Device performance should be specified as a minimum assured level of

peak values are meaningless.
Seems a little pessimistic to me. Certainly minimum assured values are
the basic thing people need to know, but reasonably characterized peak
values can be valuable, if the conditions yielding them match possible
application usage patterns.
Agreed. It is useful to know minimum, median, and peak values. If
there is a peak, it is useful to know how long that peak may be
sustained. Intel's specifications have not characterized the actual
performance of the device at all.
The performance characteristics of rotating media are well understood
since they have been observed for tens of years. From this we already
know that the "peak" performance of a hard drive does not have much to
do with its steady-state performance since the peak performance is
often defined by the hard drive cache size and the interface type and
