Silicon Motion's portable SSD solution is a single-chip solution equipped with a USB 3.2 Gen2 x 2 interface with 20Gb/s bandwidth, with the fully integrated hardware and software solution. It enables the ultra-high speed data transfer between PC and external portable SSD while enabling new SSD designs to take full advantage of high-density NAND Flash, including the latest generation of 12x-layer QLC NAND.
Because it can interface directly to the host without the need for an external bridge chip, it enables manufacturers of external portable SSDs to reduce system size and lower their Bill-Of-Materials (BOM) cost.
