Iomega must really like making hard drives aimed at Apple users, or either its MiniMax for the Mac mini and the new UltraMax 640GB drive are completely coincidental. Whatever the case, this new 640GB HDD rocks dual 320GB SATA drives in a RAID 0 or 1 array, and sports an enclosure that any Mac Pro (or PowerMac G5) owner can appreciate. It comes formatted for OS X use (HFS+), but can be reformatted for PC use, and Iomega apparently made cross-platform setup a breeze with the included "FAT32 format tools." (What, no NTFS?) What differentiates this cheese grater drive from those lookalikes is its on-the-fly ability to turn RAID on and off, as well as offering a few more nifty options not typically found on external drives. Aside from the trifecta of USB 2.0, FireWire 400, and FireWire 800 connections, you get a manual RAID switch that allows you to turn off the RAID and use the drives as JBOD (i.e. where each HDD is treated with its own drive letter). If you've been hunting for flexible external storage options, and you're a huge fan of brushed metal, the UltraMax 640GB can get paired up with your Mac (or PC) for $449.95 later this month.
