Factors to Consider When Buying an External Hard Drive
An external hard drive is a storage device physically separate from a computer. It usually connects over USB and may have its own added power source. They are generally larger and have more capacity than a USB flash drive, though the most expensive USB flash drives rival the storage of some external hard drives.

It's less expensive to buy a single external hard disk drive in the capacity you need than it is to buy multiple, smaller drives. External solid state drives are different. Price rises quickly with capacity: 16TB drives are often $3,000.

This makes them more fragile, slower, and louder when in use. There's also a limit to how small they can become, as the smallest hard disks in use are 2.5 inches across. These problems are offset by low pricing: hard disks have the highest storage capacity for your money.

This makes them more reliable, as the drive lacks spinning components that can break. They're silent and often smaller than external drives with a hard disk. The solid-state chips they use are more expensive, however, so expect to pay more per gigabyte.

How Much Storage Capacity Should an External Hard Drive Have
The simple answer, of course, is "as much as you need." Yet this can might be difficult to determine if the files you want to store are strung across multiple folders on your PC. Prices fluctuate constantly in this market, but we suggest starting at a 1 terabyte (1TB) model as they offer quite a bit of room and are usually only a couple of dollars more than a smaller capacity drive.

A larger drive might be necessary if you want to store dozens of hours of 4K video, thousands of DSLR photos, super-sized images, or vector-based arts. If you are working with those kinds of files, you likely know how big the files are and how many you need to store.

If this is true of your computer, consider sticking to a slower and less expensive external hard drive, since you won't see the benefit of newer, faster models. USB Type-C is the newest connection and offers quick data speeds as well as power all over one cable. USB Type-C is physically different from the older USB-A connection.

You can buy a USB-C to USB-A adapter if your computer lacks USB-C, but the USB Type-A port might not be able to provide power to the drive (if the drive doesn't come with its own power supply). There's one last connection to mention: Thunderbolt. Thunderbolt 3 and Thunderbolt 4 are physically compatible with USB-C but often quicker, with a mandatory bandwidth of 40 gigabytes per second.

Thunderbolt isn't used by most external drives because USB is usually fast enough, but you may encounter Thunderbolt on high-end external drives. You'll need a Thunderbolt 3 port on your PC to make the most of this connection.

This is also true of older external drives produced before USB 3 and Thunderbolt were common. An external hard drive that requires its own power isn't really meant to be moved around a lot even if it is, technically, able to be moved about.
