Includes hardware acceleration for sequential and random data rates and support for external SPI NVRAM. Known Implementation Details & Issues
The JMS579 is built on a highly integrated architecture that minimizes external component requirements, making it ideal for cost-sensitive and compact storage designs. jmicron jms579
Historically, bridge chips were a bottleneck. They were slow, ran hot, and often capped your transfer speeds. The JMS579 was a significant step forward because it was designed to handle the full bandwidth of SATA III (6Gbps) without choking. They were slow, ran hot, and often capped
The is a USB 3.1 Gen1 (5Gbps) to SATA 6Gb/s bridge controller. It is primarily found in external hard drive enclosures, most notably recent generations of Western Digital (WD) My Book and WD Elements portable drives. Key Technical Specifications Interface: USB 3.1 Gen1 to SATA III (6Gb/s). It is primarily found in external hard drive
