How to expand console storage in 2026 without wasting money

Modern console games keep getting bigger, and internal drives fill up fast. Between 4K textures, huge day‑one patches and live service updates, even a few top titles can eat through the space on a PlayStation 5, Xbox Series X|S or Nintendo Switch.

The good news is that expanding storage is easier and safer than it used to be, as long as you know which options are worth paying for and how to avoid slow or unreliable drives.

Know what type of storage your console supports

Each current console supports storage in a different way, and getting this wrong can mean wasted performance or even a drive that does not work at all. Before buying anything, check which of your games you want to run directly from the new drive.

PlayStation 5 and Xbox Series X|S use very fast NVMe SSDs for native games, while Nintendo Switch uses microSD cards. External USB drives still have a place, but mostly for older titles or backups, not for the newest big budget releases.

PlayStation 5: internal SSD vs external USB

The PS5 has an internal M.2 slot that lets you add a PCIe 4.0 NVMe SSD. To get performance close to the built‑in drive, look for a model that advertises at least 5,500 MB/s sequential read speed and includes a heatsink or supports adding one. Sony lists broad requirements on its support site and many major brands clearly mark compatibility.

Installing the drive is straightforward: power off completely, remove the side panel, open the M.2 bay, insert the SSD at an angle, screw it down, close the cover and panel, then format it when the console prompts you. After that, you can set the PS5 to install new PS5 games on the new drive by default.

External USB drives still matter for PS4 titles and for archiving PS5 games. A decent USB 3.0 HDD or SSD can hold a large library of PS4 games that run directly from the drive. PS5 titles can be moved to USB for storage, then copied back to internal or M.2 SSD when you want to play, which is much faster than redownloading.

Xbox Series X|S: expansion cards and USB drives

Xbox Series X|S uses proprietary expansion cards for full speed storage. These plug into the expansion slot on the back and act like internal storage for Series X|S games. Current cards are available from a few brands in sizes like 512 GB, 1 TB and 2 TB, and they install in seconds.

For Xbox One, Xbox 360 and original Xbox games, and for archiving Series X|S titles, a standard USB 3.0 drive is fine. As with PS5, you can keep newer games parked on an external drive, then move them back onto the internal SSD or expansion card when you plan to play them.

If you often switch between a handful of live service games, an expansion card is worth prioritising. If you mostly rotate through one big game at a time, a cheaper USB drive used as a cold storage library can be more cost effective.

Nintendo Switch: getting the most from a microSD card

For the Switch, a good quality microSD card is usually the only extra storage you need. Capacity matters more than extreme speed, but there are still a few key specs. Look for at least a UHS‑I U3, V30 card from a recognised brand, as these offer solid performance for downloads and load times without a huge price premium.

Before installing a microSD card, power off the Switch completely, insert the card in the rear slot (or under the stand on some models), then reboot. The console will format it. Once set up, you can move software data to the microSD card from the system settings and install future downloads there by default.

Since Switch games often receive updates, avoid extremely cheap or unbranded cards. They are more likely to fail, which can corrupt downloads and cost you time. A reliable 256 GB or 512 GB card is a good balance for most players.

Picking between HDDs and SSDs for external storage

For external drives on PS5, Xbox or even a gaming PC, the main trade‑off is price versus speed. Mechanical HDDs give more terabytes per dollar, which is ideal for large libraries of older or less demanding games, but they have longer load times and are more prone to damage from drops.

External SATA or NVMe SSDs are more expensive per gigabyte but much faster at loading and copying games. They also have no moving parts, which makes them better for travel and daily plugging in and out. For a mixed library, many players use a smaller SSD for favourites and an HDD for everything else.

Practical tips to avoid headaches

Regardless of console, a few habits can keep expanded storage reliable. Periodically check available space and uninstall games you know you will not return to soon, especially huge titles with massive updates. This keeps drives from filling completely, which can slow performance and complicate future updates.

Use the platform’s built‑in options to move and manage games, rather than deleting files at the drive level from a PC. Always safely power down or eject drives before unplugging them. If you play on multiple consoles, label each drive physically so you do not plug the wrong one in after a move or trip.

Planning for the next few years

Storage prices tend to fall over time, but game sizes keep growing. A good strategy is to add enough space to be comfortable for the next two or three years, not to cover every game you might ever want installed. For most players, that means 1 or 2 TB on PS5 or Xbox and at least 256 GB extra on Switch.

If you treat external drives gently, avoid unbranded storage and keep your libraries organised, you can expand your console’s capacity in a way that feels invisible in daily play, while saving money for the games themselves instead of overbuying hardware.
