Introduction

Bringing high-speed CD-RW drives out of the casing seems to be the norm these days. Not too long ago we gave our take on the latest Iomega Predator, a portable CD-RW based on the 40x12x40x terminology. Today we shall take a look at another Iomega drive, the Iomega External USB 2.0 48x24x48x CD-RW - somewhat similar to the Iomega Panther we saw at the end of last year.

The External 48x24x48x CD-RW isn't in the same league as the Iomega Predator series nor other ultra-slim CD-RWs, where form factor is taken into consideration to make the drive as easily portable as possible. In the case of the External 48x24x48x, the drive is a little on the huge side - which is understandably so, because it really is just an internal drive retrofitted into an external casing with a USB 2.0 interface.
