The core function of the RTL9210B is the translation of the NVMe command set over the PCIe bus to the Mass Storage class (MSC) protocol over USB. Unlike older translation layers that often incurred significant latency, the RTL9210B utilizes a hardware-based translation engine. This allows for near-native latency performance, which is critical for random I/O operations often neglected in external drives. rtl9210b datasheet
is a versatile USB bridge that connects a USB device to both and SATA controllers. It’s the "brain" inside many high-performance M.2 external drive enclosures, allowing you to swap between different types of SSDs without changing hardware. Key Technical Specifications: (6 pts) The datasheet lists built-in diagnostic registers
: Supports PCIe Gen3 x2, providing up to 16Gbps internal bandwidth. It is compliant with NVMe Base Specification Rev. 1.3. The core function of the RTL9210B is the
The chip uses the PEDET (PCIe Detection) interface of the M.2 mechanical connector to automatically switch between USB-to-PCIe and USB-to-SATA modes based on the installed drive.
