The Bolt B80 USB 3.1 External SSD from Silicon Power does sport a premium look thanks to the aluminum construction but is also easy to carry along. It comes with military-grade shockproof protection, but also rubber covers/gaskets in order to prevent water and dust penetration. For signaling data transfer activity, the product is provided with a white LED and its modular design along with the easy disassembly procedure does allow the user to replace the mSATA SSD with any other model/capacity.
