Modern games are huge, and a single big release can take 100GB or more, so storage is one of the specs that matters most on a console. This guide covers how much storage the PS5, Xbox Series X and S, Nintendo Switch, and Switch 2 really have, what it costs to expand each one in 2026, and what to check when you buy or sell used.

Updated October 10, 2026, with a full Nintendo Switch 2 section, 2026 storage expansion prices, and current Swappa prices.
Quick Answer
No console gives you the full number on the box. A PS5 has 825GB with about 667GB usable, an Xbox Series X has 1TB with about 802GB usable, a Series S has 512GB with about 364GB usable, and a Switch 2 has 256GB with about 249GB free. The PS5 takes a standard M.2 SSD, Xbox uses a proprietary expansion card, the original Switch takes ordinary microSD, and the Switch 2 accepts only microSD Express. Adding storage got much more expensive in 2026, but on Swappa the bigger-storage version of a console often sells for only a little more than the base model, so it’s usually the better used buy.

Why Storage Is the Spec That Bites You
The storage number on the box is not what you get to use. The operating system and reserved system files take a cut before you install a single game, which routinely surprises buyers who expect a “1TB” console to hold a terabyte of games.
Game sizes make it worse. Many current games have to be installed on the console’s fast internal drive (or approved expansion) to run, and big titles can top 100GB with updates. Physical games don’t get you out of it either: discs and cartridges still install data, and Nintendo Switch 2 Game-Key Cards hold little or no game data, so the game downloads to your storage.
Two 2026 changes raise the stakes. Memory and storage prices climbed sharply this year as AI data centers bought up chip supply (Microsoft said its console memory and storage costs rose more than 2.5x), so adding space costs far more than it did in 2025. And Sony will stop producing discs for new PlayStation games starting in January 2028, which means more downloads in the years ahead.

How Much Storage Each Console Actually Has
Internal capacity and usable capacity are two different numbers. Here’s how the current and recent lineup compares.
| Console | Internal Storage | Roughly Usable | How It Expands |
|---|---|---|---|
| PS5 and PS5 Digital (2020) | 825GB | ~667GB | M.2 NVMe SSD, USB |
| PS5 Slim | 1TB | ~848GB | M.2 NVMe SSD, USB |
| PS5 Slim Digital | 1TB (some later units 825GB) | ~848GB (~667GB on 825GB units) | M.2 NVMe SSD, USB |
| PS5 Pro | 2TB | ~1.89TB | M.2 NVMe SSD, USB |
| Xbox Series X (disc or Digital) | 1TB | ~802GB | Expansion card, USB for storage |
| Xbox Series S (512GB) | 512GB | ~364GB | Expansion card, USB for storage |
| Xbox Series S (1TB) | 1TB | ~800GB | Expansion card, USB for storage |
| Nintendo Switch 2 | 256GB | ~249GB | microSD Express only |
| Nintendo Switch OLED | 64GB | ~58GB | microSD |
| Nintendo Switch | 32GB | ~26GB | microSD |
| Nintendo Switch Lite | 32GB | ~26GB | microSD |
| PS4 and PS4 Slim | 500GB or 1TB | Varies | Swappable 2.5″ drive, USB |
| PS4 Pro | 1TB | Varies | Swappable 2.5″ drive, USB |
| Xbox One and Xbox One S | 500GB to 2TB | Varies | USB |
Usable figures are approximate. They reflect what each console reports after system files and shrink slightly as system updates grow.
The takeaway: budget for less than the box says, and factor expansion into the price of any console you’re seriously considering.
Bigger Storage Costs Less on the Used Market
New, stepping up to more storage is expensive. Used, buyers barely pay for it. Here’s what Swappa’s sales data showed on October 10, 2026.
| Model | Storage Options | Price Gap New | Avg. Used Sale on Swappa | Used Price Gap |
|---|---|---|---|---|
| Xbox Series S | 512GB vs. 1TB | $100 ($499.99 vs. $599.99) | $313 vs. $334 | About $21 |
| Steam Deck OLED | 512GB vs. 1TB | $160 ($789 vs. $949) | $614 vs. $716 | About $102 |
| PS5 Slim Digital | 825GB vs. 1TB | Not sold side by side | $466 vs. $507 | About $41 |
| Steam Deck (LCD) | 64GB vs. 512GB | Discontinued | $392 vs. $448 | About $56 |
| PS4 Slim | 500GB vs. 1TB | Discontinued | $134 vs. $142 | About $8 |
New prices are US list prices as of October 10, 2026. Used prices are Swappa average sale prices on the same date, rounded. Some configurations have only a handful of sales, and prices move with condition and what’s in the box, so check the live price pages before you buy.
For buyers, that makes the higher-capacity model the smart used pick: a 1TB Series S for about $21 more spares you a roughly $200 expansion card later. For sellers, it means extra storage helps a listing stand out but rarely adds its full retail value, so price against recent sales for your exact configuration.
PlayStation Storage: PS5 and PS4
PS5 expansion is the most open of the major consoles. Every PS5 model, including the original, the Slim, and the PS5 Pro, has an internal M.2 slot that takes a standard NVMe SSD. Sony’s requirements:
- PCIe Gen4 x4 M.2 NVMe SSD (M.2 SATA drives don’t work)
- 250GB to 8TB capacity
- Sequential read speed of 5,500MB/s or faster recommended
- Size 2230, 2242, 2260, 2280, or 22110
- A heatsink or other cooling is required, and the drive with its cooling must be no wider than 25mm and no thicker than 11.25mm
Update the console to the latest system software before you install a drive (Sony support).
The open slot no longer guarantees savings. Because the PS5 uses off-the-shelf drives, its storage costs follow the regular SSD market, and SSD prices more than doubled between mid-2025 and mid-2026. On October 10, 2026, Samsung listed its 990 PRO with Heatsink at $339.99 for 1TB and $669.99 for 2TB, and SanDisk had its Optimus GX PRO 850X with heatsink on sale for $289.99 (1TB) and $549.99 (2TB). Budget Gen4 drives cost less, though you may need to add a heatsink. That makes a used PS5 with an SSD already installed worth more than it used to be. Confirm the drive shows up under Settings > Storage before you buy.
USB drives are for storage, not PS5 play. A PS5 can use a USB drive (SuperSpeed USB 5Gbps or faster, 250GB to 8TB) as extended storage. You can play PS4 games straight from it, but PS5 games have to be copied back to the internal SSD or M.2 drive to play (Sony support).
Watch the storage on PS5 Slim Digital listings. Most have 1TB, but some later units (the CFI-2100 series) shipped with 825GB. Swappa sells both: in October 2026, the 825GB version sold for about $466 and the 1TB version for about $507.
PS4 storage works the old-fashioned way. The PS4, PS4 Slim, and PS4 Pro use a standard 2.5-inch SATA drive you can swap, and they support USB extended storage too. A used PS4 may already have a bigger drive inside, so check Settings > Storage rather than trusting the factory capacity. Used PS4 and PS4 Slim consoles sold for about $123 to $142 on Swappa in October 2026.
For model-by-model guidance, see the Used PlayStation Buyer’s Guide: PS5 vs. PS5 Pro vs. PS4. To shop by model, browse the PS5 Slim, PS5 Pro, original PS5, PS4 Slim 1TB, and PS4 Pro.

Xbox Storage: Series X, Series S, and One
Xbox uses a proprietary card. The Xbox Series X and Series S expand through a Storage Expansion Card that plugs into a slot on the back. It matches the internal SSD’s speed, so you can play Series X and S games directly from it, but it works only on Series X and S consoles, not Xbox One or PC. Seagate and SanDisk make the licensed cards. Here’s what they cost on October 10, 2026:
| Card | Capacities | Price |
|---|---|---|
| Seagate Storage Expansion Card | 1TB, 2TB, 4TB | $199.99 (1TB) and $359.99 (2TB) MSRP; 4TB price not listed |
| SanDisk Optimus GX C50 (formerly WD_Black C50) | 512GB, 1TB, 2TB | $119.99, $239.99, and $479.99 on sale at SanDisk (list $149.99, $299.99, and $599.99) |
That’s no longer a big premium over PlayStation storage. After this year’s SSD price jump, a 1TB Xbox card costs about the same as, or less than, a premium 1TB PS5 drive with a heatsink. Prices move often, so check current retail before you budget.
The Series S is where storage stings most. The 512GB model leaves about 364GB for games, and because it’s digital-only, every game has to download. The 1TB Series S eases this a lot, and used it barely costs more: about $334 on Swappa against $313 for the 512GB model in October 2026. Supply of the 1TB model is thin, so check the Series S 1TB listings often, or browse the Series S 512GB.
The Series X has 1TB (about 802GB usable). Microsoft discontinued the 2TB Series X with its August 2026 price changes, so once retail stock runs out, used is the only way to get that capacity built in. A used Xbox Series X sold for about $544 on Swappa in October 2026, against $799.99 new.
USB drives store Series X and S games but can’t run them. Any Xbox accepts a USB 3.0 or faster external drive of at least 128GB. On a Series X or S, it can run Xbox One, Xbox 360, and original Xbox games, but games optimized for Series X and S must be moved to the internal SSD or an expansion card before you can play them. A USB drive still works as a cheap “game vault” so you don’t have to re-download. On an Xbox One or Xbox One S, a USB drive can both store and play games.
For the full breakdown, read the Used Xbox Buyer’s Guide: Series X vs. Series S vs. One.

Nintendo Switch 2 Storage: 256GB and microSD Express
The Switch 2 starts with far more room than the original Switch. It has 256GB of internal storage, eight times the original Switch, and early reports put the free space at about 249GB out of the box. That still fills up if you buy digitally or use Game-Key Cards, which download the game to the console.
Expansion requires microSD Express. Nintendo says the Switch 2 is only compatible with microSD Express cards, up to 2TB, and the console needs an internet system update the first time you use one. A card can hold downloaded games, updates, DLC, screenshots, and videos. Save data is different: it stays in the console’s system memory, not on the card (Nintendo support).
Your old Switch cards won’t work for games. A standard microSD card from an original Switch can’t store or run Switch 2 games. The only thing a Switch 2 can do with one is import screenshots and videos you captured on an original Switch. If you’re upgrading, budget for an Express card.
Express cards cost more. On October 10, 2026, SanDisk’s licensed microSD Express card for Switch 2 was on sale for $64.99 (256GB), $159.99 (512GB), and $399.99 (1TB, out of stock), against list prices of $81.99, $249.99, and $499.99. If a used Switch 2 comes with a card, make sure it’s labeled microSD Express, and count it as real value.
Used Switch 2 supply has grown. Swappa had 16 Switch 2 listings on October 10, 2026, most priced between about $420 and $520, with bundles that add games or controllers running higher. New, the Switch 2 has cost $499.99 since September 1, 2026. Swappa doesn’t have enough completed sales yet for an average sale price, so compare listings against the new price and add up what a bundle includes.
Before you buy, confirm the console isn’t banned from online play, since a ban stays with the hardware after a reset. The Used Nintendo Switch 2 Buyer’s Guide walks through that check and the rest of the inspection.

Original Nintendo Switch Storage: microSD
The original Switch and Switch Lite ship with just 32GB (about 26GB free), and the Switch OLED doubles that to 64GB (about 58GB free). That’s why a microSD card is close to mandatory. The original Switch family takes standard microSD cards (microSDHC or microSDXC) up to 2TB, which cost less than microSD Express cards of the same size. microSD Express cards also work in an original Switch, but only at standard microSD speed.
A used Switch that comes with a large card saves you a purchase, and the consoles themselves are cheap now that buyers are moving to the Switch 2. A used Switch OLED sold for about $203 on Swappa in October 2026 (against $399.99 new), and an original Switch for about $141 (against $339.99).

A Quick Note on Handhelds
Handheld gaming PCs handle storage more like laptops than consoles. Most have a user-replaceable M.2 SSD (the Steam Deck uses the small 2230 size) plus a microSD slot, so running out of space is easier to fix.
The Steam Deck OLED comes in 512GB and 1TB ($789 and $949 new since May 2026), and used units sold for about $614 and $716 on Swappa in October 2026. The discontinued Steam Deck LCD came in 64GB, 256GB, and 512GB. The 64GB model uses slower eMMC storage, so the 256GB or 512GB is the better used pick for not much more. Other options include the ROG Xbox Ally X and Lenovo Legion Go S.
For the full rundown, see Used Handheld Gaming PCs: Steam Deck vs. ROG Ally vs. Legion Go.
Disc vs. Digital: Why It Hits Your Storage
With a disc console, games still install to the drive, but you can delete a game and reinstall it from the disc instead of re-downloading it. With a digital-only console, every game is a download, so you lean on storage much harder. Digital-only models include the PS5 Digital Edition, PS5 Slim Digital, PS5 Pro (unless you add Sony’s disc drive), Xbox Series S, and Xbox Series X Digital. Every Nintendo Switch and Switch 2, including the Switch Lite, plays cartridges, though Switch 2 Game-Key Cards still download the game.
Sony’s plan to stop producing discs for new PlayStation games in January 2028 tilts things further toward downloads. Existing disc games keep working, but new releases after that will be digital, so plan on needing more storage over a console’s life. If you’re buying a digital-only console used, treat storage as a higher priority and expect to expand sooner.
What to Check on Storage When Buying Used
Storage is one of the easiest specs for a listing to get wrong, intentionally or not. Before you buy:
- Confirm the capacity in settings, not just the model name: Settings > Storage on PS5 and PS4, Settings > System > Storage devices on Xbox, and System Settings > Data Management on Switch and Switch 2. This matters most on PS4 (swappable drives) and PS5 Slim Digital (825GB and 1TB versions).
- Ask what expansion is included. An installed PS5 M.2 SSD, an Xbox expansion card, or a microSD card has real value at 2026 prices, so it should be spelled out in the listing.
- Check that added storage is recognized. A PS5’s M.2 drive should appear in the Storage menu, an Xbox card under Storage devices, and a Switch card under Data Management.
- On Switch 2, confirm any card is microSD Express. A standard card won’t hold games.
- Test for errors. Storage should read at full capacity, and a game should launch from expanded storage without warnings.
For the complete pre-purchase walkthrough, follow How to Inspect a Used Console Before You Buy.
Storage and Resale: Selling Tips
Storage shapes how your listing reads, but as the Swappa data above shows, buyers pay less for extra capacity than retail prices suggest. Price against recent sales for your exact model and storage on the Swappa price pages, and put the capacity in the listing details.
If you’re including extra storage, say exactly what it is: the brand and size of the M.2 SSD, expansion card, or microSD card. At 2026 storage prices, an included drive or card is a real selling point, especially a microSD Express card with a Switch 2.
Before you list:
- Back up your saves. Switch and Switch 2 saves live in system memory, not on the card, so back them up first. See How to back up your Nintendo Switch game saves before selling it on Swappa.
- Clear any included storage. Delete your games and data from an included M.2 SSD, Xbox card, or USB drive. On a Switch or Switch 2, format any card you’re including from System Settings > System > Formatting Options, since downloaded software on it is tied to your console and won’t run for the buyer anyway.
- Unlink your accounts and factory reset. Disable Console Sharing and Offline Play on a PS5, remove the console as your home Xbox, or unlink a Switch from your Virtual Game Cards, then reset. How to Sell a Used Console and Games for the Most Money covers each step, and How to factory reset a Nintendo Switch has the Nintendo details.
Swappa’s listing standards require consoles to be fully functional, so a console with a failing drive or a dead card slot doesn’t qualify.

FAQ
Why does my console show less storage than advertised?
The operating system and reserved system files take part of the drive before you install anything. A PS5 leaves about 667GB usable from its 825GB drive, an Xbox Series X about 802GB from 1TB, a Series S about 364GB from 512GB, and a Switch 2 about 249GB from 256GB. The advertised number is the raw drive size, not the space available for games.
Can I expand PS5 storage, and what SSD do I need?
Yes. Every PS5 model, including the Slim and PS5 Pro, has an internal M.2 slot for a PCIe Gen4 x4 NVMe SSD from 250GB to 8TB, with read speeds of 5,500MB/s or faster recommended and cooling that keeps the drive within 25mm wide and 11.25mm thick. You can also store PS5 games on a USB drive, but you have to move them back to play.
How much does Xbox storage expansion cost in 2026?
On October 10, 2026, Seagate’s Storage Expansion Card listed at $199.99 for 1TB and $359.99 for 2TB, and SanDisk’s Optimus GX C50 was on sale for $239.99 (1TB) and $479.99 (2TB). Because SSD prices rose sharply in 2026, that’s now close to, or below, the price of a premium PS5 SSD with a heatsink at the same capacity.
Do my old Switch microSD cards work in the Switch 2?
No, not for games. The Switch 2 only accepts microSD Express cards for game storage, up to 2TB. A standard microSD card from an original Switch can only be used to import screenshots and videos captured on that Switch, so budget for an Express card if one isn’t included.
Does extra storage make a used console worth more?
A little, but less than retail prices suggest. On Swappa in October 2026, a 1TB Xbox Series S sold for about $21 more than the 512GB model, even though it costs $100 more new. That makes the bigger-storage model a good used buy, and it means sellers should price against recent sales for their exact configuration.
How do I check real storage capacity on a used console?
Open the storage menu: Settings > Storage on PS5 and PS4, Settings > System > Storage devices on Xbox, or System Settings > Data Management on Switch and Switch 2. Confirm the total capacity and free space, and check that any included SSD, expansion card, or microSD card shows up.
The Bottom Line
Storage is the spec most people underestimate. Assume usable space is lower than the box claims, know how each platform expands (an open M.2 slot on PS5, proprietary cards on Xbox, microSD on the original Switch, and microSD Express on Switch 2), and expect adding storage to cost more in 2026 than it did a year ago. On the used market, the bigger-storage version of a console often costs only a little more, so it’s usually worth buying up.
Swappa lists used consoles across every major platform with storage spelled out, backed by buyer protection through PayPal.
