External hard drive buying guide

Choosing the best external hard drive means getting the basics right. For starters, consider capacity, interface and speed for your next portable hard drive.

External hard drive capacity

Portable HDD capacities start at one terabyte (1TB) or 2TB for external hard drives. MSY also has plenty more space, like 4TB portable hard drives and 5TB external hard drives. Alternatively, opt for stacks of storage and backup with 10TB, 12TB or up to 16TB external hard drives.

External hard drive interface

These days, USB 3.0 external hard drives are the norm, and these portable hard drives are compatible with USB 2.0 ports/devices. Alternatively, go with speedier USB-C or Thunderbolt external hard drive interfaces.

External hard drive speed

When it comes to external hard drive speeds, you’ve got two options: 5400rpm or 7200rpm. Both are affordable options, but 7200rpm drives can offer faster read and write speeds.
