Rtl9210b Datasheet //top\\ · Best & Complete
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.
The RTL9210B implements aggressive power gating. The datasheet indicates support for multiple low-power states, including and ASPM (Active State Power Management) for the PCIe link. This allows the drive to enter a deep sleep state when idle, significantly reducing heat generation and preserving the lifespan of the attached NAND flash memory. rtl9210b datasheet
