Sorry - don't really care about the how or why, was just after a simple
rough and ready metric to see if my SSD was excessively slow.

Steve's numbers suggest that 180 MBytes/second is indeed sub-par, and
similar measurements I got from the guys in #nzlinux on the freenode IRC
channel confirm that my SSD is slow.

Now I have to see if it was always that slow... My recollection is that
it did get 270 Mbytes/second when it was new, so I will investigate if
trim is working as expected.   Could also be the running load so I'll go
single user and do some more testing
