The UnionSine 500GB external hard drive is a slim 2.5-inch HDD that connects over USB 3.0 with read speeds up to 125MB/s and write speeds up to 103MB/s. The JMicron 578 controller keeps noise minimal during operation, and the aluminum anti-interference layer around the chip helps with both heat dissipation and data protection.
