The word "cluster" is usually used in the context of file systems on Windows. Other OS's don't normally use this word. But the meaning is the same as what I call I/O chunk size, which some people call file system block size, some call file system buffer size. I like to avoid the phrase "block size" because it may be confused with sector size (almost always 512 bytes in most traditional OS's).

There's no file system. It's up to the program that determines how much you want to write at a time, as "xxx" in 'dd bs=xxx'. |
