Rtl9210b Datasheet 2021 Jun 2026

The Realtek RTL9210B is a USB to SATA/PCIe bridge controller. In practical terms, it's the "heart" of countless external SSD enclosures. Its primary role is to translate data between a computer's USB port (USB 3.2 Gen 2) and an installed M.2 SSD, which communicates via either the PCIe (NVMe) or SATA protocol. It essentially allows your internal solid-state drive to function as a high-speed, plug-and-play external device.
