Essential Factors We Consider
When choosing an M.2 SSD, we evaluate several key factors: speed (measured in MB/s for read/write), capacity (how much data it can hold), form factor (most are 2280, meaning 22mm wide and 80mm long), interface (Gen3, Gen4, or Gen5), and thermal performance (especially important in compact builds). We also consider brand reputation, warranty, and real-world user feedback to ensure reliability.
Budget Planning
M.2 SSDs range from around $50 for a 500GB Gen4 drive to over $200 for high-capacity, high-speed models. For most users, a 1TB Gen4 SSD offers the best balance of speed, space, and cost. Gamers and creators may want 2TB or more, while budget builders can start with 500GB and expand later.
