The best SSD for Steam Deck OLED lets you go past the 512GB or 1TB the OLED ships with. Valve's Steam Deck OLED tech specs list 512GB and 1TB NVMe models, a 7.4 inch HDR OLED screen and a 50Whr battery. The iFixit Steam Deck OLED SSD replacement guide confirms the OLED uses a single-sided M.2 2230 SSD.
We picked five M.2 2230 drives whose Amazon listings name the Steam Deck, with an eye on the OLED owner who wants 2TB. We checked every listing on Amazon in October 2026 and used the specs the makers publish there. We do not list prices because Amazon prices change in real time; use the buttons to see the current price and availability. Scores are our editorial scores out of 10, not Amazon customer ratings.

In-Depth Reviews
1. What Is Different About the OLED Swap?
The iFixit Steam Deck OLED SSD replacement guide uses a T6 Torx driver for the eight 5.8mm back cover screws and the 3.3mm SSD screw. iFixit rates the job Moderate, with 30 minutes to an hour needed.
iFixit also suggests letting the battery fall below 25% and enabling battery storage mode in the BIOS before you open it, and warns you to remove any microSD card first. Keep the ESD shielding on the old drive intact, because it moves to the new SSD.
2. Which Capacity Makes Sense for an OLED?
If you own the 512GB OLED, a 1TB drive doubles your space. If you already have the 1TB OLED, only a 2TB drive is a real upgrade, which is why three of our five picks are 2TB.
3. Crucial P310 2TB (2230): Best SSD for Steam Deck OLED
The Crucial P310 2TB keeps the same 7,100MB/s read and 6,000MB/s write ratings as the 1TB model but doubles the space. Crucial names the Valve Steam Deck, ASUS ROG Ally, Microsoft Surface and select Dell laptops, and builds it with Micron G8 NAND and thermal control.
4. TEAMGROUP MP44S 2TB: Best Cooled 2TB for OLED
The TEAMGROUP MP44S 2TB puts 2TB on a 22 x 30mm board with reads up to 5,000MB/s and writes up to 3,500MB/s. TEAMGROUP describes it as a top choice for Steam Deck capacity upgrades and uses a heat dissipating graphene label. When we checked, TEAMGROUP itself was the seller.
5. WD_BLACK SN770M 1TB: Best 1TB for OLED
The WD_BLACK SN770M 1TB is the first M.2 2230 drive in the WD_BLACK line. It reads at up to 5,150MB/s on the 1TB and 2TB models, names the ASUS ROG Ally and Valve Steam Deck, and adds nCache 4.0, DirectStorage support and a 5-year limited warranty.
6. Addlink S91 2TB (2230): Best Slim 2TB Option
The Addlink S91 2TB reads at up to 5,000MB/s and writes at up to 3,200MB/s. Addlink lists HMB, SLC caching, thermal throttling and SmartECC, gives the size as 30 x 22mm with a 2.15mm maximum height, and says it fits select Steam Deck and ROG Ally models, so check yours first.
7. Fikwot FX953 1TB (2230): Best Budget OLED Upgrade
The Fikwot FX953 1TB uses PCIe Gen4 with reads up to 5,000MB/s and writes up to 3,100MB/s. Fikwot covers it with a graphite heat dissipation sticker, names the Steam Deck and ROG Ally, and backs the 1TB model with a limited warranty of up to 5 years or 320TBW.
How to Choose an SSD for Steam Deck OLED
Single-sided M.2 2230
iFixit describes the OLED drive as a single-sided M.2 2230, so stick with thin 2230 drives.
Go to 2TB on a 1TB OLED

Check Addlink's fit note

Plan the reinstall
A new SSD needs SteamOS installed with Valve's SteamOS recovery instructions.
