Yes, writes are buffered and written in a file-independent manner. The
write(3) syscall simply places the data to be written in the block
buffer, which the Linux kernel then writes to disk in an intelligent
fashion. So it should not matter how many files you are writing to,
the disk will still be used efficiently.
