“divide by ten to get the real throughput in gigaBYTES.”

Actually devide by 8, not 10. but agreed.

8 bits to the byte.

For storage, that's true. For serial transmission, though, each byte requires a 'start' bit and a 'stop' bit. It's long been a common practice to divide by 10 rather than 8 to convert a serial bit rate to a byte transfer rate.

No... bits is the rate... bytes are the data. You have 1 start bit and 1 stop bit for every 8 bit byte... equals 10.
