Memory Cards and Expandable Storage in Consoles
Short answer: Memory cards and external storage let you add space beyond a console's built-in storage. Support varies: some consoles use memory cards, others use external drives, and some have proprietary expansion slots. Check the listing for the storage type and size, then match it to your needs. This article explains the differences and helps you choose the right expansion for your console.
What memory cards do
Memory cards are small storage devices that plug into a console to hold games, saves, and other data. They are common on handheld consoles and some home consoles, offering a way to expand storage without opening the console. The card's capacity is measured in gigabytes (GB) or terabytes (TB), and its speed affects how quickly data is read and written.
External storage, like USB drives, serves a similar purpose for home consoles. Some consoles support external drives for storing games, while others use proprietary expansion cards. The listing will state the storage type and size, so you can compare options before buying.
When you are choosing a console, the built-in storage is only part of the picture. The ability to add more later can extend the life of the system, especially if you prefer digital downloads. For a deeper look at how much storage you might need, see our guide on how much storage you need.
- Memory cards are portable and easy to swap between devices.
- External drives can hold large libraries but may require a power source.
- Proprietary expansion cards are designed for specific consoles.
Console storage types
Different consoles use different storage methods. For example, the PlayStation 5 uses an ultra-high speed SSD for internal storage, and the Xbox Series X offers models with 1TB or 2TB SSD storage. The Nintendo Switch 2 supports microSD cards for expandable storage, while handheld gaming PCs like the Steam Deck also use microSD cards.
When reading a listing, look for the storage type: SSD, HDD, or memory card. SSDs are faster but cost more, while memory cards are convenient for handhelds. The listing will specify the storage size, such as 512GB or 1TB, and the type of expansion supported.
If you are comparing home consoles, the internal storage size often determines how many games you can keep installed. For a breakdown of consoles by storage capacity, check our best 1TB consoles and best 2TB consoles guides.
Speed and limits
Storage speed matters for loading games and transferring data. Faster storage, like SSDs, reduces wait times, while slower cards may cause longer loads. The listing may state the speed class or interface, such as UHS-I or NVMe, but if not, you can assume standard performance.
Limits vary by console. Some consoles cap the size of memory cards they support, while others have a maximum number of external drives. The official pages for each console provide details, but the listing itself is your primary source. If a limit isn't stated, check the maker's page or ask the seller.

Choosing the right expansion
Start by checking the console's built-in storage. If it's 512GB or less, you may need extra space for a large game library. For digital edition consoles, expansion is especially important since all games are downloaded. Handhelds benefit from memory cards for portability, while home consoles might use external drives.
Consider your play style: if you play a few games at a time, smaller expansion may suffice. If you download many games, look for larger cards or drives. The guides below can help you compare consoles by storage capacity.
For a list of consoles with generous built-in storage, see our best 512GB consoles guide. If you are leaning toward a digital edition, our best digital edition consoles guide highlights models that rely on expandable storage.
- For a first console, start with built-in storage and add later if needed.
- For a digital edition, plan for expansion from the start.
- For travel, a memory card is easier to carry than an external drive.
What to check before buying
Before buying a memory card or external storage, verify the console's compatibility. Check the listing for the supported type and size. Also, confirm the speed class if you plan to play games directly from the card, as slower cards may affect performance.
Read the console's official page for storage details, but rely on the listing for the specific model. If the listing doesn't mention expansion, it may not support it, so consider that in your decision.
If you are buying a handheld, the screen size and portability matter as much as storage. Our best handheld consoles guide covers models with memory card slots. For handheld gaming PCs, see best handheld gaming PCs.
Expansion options by console
Here is a quick look at how expansion works on popular console families, based on the official pages. The PlayStation 5 uses an internal SSD, and the Xbox Series X offers models with 1TB or 2TB storage. The Nintendo Switch 2 supports microSD cards, and the Steam Deck also uses microSD cards for additional storage.
These differences affect how you plan your purchases. For home consoles, you might buy a larger internal drive upfront. For handhelds, a memory card is a simple way to add space without carrying extra hardware.

| Console family | Expansion method |
|---|---|
| PlayStation 5 | Internal SSD (not memory card) |

Common questions about memory cards
Many buyers wonder whether a memory card can be used across different consoles. In most cases, cards are formatted for a specific system, so you cannot simply move one from a Nintendo Switch 2 to a Steam Deck. The listing or the console's manual will tell you the required format.
Another question is whether you can play games directly from a memory card. On many handhelds, yes, but the speed of the card matters. For the best experience, choose a card that meets the console's recommended speed class.
