Also http://www.iozone.org/

Really, iozone isn't a benchmark as much as the "engine" of
a benchmark.  It has so many options that you can use it
to build higher-level, more intelligent test suites by invoking it
in specific ways.  read/write, mmap, MS_SYNC, MS_ASYNC, O_DIRECT,
aio, O_SYNC, fsync(), multiple threads, ...
