Score 7.6 / 10
Average of substance, design, and value.
IP68 sealing and MIL-STD-810H shock protection undercut every rugged rival at roughly $90/TB. Cache-dependent design means post-burst speed drops near 250MB/s—fine for quick transfers, not repeated 300GB+ jobs.
$90 typical
This is the budget recommendation because the low price buys real hardware: a metal heat-spreading case, IP68 sealing, MIL-STD-810H shock protection, a native USB controller and large cache. Its important limitation is candid: it is cache-dependent, so it is not the choice for repeatedly writing hundreds of GB.
It is a heat spreader as well as the structural shell.
Essential to retaining IP68 dust/water protection.
Compared with 8 other products in edition 1.

Small, brushed-metal, extremely clean-looking object; the rubber port cap is a minor fuss but makes sense for a drive built to get wet or dusty.
Five-year warranty; protect and fully close the port cap to preserve the ingress protection. QLC/cache behavior makes it better for intermittent than write-heavy duty.

Large cache holds roughly 1,750MB/s initially but native post-cache speed can fall to about 250MB/s.

20Gbps needs USB Gen 2x2; common 10Gbps hosts cap it lower.

SM2320-class native USB design, but cache behavior indicates QLC-oriented tradeoffs.
