With the BX100 we have another very good product for the price which is able to sport very good read speeds and decent writes for the 250GB model, while the 500GB and 1TB versions have even higher rating write speeds. For conserving the costs, the manufacturer has used an aluminum chassis with no screws, but the build is high quality and the internal PCB is kept steady and secure inside. While BX100 does come initially in a 7mm format, we are getting a free spacer with adhesive in order to able to mount it on more systems.
