While the X9 Pro drive can be considered a good mainstream variant, the X10 Pro is really impressive in terms of both read/write performance for an USB 3.2 Gen2 2x2 drive, staying on top with other high-end models we have tested in the past. At its heart it does pack a Silicon Motion SM2320 controller and durable Micron 176L 3D TLC NAND ICs, which are able to hold a high transfer rate for quite a bit!
