The Steam Deck does come with a UHS-I microSD card reader for expandable storage, allowing you to add more (though also slow) storage. The 'embedded' part of the name is quite literal.

In the case of eMMC we already know it's impossible. It seems that you won't be able to get inside the Steam Deck to swap out the NVMe storage, at least without some serious disassembly. The Steam Deck’s LCD screen runs at 1200x800 at 60Hz, and it looks really good. You can check out our Surface Go review to see how performance compares between eMMC and NVMe storage. Using the Steam Deck exclusively for a few days makes the Switch feel like a microconsole. If you want your games to load fast, you will definitely want to go with one of the NVMe SSD options. Speaking on performance, there is a significant gap between eMMC and NVMe. The Steam Deck, which you can only purchase from Steam itself, currently comes in three different options, each with varying levels and types of internal storage.

For a handheld device, that's especially important. eMMC storage isn't as fast as NVMe SSD storage, but it does generally draw less power. A larger SSD is always recommended.ĮMMC storage - which stands for embedded MultiMediaCard - is generally used in cheaper electronics as a way to keep prices down. PC gamers already know how quickly storage fills up.
