Fujitsu's 65-nm MB86C30A USB 3.0-SATA Bridge chip looks to bring the full performance of SATA storage to USB. USB 3.0 specs up USB 2.0's 480-Mbit/s transfer rate to 5-Gbit/s transfer. This translates into 300 Mbytes/s versus USB 2.0's 37 Mbytes/s. This is also on par with SATA-ll's 3 Gbits/s with a typical throughput on the order of 260 Mbytes/s. This matching performance is key for external storage units. The chip also incorporates a 32-bit RISC processor and AES hardware encryption support, which allows full-speed, full-disk encryption. It additionally supports the latest 2-Tbyte hard drives. Configuration options are available via SPI serial flash. CPIO allows direct manipulation of peripherals such as status LEDs. Further, the chip employs a spread-spectrum clock generator to reduce electromagnetic interference (EMI).
