Iomega has doubled the capacity of its 35GB Rev removable hard drive which challenges the tape back-up market by offering faster file restoring.

The I/O rate of the 70GB Rev - the reinvented version of Iomega's once ubiquitous Zip and Jaz drives - has gone up too, from 25 to 30Mbit/s.

Using a tape system will probably still work out cheaper over time than Iomega's system, but disk is much faster, especially at restoring files.

And the reason why no one else has a disk-based autoloader is because only Iomega has disks that are flat and thin enough to fit inside an auto loader's casing.

Iomega has been struggling to find Zip/Jaz replacement products and the Rev seems to be the chosen one, now in its second generation.

The company also has new senior management and no longer looks like a company up for sale. However, to some it no longer looks like a storage company for the long-haul either.

Recently it bought a managed services company called CSCI, which gives it hundreds of customers using OfficeScreen, CSCI's managed virtual private network (VPNs) that securely link offices and remote workers in small and medium businesses.

The purchase marked a move away from Iomega as a storage company, with its CEO Jonathan Huberman saying at the time: "With the addition of OfficeScreen, Iomega is taking the first step toward becoming a managed services company."

Of course Iomega can sell Rev to its newly acquired CSCI customers but the likelihood may be that Iomega primarily focuses on building the CSCI customer base instead.

It quotes independent market analysis that the global market for managed security services is expected to be $2.9 billion in 2006, growing to $3.7 billion in 2008.
