Description
JMS561 USB3.0 to Dual SATA GenIII Ports Bridge Chip^^
Overview^
JMicron JMS561 is a Supper Speed to Dual SATA GenIII Ports bridge chip. It integrated three 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 JMS561 is able to reach a data transmission rate above 400M bytes per second when paired with an SSD module using JMicrons 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 JMS561, increased the data transmission rate by as much as 30%.^ JMS561 has passed the USB-IF test procedure for USB3.0 products and it won the Windows Hardware Certification approval.^ ^
