Gaming accessory company XPG is exploring the idea of turning a gaming mouse into something more than that. The XPG Vault Gaming Mouse is a wired USB-C mouse equipped with a high-speed SSD drive to offer you a "gaming library in the palm of your hand." This concept mouse supports up to 1TB of memory that can run at a speedy 985 MB/s. XPG's Prime Software Ecosystem app controls this storage.
While it looks like your typical, unassuming mouse, it would need a stout, sturdy USB-C cable to run. But as Engadget pointed out, this high-speed storage frees up a USB slot usually taken up by a wired mouse. XPG didn't share anything else about the mouse's specs. But it is a prototype, so we aren't too surprised about that.
