The SM3265AC is a high-performance USB flash drive (UFD) controller manufactured by , a global leader in NAND flash controllers. It is part of SMI's SM3265 series, which includes the SM3265AB and SM3265AC variants. This chip is specifically designed for the latest USB 3.2 Gen 1 standard, enabling data transfer rates of up to 5 Gbps, which is ten times faster than USB 2.0. The controller is integral to numerous commercial USB drives from brands like Transcend, Apacer, and Lexar, as well as custom-built solutions for specialized applications.
In reality, the SM3265AC is a workhorse. It supports TLC and QLC NAND. It is cheap to manufacture. That is its only superpower.
Plug the drive into a USB 2.0 testing slot while keeping the pins bridged.
It is worth noting that the SM3265AC is not designed for ultra-high-speed applications like external SSDs. Instead, its strength lies in balancing respectable read speeds (typically 80-130 MB/s) with broad NAND compatibility and low production costs.
