5G is 2.5 times faster . There is also going to be some loss from overhead. Not accounting for that, 2.5 gigabits (Gb) is equivalent to 312.5 megabytes (MB), whereas 1Gb is equivalent to 125MB. In terms of real world performance, Asustor’s own testing yielded read and write speeds of 283MB/s and 256MB/s, respectively.
