If your multimedia file collection has outgrown your internal hard drive, a large desktop drive might be just what you need. A second drive would be useful for backing up. We lab test and review the latest external hard drives to help you find the best one for you. Our buying guide explains what to look for.
Our test covers high capacity external hard drives ranging in capacity from 3 to 6 terabytes (TB). Our expert testers give every desktop hard drive a thorough workout to help find the models that:
Our interactive comparison tool helps you find out which drives come with image back-up software and which have hardware encryption. Our Recommended list will help you see quickly which models come out on top.

Connected with USB 3.0, real-time throughput are averaged over multiple runs of transferring data sets (large and small files) to and from each drive. For the Buffalo DriveStation Velocity HD-LXU3 the figures used are without using the included TurboCopy software (which averaged slightly slower figures for both read and write in our testing).

Connected with USB 3.0, real-time throughput are averaged over multiple runs of transferring data sets (large and small files) to and from each drive. For the Buffalo DriveStation Velocity HD-LXU3 this figure doesn't include results for TurboCopy software (which averaged slightly slower figures for both read and write in our testing).
Creates a full snapshot "image" of the entire drive including all software and files. Most drives will include backup software that will back up all files, but it may not create a full disk image for easy restoration of the entire drive and all contents.
Some makers provide hardware-based encryption to protect your data from prying eyes. Hardware encryption is generally considered to be superior to software-based encryption but beware that in either case an up-to-date backup is vital as a hardware failure can prevent access to all your data. Likewise, loss of the password can prevent future access.
We assess the time to get set up, how easy it is to install the software and use it to set a back-up regime, and how easy it is to restore a particular version of a backed up file. Ease of use makes up 25% of the overall score.
Performance makes up 50% of the overall score. We transfer sets of 5GB of data to and from each drive multiple times, and note both the read and write speeds to measure the drive's performance.
The number of options and potential applications available in the software. Software versatility is made up of backup (50%), security (40%) and power management (10%) support. Software versatility makes up 25% of the overall score.
