   I have other uses for my RAM than acting as a crutch for a 
poorly-designed disk subsystem.

   Hmm...further, I'd rather just have my drives reorder their writes.  
Oh, I forgot...IDE isn't smart enough to do that yet, is it?

   Shit, I had an SMD disk subsystem on a VAX nearly fifteen years ago 
that could do that.

   Ok, I could buy that.  But what about NetBSD...FreeBSD...Linux..on 
Alphas and x86 boxes alike...all of which I've seen perform better with 
a real disk subsystem?  My observations are based on a lot more 
observation than dicking around with OS X for the past few 
months...otherwise I wouldn't take such a strong stand about it.

   My TiBook has an IDE drive...I don't see anything in the message 
buffer or in syslog about it though...? :-/
