Zip track density (for the 250-Mbyte version) is 2,118 tracks per inch, with a linear bit density of 46 kbits/inch and a 29 ms access time.
Using a 2.5-inch hard disk and a rotation spin speed of 4,200 RPM in a removable cartridge increases the prospective bit density (up to 70 Gbits/inch2 using Giant Magneto Resistive, GMR, heads. But it also increases the challenges for data integrity. Like a fixed hard disk, the disk must operate in a vacuum chamber in order to ensure a precise air gap between GMR heads and the disk surface.

Perhaps the biggest benefit of an Iomega REV drive will be its virtually unlimited storage expandability. Iomega REV drives and their cost-effective 35GB/90GB (native/compressed) disks will be ideal in data-intensive settings that must maintain large archives, such as legal and financial services, medical imaging and medical records archiving, professional digital video production, video surveillance systems, and high-performance workstation applications such as graphic arts, software or gaming development.

I wonder how quick you can write to the REV drive? Does 52X CDRW still provide quicker throughput? I am guessing it does.
"Specifications Maximum Native Transfer Rate 25 MB/second
Average Native Transfer Rate 20 MB/second
Formatted Capacity 35 GB (Native) / 90 GB** (Compressed)
Average File Access Time 13 ms
Reliability 1x1015 hardware bit error rate with two-stage, enhanced error correction code
Maintenance Zero maintenance required with automatic internal head cleaning and air filtration
Shelf-Life 30-year shelf-life on Iomega REV disks "
How does this compare to the tape based storage solutions that are available on the market?
"Iomega REV drives allow you to back up and restore up to 8 times faster than tape*, access files in seconds with drag-and-drop, and secure your data with password protection. "
