I see the term "Gb/s" on so many storage devices but what does it mean? Does it have to do with how fast the storage communicates with the motherboard? I have seen for example a Samsung 850 EVO with 540 MB/s write and 520 MB/s but has 6Gb/s read which i understand but than i see something like an M.2. with the same Read and Write as the Samsung 850 EVO except the Gb/s on this is 32 Gb/s instead of 6 Gb/s like the Samsung 850 EVO. I thought that the only thinkg that determines how fast a storage device works is the Read and write so does Gb/s matter just as much, is there a noticeable difference between 32 Gb/s and 6 Gb/s?
