With append blank, we're writing blanks into the fields and indexes, then during a replace we're doing it again (and potentially reshuffling some of the b-trees in some of the indexes). So it's not one write vs two writes, it's n writes vs 2*n writes.

Can't find that in help - and with buffering you are actually delaying the write until tableupdate(), so the difference between the two actually vanishes. VFP only has more work to do with its buffers meanwhile, if you append/replace.
