| Doing math and converting kB to Mb and so on gives me a headache, and I can't be particularly certain that I'm doing it right. Therefore, these are the speeds in **binary bytes**, as in, this is what I use in [[dvd_info]] and [[bluray_info]] when deciding how much memory to allocate or drive speed to run at, as in an **char**. | Doing math and converting kB to Mb and so on gives me a headache, and I can't be particularly certain that I'm doing it right.
