 'em cheap just to get rid of surplus. Most of the times I'm looking for an 80-pin drive, the particular ones I need aren't cheap, though! (Go figure.)

    Not at home -- I'm a network admin and most of our servers run hot-swap drives.

    A GOOD 80 to 68 pin converter will run about $30, so unless one is buying the 73gb+ sized drives, its a big difference. I'm running an 80pin Seagate X15.3 with a converter, but I had no choice since I needed the drive asap when it came out and they didn't make the 68 pin version. I definitely wish I had waited as the converter is a bit of a pain to deal with.

    yeah I have only messed w/ 68, but a lot of places pack the converter with the drives. but I don't know what is considered good.
