How I chose and rated these products

The score has three parts. Technical (60%): the verified characteristics, at least 2 per product; a product with fewer verified figures gets no score. Reviews (20%): the scores of reviewers and stores, each with its source; when they are missing their weight moves to technique, never to price. Price (20%): the lowest verified price in the market, never more than a fifth of the total. Weights and thresholds are declared editorial choices, not invented quality measurements. Initial sample of three verified Italian retail variants; only declared specifications and observed prices are compared. Manufacturer and retailer sources carry separate confidence levels. No benchmark, real-world performance, quality, reliability, actual consumption or universal compatibility has been tested. Shipping is unverified; the sample is not the whole market. Criteria and weights: Memoria massima dichiarata (GB) (30%), Slot M.2 dichiarati (30%), Observed price (40%).
