The first, only since the second maximum 1/7 is created because the connection no longer produces.
NVMe stands here: up to 3500MB/sec
the SATA normally creates up to 500MB/sec
In practice, the difference will hardly be noticed
The SSD in the M.2 factor with NVMe protocol is significantly faster than an SSD with SATA protocol (theoretically 20 vs. 6 Gbps).
