A Reddit user developed a game cartridge system for Steam using individual SATA 2.5-inch 128GB SSD drives, allowing for tangible management of game libraries. This system, created by u/Jibril-sama, directs Steam to the corresponding game page upon SSD insertion and operates on a Linux base, with Windows compatibility lacking auto-navigation. Another user, u/halcyonforeveragain, showcased repurposed SD cards for use with the Steam Deck, enhancing game transfer capabilities. However, modern titles may require SSD performance for optimal gameplay, as traditional hard drives and standard SD cards may not meet the necessary speed. The cost for a 128GB SD card and USB4 card reader is about USD, while a 128GB SATA SSD with a docking station costs approximately USD. Customizing cartridges with art or labels is also suggested for a personalized gaming library.
