Now I've seen it all

Iomega has a new cdrw drive that uses USB, that's right, the interface originally meant for low quality video at best, is going to be used for a cdrw drive.?I thought an ide cdrw drive was a bit of a stretch when compared with scsi, but looks like they've managed to get a 4X writable cd drive to work on USB.?The ZipCD external USB drive supports standard CD-Recordable (CD-R), CD-ReWriteable (CD-RW) and CD-Read-Only-Memory (CD-ROM) discs, offering customers a universal platform for organizing and archiving files without cluttering up their hard drive or network.?By supporting the USB standard, the ZipCD external USB drive is easy to attach and install to computers and laptops, eliminating the need for larger parallel port or SCSI conversion cables or rebooting the computer.?

Wow you're dumb aren't you? Hey stupid-ass, Sony has had a USB CD-R drive out for QUITE some time (CRX-100E/X is the model # I believe) and I bought it when it first came out. It's excellent. USB is amazingly feasible for a 4x CD-ROM drive. You obviously don't know what you're talking about.. killed my interest in this site, along with all the other dumbass posts here...

Well, thanks for the info, I really hadn't heard of a USB cdrw before this. I didn't mean to insult your hardware there. I was just stating that when ide burners first came out there were speed issues with writing, and usb is way slower than an ide interface. I've used usb floppy drives that were only about 1/2 the speed of a normal floppy drive, and if I recall, the floppy interface was even slower than ide. Anyway, I guess I should have looked for some actual benchmarks before commenting on it's speed.

Just some info to back me up here:
from usb.org
serial port: 115kbits/s (.115Mbits/s)
standard parallel port: 115kBYTES/s (.115MBYTES/s)
USB: 12Mbits/s (1.5MBYTES/s)
ECP/EPP parallel port: 3MBYTES/s
IDE: 3.3-16.7MBYTES/s
SCSI-1: 5MBYTES/s
SCSI-2 (Fast SCSI, Fast Narrow SCSI): 10MBYTES/s
Fast Wide SCSI (Wide SCSI): 20MBYTES/s
Ultra SCSI (SCSI-3, Fast-20, Ultra Narrow): 20MBYTES/s
UltraIDE: 33MBYTES/s
Wide Ultra SCSI (Fast Wide 20): 40MBYTES/s
Ultra2 SCSI: 40MBYTES/s
IEEE-1394: 100-400Mbits/s (12.5--50MBYTES/s)
Wide Ultra2 SCSI: 80MBYTES/s
Ultra3 SCSI: 80MBYTES/s
Wide Ultra3 SCSI: 160MBYTES/s

Now of course I'm not saying that this cdrw from either sony or iomega won't work just fine. I was more just commenting on the speed of the interface, and it's original intended use.

man fuck you

CD speed - MB/s   reply

I think 4x cd speed translates to .6MB/s
1x = 650MB/74Min ~= .15MB/s

You could almost have two of them going at the same time :)

err, you theoretically COULD have two going at the same time I mean.
