ultra scsi

I have a G3/350 now, but for college I plan on having either a G3 or G4 400 or 450

umm... are you talking about dv or analog video editing? dv video comes into the machine at around 3.6MB/sec. analog comes in much quicker. for dv, an ata/66 should be enough, so you can save some money, or get a bigger drive. however, if youre going into analog video, i would go for the ultra scsi2. be sure and get the right scsi card to match the type of drive you have, or something might blow up...

Correct me if I'm wrong, but isn't SCSI 3 the same as Ultra160? Or something like that... are they the same? If not, what is ultra 160 - i believe it is the newest, fastest SCSI...

I'd go with either Ultra2 SCSI (80 MB/sec) or Ultra160 (160 MB/sec). Both are far superior to any other drive/system out there, and will make your Mac significantly snappier.
www.macinfo.de has a good article on the different kinds of SCSI, but the site is currently down.

Just remember, no matter what Adaptec card you buy and no matter what scsi cable you buy, speed is very dependant on your hard drive's RPMs. So, if you buy a cheap 5400 ata drive or even a cheap 7200 scsi drive the throughput is only going to be so high. Not only do you have to buy the right card and cable, but you will have to buy the right hard drive. I agree with the others that if you're not going to need high quality video then a cheap hard drive will do just fine, but a $600 Ultra 160 (10,000 RPM) Cheetah will do you wonders.

Just another note:
I don't think the technology is out there yet to go above the 80MB/sec. transfer rate do to SCSI cable limitations. Everywhere I have read shows the Ultra 160 drives running 10,000 RPMs with an transfer rate of only 80MB/sec. But hey, that still f***** fast.

I have the same question - any drive will work with any card, just not as fast as you may want, right?

In theory, yes. But if I were you, I'd check with the company to make sure.

Doesn't RAID overcome that problem where you can't get over 80mb/s? I mean, wouldn't you get faster rates with 4 15000 rpm cheetas?
