DRIVE: I want to upgrade the drive in my PS4. With new content going digital, I'd like to measure / benchmark speed increase and noise reduction for games stored on the device itself. Also, the base 500GB drive is just not quite enough, so an upgrade in capacity would be useful.
POWERBANK: First world problems I know, but with the PS4 came its controller and a wireless headset. Both of these need regular feeding, often at times when I need them most. Having a device I can use that's small / portable to charge them as they're being used would let me play longer - and truly develop those epic cases of OOS.
