Newegg.com just had a special on 750Gb Seagate SATA drives, so I thought it might be a good opportunity to replace my 400Gb IDE drives with ones that can be connected to the host by something less ghetto than IDE to USB 2.0 adapters. Who knows? I might even lash out on some kind of enclosure, instead of sitting them on cork trivets on top of the computer they're attached to.
So once the drives turn up, all I'll need to do is replace the PCI 4 port USB 2.0 controller with a PCI 4 port eSATA controller.
I'm a total SATA ignoramus, so if anyone has any suggestions on what's good, or what to avoid, shoot me an email.
