The bottom line
An external FireWire hard drive is an easy way to increase your Mac’s storage capacity. Whether the right drive for you is a portable or a desktop depends on your individual needs. But in short, you can never really have too much drive space or too many connectors.
Of the approximately 30 hard drives I’ve tested recently, three stand out as
Top Products (see the tables in this review). The Iomega Black Series Triple Interface drive is our winner in desktop hard drives, thanks to its various connection options, very quick speed (especially in copying data to the drive) and low cost per gigabyte. Our runner-up in that category, by just a hair, is Other World Computing’s Mercury Elite-AL Pro 7,200 rpm FireWire 800/400+USB2.
For a portable drive, you just can’t go wrong with the LaCie Mobile Hard Drive, Design by F.A. Porsche 7,200 rpm USB and FireWire. Its only flaw is that it doesn’t have a FireWire 800 port, but in some cases, it’s faster than drives with such a port. Other World Computing’s Mercury On-the-Go 7,200 rpm 8MB drive is the runner-up in the portable-drive category.
And as for a drive that goes perfectly with your Mac mini, you just can’t beat Newer Technology’s miniStack 7,200 rpm, with its FireWire- and USB-hub-like attributes and low cost per gigabyte.

How We Tested
—All speeds are in minutes:seconds. We ran all tests with the FireWire drives connected to a dual-2.5GHz Power Mac G5 with Mac OS X 10.3.7 installed and 512MB of RAM. All drives were tested using FireWire 800, unless it was unavailable; in those cases, we used FireWire 400. We copied a folder containing 1GB of data from our Mac’s hard drive to the external hard drive to test the drive’s read speed. We then duplicated that file on the external drive to test both read and write speeds. We also used the drive as a scratch disk when running our low-memory Adobe Photoshop CS Suite test. This test is a set of four tasks performed on a 150MB file, with Photoshop’s memory set to 50 percent.—Macworld Lab Testing by James Galbraith and Jerry Jung
