Those figure rounded for simplicity, but very close, Gbps to MB/s
It is very confusing... bits/sec vs Bytes/sec do some Googling Gbps to MB/s
Example
SATA 1.5Gb/s (aka SATA/150)
1,500 MHz embedded clock
x 1 bit per clock
x 80% for 8b10b encoding
/ 8 bits per byte
-----------------------------------
= 150 million Bytes per second
in other words:
150,000,000 Bytes per second
/ 1,024
----------------------------------
= 146,484.375 KiloBytes per second
=~ 146,484 KB/s
146,484.375 KiloBytes per second
/ 1,024
----------------------------------
= 143.0511474609375 MegaBytes per second
= 143 MB/s
