No. Just no. Don't use crappy software when you want to get your facts right.
The hw bandwidth is 7MB/s read/write. Use 'bustest' to check how good your cpu is at getting the full bandwidth (I can't remember what the plain 1200 does, but it should be close to the theoretical max).

Just looking at the sysspeed page linked shows so many baloney numbers that you have to shake your head. Please don't use syssped if you want to check Amiga memory speeds.

I think 0.19 is the most up to date version of bustest btw.
Never had a 1200 so I only remember my 4000/CS060 which did near as much 7MB/s and something like 40-50MB/s to fastram. (Been a while since it was alive so I can't say for sure about the fastram.)

A number of cpu cards handled write-combining and pipelining/delayed writes pretty bad and had worse numbers than a stock machine...
