Imagine you have a spare M.2 SSD. It could be a lightning-fast NVMe drive or a more common SATA drive. With an enclosure based on the RTL9210B, you can use either. The chip automatically senses the type of SSD you've installed and switches its internal protocol from USB-to-PCIe (for NVMe) to USB-to-SATA. This dual-protocol support is its killer feature, providing incredible flexibility and future-proofing.
