    • Controller Vendor: Silicon Motion, Inc. (SMI).
    • The Code (1166682780): In most USB database logs, this string corresponds to the SM3267 or SM3268 series controller. These are high-speed, low-cost USB 3.0 controllers capable of read speeds up to 150 MB/s and write speeds up to 60 MB/s (under ideal conditions).
    • The "Extra Speed" Tag: A-Data labels some of these drives as "High Speed" or "Extra Speed" because the SMI controller supports Dual-Channel mode and DDR (Double Data Rate) NAND flash.
