External hard drives provide a solution to both storage and backup problems. Unlike trying to install an additional internal hard drive in your computer, most external devices are plug-and-play simple to hook up, and the number of external drives that you use is limited only by your budget. Fortunately, the price of external hard drives keeps dropping even as capacities increase, so the cost per gigabyte can be quite reasonable.
The first decision you’ll have to make is how much additional storage you need or want. External hard drives are currently available in capacities from about 80 GB to 1 terabyte or higher (you may find a single unit that contains two 1 terabyte disks). The most common sizes for external hard drives generally range from about 150 GB to 500 GB, so there are enough choices to fit different requirements and budgets.
If you’re a prolific shooter and/or capture video as well as still /images, you obviously need more storage space than if you only shot still /images from time to time. Those of you who are mathematically inclined can run some numbers to estimate how many megabytes of /images you’ll need to store and figure your capacity requirements from there.
In addition to your photographic habits, it’s important to decide whether or not you want to use one or more external hard drives to back up data. If so, how much data will you be backing up? Everything on your computer’s hard drive? Another external hard drive? The answers to these questions should also help guide you to a capacity that will meet your needs.
The type of connection used for hooking up an external hard drive to your computer will help determine how fast (or slow) the computer will be able to read and write data. Since external hard drives come with different options, take an inventory of available computer ports before you make a decision about which drive to purchase. If you have an older computer, you may need to upgrade your USB or FireWire port for optimum performance. Most external hard drives are compatible with either USB 2.0 or FireWire 400 and/or FireWire 800; some come with both USB and FireWire connections.
Keep in mind that USB devices are less expensive than FireWire and more universal since all computers have USB ports. If you don’t transfer huge amounts of data at one time, you may want to give up a little speed to save some money.
There are a number of factors besides the type of connection used that influences how quickly data is transferred or searched. For example, rpm (revolutions per minute, aka spindle speed) indicates how fast the drive is spinning. Most external hard drives have an rpm of 7200, although some drives can reach as high as 10,000. Obviously, higher rpm numbers deliver faster performance.
Since many people use external storage devices to back up data from their main hard drive, manufacturers have bundled easy-to-use backup software with their products. If you plan to use the external hard drive in this manner, it’s a good idea to concentrate on drives that offer a simple or one-touch backup solution.
Footprint And Aesthetics
If your desk is anything like mine, there’s barely room for a sheet of paper, let alone another electronic device. But hard drives come in various sizes and shapes, and some are designed to be stacked, so there’s a way to accommodate one or more drives even in the most cluttered work areas.
And if you’re concerned about looks, don’t worry. There are plenty of external drives that not only are streamlined to fit on already-crammed desks, but also sport interesting and modern designs.
To give you an idea of what’s available, we’ve compiled a selection of the different brands and types of external hard drives that are currently on the market.
