I’m developing a small library and trying to outweigh the pros and cons of using Vector vs. Array.

So far, I can only think of a few things to think of:

**Vector only works for FP10, while Array works for both 9 and 10.**

**Vector is typed** (which is a wonderful, fabulous thing), but if I’m only using the Array as a private variable, so I have full control over what goes in and comes out of it, this factor may not play as great a part anymore, but definitely great protection.

I believe I heard somewhere that Vector is a lot faster than Array, yet in a quick inconclusive speed test I did a while back, it didn’t seem to make any real difference at all.

**Is Vector really faster than Array? If so, is it faster in all aspects, or only faster in certain situations** just as uint is only faster than Number when using byteshifting?
