For the bus, yes. Solid state memory devices excel at sequential reading of blocks of their memory and transfer to the bus. Where they loose significant transfer rate speed is with random read and writes - I/O. Here the rate is controlled by the size of contiguous blocks transferred, the queue depth, location, and cache size. If you look up reviews of various brands of nvme and ssd devices serving as random access disks, you will see that the larger the total memory - 128 GB, 256, 512, 1 TB, 2, 4, the faster overall bandwidth will be because of the ability to run parallel operations, particularly random I/O. Some I/O controllers are faster than others as well. So what difference does it make ? For most general users with web and office type uses, not much once shifted to either ssd or nvme disk devices. For applications like databases or servers, it can make a difference.
The most noticeable difference for general users is at OS startup and for program/app startup. Both will take less time and feel “snappier”. After initial loading of the programs, the accesses shift to being more random in location on the device and in size of data or program code being read or written. This is still faster than on a spinning disk, but the real world feeling of nvme being faster than a sata ssd is less noticeable. It is faster though.
