Buyer's Guide: FireWire hard drives
Question 1: Which connectors?
The main connectors you’ll find on external drives are FireWire (also called FireWire 400), FireWire 800, and USB 2.0, and many drives include two or more of these interfaces. FireWire 400 is a Mac user’s best bet. It’s fast and it’s on all Macs that are less than about seven years old, and FireWire upgrades are available for many earlier systems. You can also boot your Mac from most FireWire drives in a pinch.
Apple introduced another, faster version of FireWire, FireWire 800, almost three years ago. It, too, can boot a Mac using OS X, but its speed and performance benefits are questionable. Although it’s theoretically faster than FireWire 400, FireWire 800 is far from twice as fast. In fact, a portable FireWire 400 drive with a rotational speed of 7,200 rpm may outperform a FireWire 800 drive spinning at 4,200 rpm. FireWire 800 is also not as common as FireWire 400—only Power Mac G5s and 15- and 17-inch PowerBooks ship with FireWire 800 ports.
FireWire 800 compatibility may also be an issue if you don’t have one of the Macs with a FireWire 800 port. FireWire 800 ports are compatible with FireWire 400 devices via a special FireWire 400-to-800 cable, but if you plug a FireWire 400 device into a FireWire 800 port, it will operate only at FireWire 400 speeds. If you’re a video or audio pro, FireWire 800 is nice to have, but you’ll want to make sure that the drive also has a FireWire 400 port, for maximum compatibility.
If you work across platforms, consider a drive that has a USB 2.0 port, because Windows PCs often don’t have FireWire ports. USB 2.0 is also gaining popularity on the Mac side; more and more Macs include USB 2.0 ports. USB 2.0 is backward-compatible with USB 1.1 ports (no adapter needed), which have been included on every Mac sold since the introduction of the original iMac seven years ago. But USB 1.1 can be mind-numbingly slow for anything but the smallest file transfers, and you can’t boot your Mac from a USB drive.
If you can’t decide between drives that have one or more of these interfaces, then don’t decide at all. Just buy a drive that has all three connectors—there are many to choose from. They’re called triple-interface drives, and they offer the ultimate in compatibility. Some hard drives include more than one of the same type of FireWire port. This makes it possible to connect another FireWire peripheral—a second drive, say—to the first drive instead of taking up another port on your Mac. This is often referred to as daisy chaining.
