With its 1TB capacity, Iomega's UltraMax provides enough space to alleviate your storage woes. But it is really only for Mac users.

While it may seem like your hard drive will always have room for all your media, at some point it's going to hit its limits. So the prudent approach is to purchase a new drive before you reach that point.

With its 1TB capacity, Iomega's UltraMax provides enough space to alleviate your storage woes. And, at around £230, it's reasonably priced - although there are less expensive options, such as the SimpleTech USB 2.0http://www.pcadvisor.co.uk/reviews/index.cfm?reviewid=1663.

Depending on its storage size and connectivity options, the Iomega UltraMax either features a slender silver anodized aluminium case with a silver plastic stand that helps it stand vertically, or a more boxy aluminium body with two horizontal drives. There are versions of the Iomega UltraMax that use USB 2.0 and FireWire connectivity. Others have eSata and USB.

A blue LED activity light sits behind the ventilation perforations on the front panel while a security port allows you to tether the unit to your work table as necessary. Besides the 1TB capacity unit we reviewed, the drive also comes in a 500GB version, 640GB, 750GB, as well as a 1.5TB model that uses two drives and a larger enclosure.

The UltraMax hard drives are designed to be compatible with Macs, and work out of the box with OS X 10.1 or above on Apple computers with an Intel processor or G3 processor or higher and a built-in USB or FireWire connection.

You can, however, reformat the UltraMax Drive to NTFS or FAT32 for use with a PC (instructions included). So it's compatible with Windows 2000, XP and Vista. FAT32 format allows cross-platform use.

To operate the UltraMax, simply plug in the external power supply and cable the drive to your Mac using one of the four available types of ports - FireWire 400, FireWire 800, USB, or eSATA. The UltraMax comes with dual FireWire 800 ports to allow you to connect multiple devices.

We found the connector spacing on the Iomega UltraMax's back panel to be slightly roomier than some others we've tested.
