JMS562 Product Brief

JMS562 USB3.0 & eSATA GEN III to Dual SATA GEN III

Ports Bridge Chip

Overview

JMicron JMS562 is a Supper Speed & eSATA GEN III to Dual SATA Gen III Ports bridge chip. It integrated four

independent SATA channels and a micro-processor. With proper setting, the chip can be configured as 1 to 2- ports

Serial ATA III Port Multiplier or hardware striping & mirror. The JMS562 is able to reach a data transmission rate above

400M bytes per second when paired with an SSD module using JMicron’s JMF667 SSD controller. The readings were

measured by IOMeter, a gauge for storage device performance, with a variety of queue depths and worker number

settings, on a platform with an xHCI host on an Intel Panther Point C1 stepping PC, running Windows 8 Build 8315

Core 2. Enabling USB Attached SCSI Protocol (UASP) on the JMS562, increased the data transmission rate by as

much as 30%.

JMS562 has passed the USB-IF test procedure for USB3.0 products and it won the Windows Hardware Certification

approval.
