Offhand, I don't recall the exact table, but...
At around the 512 MB, your cluster size slips into 16K--otherwise, its 8K
all the way down to about 250 MB, at which point below that its 4K. From
512-ish to a touch over 1 GB, its that 16K--over that 1 GB size (I think
the exact is 1024 MB) you're suddenly in the 32K cluster range--ouch!
Your partitioning scheme seems like a neat plan, but personally, I think
it would be a PITA--I'm all for saving space lost to big cluster sizes, but
I'd prefer to minimize the number of drives too. Your mileage may vary,
but if it were me, I'd partition into two--you pick the sizes, but 8K
clusters is about as reasonable as it gets while still maintaining decent
HD partition sizes.
