Rtl9210b Datasheet Work <Validated · 2024>

The controller can interface with external DRAM (DDR3/DDR4). This acts as a cache buffer to improve random read/write performance and extend the lifespan of the SSD by reducing write amplification.

Empirical testing of the RTL9210B reveals a thermal design power (TDP) that requires consideration. Under sustained sequential loads (such as large file transfers), the controller can generate significant heat. Without a thermal pad connecting the chip to the enclosure casing, the RTL9210B has been observed to initiate thermal throttling, dropping transfer speeds from the 1,000 MB/s - 1,050 MB/s range down to lower thresholds to protect silicon integrity.

The RTL9210B is notable for its active third-party developer community, which has filled in many of the gaps left by the official documentation.
