iozone, bonnie, bonnie++ and dd seem to give consistent result if the file size is less than 100MB but it is very inconsistent if I use file size > 1GB

I don't know if this is normal.

It's likely to be the result of caching - unless the tool explicitly clears all caches, then your test files need to be bigger than your potential cache size so as to flush out old data as you go.

WANTED: "Software CD ROM Kit" for Canon CLBP 360-PS printer (Canon part no RH6-3612, or possibly RH6-3810, or RH6-3610 might do). I've a dead HD and need this CD so I can replace the disk and re-install the printer OS on it. If anyone knows where I might get hold of one I'd be grateful - requests to Canon drew a blank, it's been out of support for years. Alternatively, if anyone has one of these and would let me image their hard disk ...
