That's simply too much information to store and stringgrid have to
have support for other things like the hability to change any row
height, so it's more of general purpose.
I guess we need to split the string handling from the component.
Another kind of grid is needed, a virtual grid, something like a
dbgrid but not tied to db.

Did you tried the test by filling a stringlist or the fastest string
list available?, I think that would be best we could achieve using
lists?
I think your test shows stringgrid is not a good candidate if used in
the standard way, if strings are stored in other place, not in the
grid, any grid could be used to draw the content simply by handling
the scrollbars and OnDrawCell, but this require more work of course
