Score formula
(Sequential Speed x 0.30) + (Durability & Build x 0.20) + (Capacity Options x 0.20) + (Real-World Value x 0.20) + (Compatibility x 0.10)What each component measures
| Component | Weight | What it measures |
|---|---|---|
| Sequential Speed | 30% | Rated read/write and how much of it survives a real host port — 1,050MB/s on 10Gbps to 2,100MB/s on 20Gbps across this field |
| Durability & Build | 20% | Shell material, shock resistance, and IP dust/water rating — what survives a shoot bag versus a desk drawer |
| Capacity Options | 20% | Range of sizes offered, from a pocketable 1TB to the 4TB ceiling only the Crucial X10 Pro reaches here |
| Real-World Value | 20% | Delivered capability and capacity-per-dollar against the current Amazon price, not the headline sequential number |
| Compatibility | 10% | Host-port and cross-platform reach — USB-C, USB-A adapters, and Windows / Mac / Android support |
How to read the number
A 9.0 on the Samsung T9 means the parts you'll feel every shoot all land: it reads at its rated ceiling on a 20Gbps port so a full card clears in minutes, its rubberized shell survives being tossed in a bag, and its encryption keeps client work private. Speed carries the most weight because it is the thing you wait on daily. The SanDisk Extreme Pro's 8.8 is value and ruggedness in action — IP65 and the lowest total outlay — trimmed only by its earlier-firmware history, which the current SKU addresses. Scores synthesize TechRadar, PCMag, PCWorld, CNET, ZDNET, Engadget, SlashGear, and Notebookcheck coverage.

How DeskGearHQ scores anything
DeskGear Portable SSD Score is a category-specific composite. It sits on top of the site-wide framework: DeskGearHQ does not run a testing lab, and every score is an editorial synthesis of named expert sources, manufacturer documentation, and practitioner-community signal — explicitly not a laboratory measurement. The base DeskGear Score, its factor definitions, the full source stack, and the refresh policy are documented on the methodology page.
