PS4 External Hard Drive Compatibility Guide

Adding a compatible external hard drive to PS4
After more than two years now since Sony released its wide-range support for USB storage devices featured by PS4 System Update 4.5, PS4 users are allowed to use an external hard drive, not for backup & Restore this time, but for expanding the main system storage that will enable them to install their games and apps directly to the external HDD and launching them from there, which was not available since the first support of USB storage devices that came with version 2.5 of PS4 System Software Update almost 3 years ago.

This extensive support for external hard drives has impressed the overwhelming majority of users (if not all), as it offers a much easier way to expand PS4 storage without the need to go through the hassles of replacing and upgrading the stock internal hard drive of PS4, which also requires a fresh new installation of PS4 Software from scratch, and re-installing/recovering all your games and apps on the new hard drive, which is not comfortable for many savvies, taking in consideration also that it needs at least 1 and half hours for completion.

But, before trying to use an external hard drive on PS4, you need to find a fully-compatible one that PS4 system accepts, otherwise you won’t be able to enjoy the features PS4 system supports in USB storage devices.

What’s PS4 External HDD Compatibility?

PS4 External hard drive compatibility is a set of specifications that an external hard drive must have in order to be deemed as PS4 Compatible, and accordingly be used a fully functioning extended storage device alongside with the main system storage device. There are also what we can call Compatibility Standards, which are a set of rules the external hard drive must abide by in order to work properly and flawlessly on PS4.

These specifications and standards vary depending on how you want to use an external HDD on PS4. Is it for Backup & Restore purpose? Or is it as a storage extension? Unfortunately you cannot use ONE external HDD for both purposes, you must sacrifice one for the other.

Backup Storage Compatibility

External storage devices connect to PS4 via the USB ports located on the rear side of PS4If you want to use your external hard drive on PS4 for backup and restore purpose, ensure that it meets the following specifications:

  • It’s configured with USB connection (No matter what generation it is).
  • Not larger than 8tb of storage capacity. Theoretically it can be any size less.
  • Singly-layer drives are supported only. Dual-layers may work, but only one layer will be working then.

That’s all for the specifications part. As for the standards, they are:

  • Must be formatted using either FAT32 or exFAT file system.
  • Shouldn’t be divided into multiple partitions. PS4 system only accept a single-partitioned drive
  • PS4 System Software update 2.5 and above must be installed.

Once your hard drive meets all these specifications and strictly conform to the above standards, then it should be fully qualified for the purpose it’s picked for.

Extended Storage Compatibility

The case with extended storage solution is a bit more complicated, as the support for this feature is more limited.

You have to ensure that your external hard drive meets the following specifications:

  • Supports USB 3.0 Connection. Older generations are obsolete and not supported.
  • Storage capacity must range from 250gb minimum to 8tb maximum. Any storage outside this range is not supported.
  • Singly-layer drives are supported only. Dual-layers may work, but only one layer will be working then.

As for the standards that the external HDD must conform to are:

  • Must connect directly to USB port, not via a USB hub or any other connection medium.
  • Cable connection is only accepted. Wireless connection is rejected.
  • Must be formatted and encrypted using PS4 format utility. This is done automatically once PS4 recognizes and approves the connected drive.

Now, if you see that your external hard drive fits into this purpose, then you can directly connect it to PS4 and follow the easy steps that will appear on the screen once PS4 system recognizes your drive.

Note that you may want to restart PS4 system while your external HDD is connected to it in order to get it recognized by the system, as sometimes this is required.

Compatibility with PS4 Pro and PS4 Slim

The specifications and standards stated above are for all models of PS4, whether it’s the standard model, Slim or Pro. There’s no additional requirement to get an external hard drive working on any of these three models.

Maybe it’s good to say that if you’re using PS4 Pro model, then look forward to buying a large and fast external hard drive, as with the constant support Sony release for PS4 Pro, it is easy to predict that games designed for PS4 will be larger in size than others in order to support the premium features of PS4 Pro, such as 4k viewing mode. So, don’t look just for a compatible external hard drive with PS4 Pro, but also pick a solid drive for this purpose.

USB Flash Drive Compatibility

It’s worth to mention here that all USB sticks are subjected to the same rules of external hard drives. But usually, a USB flash drive (stick) is used for lightweight storage, such as storing game saves or small movie clips. Yes, it can be used as a full external storage solution the same as an external hard drive is used, but this will be costly for you, as you have to buy a large USB stick that costs you double or triple the price of an ordinary external hard drive of the same size.
