Backward compatible with SATA 3 Gb/s and 1.5 Gb/s. · Manufacturer specification · Requires compatible SATA data and power connections; link rate is not an application-performance result.
Manufacturer specification · Host support and available lanes determine operation; interface generation is not an application-performance result.
Check the connection before the capacity. M.2 NVMe modules and 2.5-inch SATA drives are not interchangeable. Check the host’s protocol, slot or bay, power connection and clearance. Rated speeds use different test systems; we do not turn them into a speed score or overall winner.
15 verified differences, most decision-relevant first. 7 are also drawn in Visual facts above. Missing information stays separate.
