Raw numbers from validated tests (derived from the electrical table in the datasheet):

The RTL9210B-CG serves as an intelligent hardware bridge between modern storage media and universal USB host controllers. The chip's primary distinction from standard bridges (like the single-protocol RTL9210 or ASMedia ASM2362) is its .

The controller supports . However, this feature is rarely enabled in standard consumer enclosures. It typically requires specific firmware and host software to manage the encryption keys.

is highly power-efficient, reaching surface temperatures significantly lower (e.g., 42°C vs. 58°C) than competing ASMedia or JMicron controllers during sustained loads. rtl9210b datasheet

: Supports Bulk Only Transfer (BOT) and USB Attached SCSI Protocol (UASP) for improved data transfer efficiency.

: The controller utilizes shared high-speed pins to route either PCIe Gen3 x2 or SATA III signals depending on the drive logic level detection.

Dedicated differential pairs for USB 3.1 high-speed Tx/Rx signals, as well as CC1/CC2 pins for native USB Type-C orientation and power delivery negotiation.
