Typically under 2.5W during heavy NVMe read/write cycles. The controller is designed as a bridge between USB 3
The Realtek RTL9210B represents a mature and well-executed bridge controller design that successfully addressed the market’s need for a universal M.2 SSD interface. Its dual-protocol support (NVMe + SATA), robust feature set, competitive performance, and active firmware development made it one of the most significant bridge chips of the 2021 timeframe.
Enclosure controllers are notorious for running hot and draining laptop batteries. The RTL9210B addresses this through dynamic power switching: The Realtek RTL9210B Go to product viewer dialog
The client wept with joy. He got his thesis back.
Newer firmware updates around 2021 aimed at managing heat more effectively, which is critical for high-speed NVMe drives in compact enclosures.
