Despite being packaged as a handheld device, theSteam Deckis a powerful and versatile machine that can easily handle recently launched games. However, as with most current-gen hardware, the system’s storage space with big video games and apps will get used up.
The Steam Deck is available in two versions if users prefer the cheaper refurbished LCD options and the OLED version. The OLED model comes in 256GB, 512GB, and 1TB. The LCD model is also currently sold in three models offering different storage options. Users can buy the 64 GB, 256 GB, and 512 GB. All three versions are excellent choices, but the entry-level 64 GB model is unsurprisingly more limited in installing large games. Takingfree-to-playApex Legendsas an example, the game takes at least 70 GB to install, so the smaller model isn’t sufficient. Thankfully, there is a way users can upgrade their Steam Deck and increase its storage. This guide will explain the steps and items needed toexpand the Steam Deck’s storage space.

However, downloading games to the micro SD can be more time-consuming than if stored on the SSD. If one has a larger model, it’s ideal for storing smaller titles orplaying games with emulation on the Steam Deckfor older software.
How To Install A Micro SD Into The Steam Deck
The Steam Deck has a micro SD slot outside of the device. So there’s no fiddling around and taking the machine apart to expand the capacity and get more out of it. Use the following steps to install the new SD card:
That’s everything needed to expand the Steam Deck’s capacity. As mentioned above, be aware that downloading high-capacity games will take longer thanthe SSD, but playing the games from the card will give the user more than a satisfactory experience.
Connecting An External Hard Disk Drive
An external hard drive is an alternative method to installing a microSD card. However, it’s better to keep the Steam Deck docked anduse it like a desktop PCto do this.
