At just 80mm square, the PC60 is one of our most portable-friendly portable SSDs yet. It fits snugly in the palm of a hand and comfortably slides into a pocket, unnoticed, thanks to its slim 11mm profile. It’s also surprisingly lightweight. The shock-resistant structure, which can withstand minor drops and bumps, and the convenient keyhole design, which allows it to easily attach to keychains or bags, both complement its intent to be an on-the-go back-up storage solution.
