With ballooning game install sizes, storage space is at a premium this console generation. The 500GB or 1TB hard drive that comes as standard in the various PlayStation 4 models may seem like plenty at first, but it fills up quickly. Even upgrading that hard drive is only a temporary fix - the console only supports drives up to 2TB, a limit plenty of players are likely to hit long before the PS5 comes out.
There's good news though. PS4 software upgrade 4.5 brought with it support for external hard drives, opening up the potential for limitless storage - you need never uninstall a game or delete a screenshot again.
The PS4 now supports USB 3.0 hard drives up to 8TB, and if you somehow manage to fill that up you can always just buy another (the PS4 won't support both at once, but you can always swap between them).
It's worth bearing in mind that any hard drive you use to install games has to be formatted for the PS4, meaning you won't be able to use it to store any other files or backups - that's why you might want to buy a new drive for the purpose, rather than re-use an existing one, unless you know you don't need it for anything else.
To find out how to format an external hard drive for the PS4, check out our guide to managing your storage on the console. And if you're looking to upgrade the internal hard drive, we have a guide for that too.
A quick word on the list below. All of the drives were testing multiple times on our PC test rig (not on a PS4), but all will be compatible with the console. We've also only included drives available in at least 500GB, because anything smaller would fill up too quickly to be of much use.

If you’re after a large capacity portable drive for backing up your photos, videos, music and other precious data, the Samsung T3 is a great choice. However, a traditional hard drive is still much, much cheaper if speed isn’t your main priority.

At less than £85 the Transcend StoreJet 25M3 is very good value for money, costing just 4.15p per gigabyte for a decently resilient portable drive. It's well made and should serve splendidly as a highly capacious data store.

Like Tesco Basics, the Toshiba Canvio Basics lives up to its name, a basic portable drive with no frills in its packaging, style or feature set. However there’s also little sign of any compromise in its overall performance and usability, excepting a slower than usual small-file random write issue. Importantly for many potential buyers, it’s one of the cheapest drives available at fewer than 4 pennies per gigabyte, without compromising the build quality required of its role.
