WHY THE PRICE IS JUSTIFIED

It spends money on Micron TLC, a mature native-USB controller, five-year coverage, aluminum heat spreading, and IP55/2m protection—not inflated peak-speed claims. Dong Knows copied a 100GB-plus file with no slowdown and reported it ran cool.

MATERIALS

Top shellAnodized aluminum

Acts as a heat spreader and gives the small body real stiffness.

BaseRubberized polymer

Adds non-slip grip and impact buffering.

FlashMicron 176-layer TLC NAND

Better endurance and post-cache behavior than budget QLC designs.
