Silicon Motion has launched a new single chip for external portable SSDs, the SM2322, designed to support up to 8TB of storage along with data transfer rates of 20Gbps.
With the increase of AI-capable devices, high density and high-performance storage solutions are becoming more critical to consumers.
Portable SSDs powered by the new SM2322 controller are the only solution that offers low-cost, high-density and high-performance, making it the ideal solution for these applications.
Equipped with a USB 3.2 Gen 2×2 interface with 20Gb/s bandwidth and fully integrated hardware and software solution delivering peak sequential read and write transfer speeds of 2,100MB/s and 2,000MB/s, respectively, with up to 8TB capacity, SM2322 powered high-performance portable SSDs enable an ultra-compact and lightweight form factor.
The SM2322 supports the ProRes format and MFi specification for iPhone users while also being compatible with Windows, Android OS and macOS, making it an ideal high-density, high-performance portable storage solution for AI smartphones, HD content creators and gaming enthusiasts who require high-density, high-performance portable storage.
By eliminating the USB bridge chip required in traditional designs, the single-chip solution reduces both the Bill of Materials (BOM) costs and power consumption.
According to the company, the new SM2322 upgrades external portable SSDs with higher performance and larger capacity using Silicon Motion’s proprietary NANDXtend 4KB LDPC error-correction technologies to improve the endurance and data retention of 3D TLC/QLC NAND.
It provides data integrity through SRAM ECC and end-to-end data path protection.
In addition, the SM2322 delivers the highest level of data security by providing AES 256-bit encryption, fingerprint security and full compliance with the Trusted Computing Group (TCG) Opal specification to meet the high-security standards.
“The proliferation of AI smartphones and handheld gaming devices has exponentially increased the demand for managing large digital video and photographic content,” said Nelson Duann, Senior VP of Client & Automotive Storage Business at Silicon Motion.
“AI inference will generate extensive data, making high-capacity storage even more important.
“The new SM2322 now sets the bar even higher, introducing enhancements to support the higher speed USB3.2 specifications and providing greater capacity, catering to the needs of the AI era for large-scale digital media content storage and access.”
