Product Introduction

Overview

JMS586R is a bridge controller between a USB host and two storage devices with a PCIe interface. The upstream port supports USB connectivity and is compliant with the USB 3.2 Gen 2x2 standard with data rates up to 20Gb/s. The downstream port supports two PCIe NVMe Gen3x2 ports. They can be connected to PCIe NVMe storage devices at data rates up to 32Gb/s, such as SSDs and memory cards. JMS586R supports the RAID0/1/JBOD function, which can improve the performance and reliability of the storages. In addition, the port multiplier function can be a cost-effective and convenient solution to expand the scalability of storage.
