Disk speed is typically measured using decimal prefixes. MiB is a binary prefix, and MB is a decimal one.
@JonMagon Thanks for the clarification. The transition is still in progress on most systems, so it is sometimes not as obvious.
It is more like a discussion.
I have a bunch of machines and I always do some benchmarks when I update them and compare/check performance results. I use KDiskMark when possible. For a short time we can see real binary units (like GiB) when set block size. BUT the measurement is still shows in MB / GB.
Since most OSes partially adopted both decimal and binary units it is a bit confusing to figure out which unit used actually. Back in my brain MB will remain as a binary unit but since both are commonly used I'm not sure sometimes what actually the programs use. It would be good to clarify what MB/s is. I prefer the binary unit but both can be useful.
