As of April 2026, not all M.2 SSDs sold are of the NVMe type, though they now dominate the vast majority of the market. M.2 SATA SSDs are still being manufactured and sold, primarily as budget-friendly options or for older systems that do not support the NVMe protocol.
Key Differences Between M.2 SSD Types
While they share the same physical form factor, they use different communication protocols.
M.2 NVMe SSD use the PCIe interface to connect directly to the CPU, offering massive speeds, often exceeding 7,000 MB/s on Gen 4 and even faster on Gen 5. They are the standard for modern gaming and professional workstations. M.2 SATA SSDs use the older SATA III protocol and are limited to a maximum speed of roughly 600 MB/s. They are mostly used to “revive” older laptops or in ultra-budget builds where high speed isn’t a priority.
Regarding Market Dominance, NVMe M.2 drives have captured over 70% of the total market share. Some projections suggest SATA market share will drop below 10% by late 2026. Production Shifts at major manufacturers like Samsung have reportedly begun halting or scaling back SATA production to focus on premium NVMe and AI-oriented storage. What about availability? You can still easily find M.2 SATA options from brands like Transcend, KingSpec, and Western Digital.
If you are buying a drive today, check the keying on the connector. M.2 SATA drives often have two notches (B & M keys), while modern NVMe drives typically have only one (M key).
