BULLSHIT. They are in fact limited by the speed
at which the sectors move under the heads.

Thanks for that completely superfluous proof that you
have never had a fucking clue about anything at all, ever.

Yes, but that isn't because of the two separate interfaces.

Utterly mangled all over again.

More fool you. It makes a hell of a lot more sense to have
a lot more physical ram so the swap file doesn’t get used.

That only matters when moving large
files from one 'drive' to another.

But have never understood the basics like the FACT that
the thruput with stuff that isn't cached is determined by
the rate at which the sectors move under the heads with
modern fast seeking drives.

The world has moved on on that LONG ago now.

Only for stuff like moving large files around
which you shouldn't be doing in the first place.
