Created 11/20/98 by Rob Art Morgan,

- The USB Zip drive is twice as fast
as the USB iMation SuperDisk.
- The USB Zip drive is only 10% slower
than a SCSI Zip drive.
- Neither the USB Zip or iMation
SuperDrive comes close to the speed of the internal iMac 4 Gig
- In defense of the iMation SuperDisk,

disks and matches the iMac color scheme more closely.
- I wonder why Iomega didn't just add

- I wonder why Apple didn't make the
CD-ROM hot swappable with a Zip or floppy a la PowerBook.
- Before you sell your SCSI Zip drive,
you might check into the
new USB to SCSI adapter by MicroTech.
Equipment & Procedures
- The USB Zip and iMation SuperDrive
were tested on a Version A iMac with 32MB of RAM.
- The external SCSI Zip was run on a
7500 with a 300MHz G3 cpu board.
- Both computers ran Mac OS 8.5 with
minimal extensions, Virtual Memory ON, File Sharing OFF, Open
Transport OFF, NO MathLibMoto, NO Speed Doubler, NO Ram Doubler,
512K Disk Cache setting
- The MacBench
5.0 general disk test was
used. MacBench is the product of Ziff-Davis. The CD-ROM costs $5
Thanks go to Iomega
for getting me an early model of USB Zip to test. They appeared in
the local CompUSA as of today (11/20/98).
