Terminology: opposite of "zero copy"?

Question

We're benchmarking some code that we've converted to use sendfile(), the linux zero-copy system call. What's the term for the traditional read()/write() loop that sendfile() replaces? I.e., in our report I want to say "zerocopy is X millisecs, and ??? is Y millisecs." What word/phrase should I use?

Programmed I/O (PIO) would be appropriate, I think.
