Vice-versa I think you meant with bandwidth measured as base2 bytes and HDD sizes
measured in pseudo base10 bytes for marketing reasons as you said.
Of course in modem days, it was /10 since there were start & stop bits. Technically
speaking it's /8 for raw data transfers not effective data throughput which is lesser
due to packet & protocol overhead but close enough.

Small correction (so we can get accurate speed measurements): for bandwidth
purposes, it's not a 10:1 ratio, it's 8:1.
So 1MB/sec = 8Mb/sec (1 Megabyte = 8Megabits).
Or if your cable modem gives you 8Mbits/sec down, that's actually 1
Megabyte/sec, and if it's 10 Mbits/sec (Mbps), that's 1.25 Megabytes/sec
(MBps).
This is b/c bandwidth is measured in base10 (the decimal system), while
storage is measured in base2--ignoring cheating HD Mfrs of course who use
the decimal system to make their HDs seem bigger b/c they measure the
capacity they advertise in decimal while files and folder are still stored
in base2, which means my 1TB drive really stores 931GB of data...but
anywho...HTH!
