The blocks are a bit uninteresting:
7+0 records in 7+0 records out 6+0 records in .... 11+0 records out 8+0 records in 8+0 records out 2+0 records in ... 2+0 records out 15+0 records in 15+0 records out --- Tells me nothing -- not size of recs, nor time.. nothing interesting.

Side note: ----------- Which, BTW, is consistent using with use of other non-metric units, like hours (you don't hear about kilo-hours or kilo-minutes) because the units are not a multiple of 10 that is appropriate to use with Metric prefixes). I think the litmus test is whether or not the unit being used is some power of 10 (and no arbitrary constant 'k' to convert it to a metric unit. Thus bits, being a single, recognizable flux change on disk correspond on a 1:1 basis (sans compression) to flux changes, and the number of flux changes one can pack into a cm^2 is a pure calculation with base-10 metric units. VS. Speaking of 'Bytes', or Sectors, one is no longer speaking of a direct metric unit, but of a convertible one. It is rare and not official practice to use metric prefixes with non Metric units. As bytes are not a metric unit, using base-10 metric prefixes shouldn't a point of discussion or contentions. Bytes infer base-2 multiple quantities that can only be precisely specified by base-2 prefixes.
