Framework sells the 2TB version of Western Digital SN740
Now that Steam Deck is gradually returning to a reasonable price, many DIY players even buy it to play mods, even if they don’t buy it to play games. A 64GB version of Steam Deck and a large-capacity SSD is the most basic way to play, but Steam Deck uses a relatively rare 2230 specification M.2 SSD. There are not many models on the market, and players who are not familiar with the market may not know which one to choose. As for Framework, which is known for making modular notebook computers, it has recently listed the Western Digital SN740 in its own store, which is currently a relatively good 2230 specification M.2 SSD.
Since Western Digital SN740 is mainly provided to OEM manufacturers, there is no retail version for now, so it may not be easy for players to buy.
Western Digital SN740’s native continuous read and write speed can reach 5GB/s, but the interface of Steam Deck is PCI-E 3.0, so the actual speed is only half, but it is already much faster than the original 64GB eMMC. After replacing the SSD, you need to restore SteamOS manually. Of course, you can also install Windows 11 directly.
