¡El Realtek RTL9210B-CG is a USB (Universal Serial Bus) bridge that combines a USB device with both a PCI Express (PCIe) controller and a SATA controller. Via the PEDET interface of M.2 mechanical, the RTL9210B-CG can auto switch USB-to-PCIe mode, or USB-to-SATA mode. ¡El RTL9210B-CG supports USB 3.1 GEN2 (Super Speed Plus). It is compatible with USB 3.1 GEN1 (Super Speed), USB High Speed, and Full Speed. It can work normally with auxiliary power. ¡El Mass Storage transaction supports both Bulk Only Transfer (BOT) and USB Attached SCSI Protocol (UASP). For USB, it provides up to 10Gbps bandwidth. In USB-to-PCIe mode, the RTL9210B-CG supports PCIe Gen3 x2. For PCIe, it provides up to 16Gbps bandwidth. It has full backward compatibility for PCIe Gen2/Gen1 and link width 1 lanes. It supports PCIe 3.0 LTR (Latency Tolerance Reporting). To further reduce power consumption, the RTL9210B-CG supports link power management (PCIe L1. Off and L1. Snooze), PCI MSI (Message Signaled Interrupt) and MSI-X.
