Review on 💡 THKAILAR USB 3.0 Flash Drive 128GB: Ideal Storage Solution for Students, Business Travelers, and Gamers; Compatible with External Devices, PS4, PC, Laptop; Swivel Design, Blue LED Indicator by Robert Hayes

This product worked fine on my PS4 but only after I reformatted it to Fat32. If you don't reformat it won't work (at least it doesn't work for me). This is more Sony's fault than the flash drive manufacturer's. Sony had to develop software to work with regular flash drives, not ones that need to be specially formatted with small partitions.
