Silicon Motion Technology Corporation launched its new SM2320 single-chip high performance, lower power, and cost-effective solution for external portable SSDs.

The new SM2320 controller solution is designed with integrated hardware and firmware as well as high-level security features which meet the needs of game console users requiring high performance and the low power requirements of laptop users. The external portable SSD market is growing due to the performance, low power consumption, reliability, and portability of such devices enabled by NAND memory. Customers include Kingston Technology, which has designed SM2320 into its new XS2000 external portable SSD, as well as other module and NAND flash providers.

Silicon Motion’s unique SM2320 external portable SSD controller solution features a USB 3.2 Gen 2 interface, advanced SSD controller architecture, and four NAND channels, and delivers sequential read/write speeds up to 2,100 / 2,000 MB/s. By eliminating a USB bridge chip typically required in other more traditional designs, the SM2320 solution also lowers the Bill of Material (BOM) cost and power consumption. The SM2320 controller solution includes Silicon Motion’s NANDXtend ECC end-to-end data path protection and supports up to 4TB of capacity using the latest TLC and QLC NAND. Additionally, the SM2320 controller solution supports the highest level of data security by providing AES 256-bit encryption, full compliance with the Trusted Computing Group (TCG) Opal specification, and auxiliary Fingerprint Security support.
