:Hm. But I'd think that even with modern drives a smaller number of bigger

As long as you do not blow away the drive's cache with your big I/O's,
and as long as you actually use all the returned data, it's definitely
more efficient to issue larger I/O's.
If you generate requests that are too large - say over 1/4 the size of
the drive's cache, the drive will not be able to optimize parallel
requests as well.
