The external storage market has experienced rapid growth over the last few years, particularly in the retail consumer segment. It has been fueled in part by advancements in bus-powered flash-based storage devices.
Thunderbolt SSDs are at the top in terms of both performance and price, but the last few years have seen various high-end portable SSDs with a USB interface. The USB 3.2 Gen 2x2 (20Gbps) ecosystem has been slowly gaining traction, with Kingston's XS2000 portable SSD being the latest to join the device lineup. Based on Silicon Motion's new SM232x family of UFD (USB flash drive) controllers, the product family offers full Gen 2x2 performance while consuming a fraction of the power needed by similar solutions currently in the market.
Silicon Motion sent across the bare reference board used inside the Kingston XS2000 to put through our rigorous direct-attached storage testing routine. Read on for our evaluation report of the SM2320XT reference design.
