I understand RMW perfectly well, thank you. You are not paying attention, 
apparently.

There are two issues.

1. There is a performance penalty for writes of < 4K due to RMW. But, as the 
very article you quoted notes, this isn't much of a problem since most I/Os are 
4K anyway. (In fact, it's my understanding
that -all- NTFS writes are 4K, since that's the NTFS cluster size--but I 
haven't been able to find confirmation of that this morning.)

2. RMW comes heavily into play when an I/O straddles two 4K sectors. This is 
problem for XP because it places the first sector of the primary partition at 
sector 63, which would mean that -all- 4K
I/Os straddle sectors. But what you do not seem to understand is that either 
the jumper settings or the disk utility fix this permanently by PHYSICALLY 
MOVING the first sector to sector 64. This issue
goes away, completely and forever. It is a dead issue. It has gone to join the 
choir eternal.

So, contrary to your assertion, the jumper settings do indeed "get around it", 
and the "bliss-based ignorance" is not on this end of the conversation.
