Adam,
You can have up to 4 primary partitions. If data recovery ever became
necessary, primary partitions are much more likely to be successful in
recovery than logical partitions (which are actually partition(s) within a
(primary) partition).
Right on the fixed size. Low and high values the same make it "fixed."
