Question 2: Portable or desktop?
Now that you know what type of connectors you’re looking for, you need to think about how you’ll use your drive and how far from your desk you’ll want to carry it. FireWire cables carry data, but they can also carry power from your computer to the device—enough to power smaller hard drives (like the ones inside laptop computers) that aren’t plugged into an electrical outlet. For the purposes of this review, hard drives that are powered via FireWire are referred to as portable drives, because they tend to be smaller and lighter. And hard drives that require external power are referred to as desktop hard drives. Desktop drives are larger and heavier, but they, too, can be carried around. However, you probably won’t want to carry one far.
Because portable drives are built around physically smaller mechanisms, they’re usually more compact and easy to tote around. One downside to these drives is that they’re more expensive than desktop drives and provide less storage capacity. Currently, portable drives top out at between 100GB and 120GB, while desktop models can hold 500GB. Portable drives also tend to be slower (generally between 4,200 and 5,400 rpm) than most desktop drives (generally 7,200 rpm).
If you plan on moving your drive from system to system and place to place, then a portable drive is the way to go. If your drive will generally stay in one place and you don’t mind dealing with an additional cable and power brick, a desktop drive will be more affordable and faster. Desktop drives can even complement your workspace’s decor—for example, there are several available desktop drives that resemble a Mac mini. Because Mac minis are hard to upgrade, an external drive—especially a drive that fits the mini both physically and stylistically—can be a very attractive option. Some of these external drives for the Mac mini also act as USB 2.0 and FireWire hubs, adding to the number of available ports your system has (see “Hard Drives for Mac Mini Compared” for our ratings of these drives).
Question 3: How much storage?
Most of these FireWire hard drives come in multiple capacities. Typically, the most-expensive drives—measured in cost per gigabyte—are those with the lowest and the highest capacity in a line. Taking desktop drives as an example, many companies offer an 80GB drive as their least-expensive product. For about 25 percent more money, most companies will sell you a drive with twice the capacity, or for 50 percent more money, you can get a drive with more than three times the capacity.
For this reason, you may want to buy a larger drive than you need, even though it may seem like overkill now. As the sizes of your files and applications—as well as that of your music collection—get larger, you’ll easily fill the extra space. Be aware, though, that the highest-capacity drives cost more because they represent the latest and greatest mechanisms available on the market. As the supply of these mechanisms grows, the prices of the products based on them will come down.
Question 4: To back up or not to back up?
Everyone knows that they should back up important files and folders, but many people still don’t do it—and you know who you are. Some drives ship with backup software such as EMC Dantz’s Retrospect Express. These applications make it easy to execute a backup strategy and protect against data loss. Some desktop drives, like the Maxtor OneTouch II, go a step further by including a programmable button on the front of the drive that can initiate a backup with one press. (See Take Control of OS X Backups: Part One for more on creating backup strategies.)
