Do you really work with memory, storage, and bandwidth? If so, have you EVER run across an instance where memory, storage, or bandwidth were referred to in millibits? Memory, storage, and bandwidth are extremely important in my job, though not my direct focus, and I can say over 50 years as a sysadmin and coder, I have never encountered “mb” and had it actually mean “millibits”. Literally not once. Now “Mb” definitely has some ambiguity (in bandwidth, it’s used for Megabits, and in memory/storage, it’s more often than not a typo of MB), but “mb” actually meaning “millibits”? No, friend. Just no.
