[comp.sys.mac] Do old Mac SE external hard drives still work with SE/30's?

I was wondering if someone can answer this question.  Part of the speed of
the new SE/30s to access info on the hard drive (HD) deals with the speed of
the processor and RAM chips I assume, BUT doesn't the interleave ratio of the
HD also have something to do with the speed of an SE30 that makes it look so
fast?  If this is so, and I wanted to upgrade my SE to an SE30 motherboard,
would I:

1) really see a speed improvement on my external Peripheral Land PL30Mb HD?

2) have to reformat the HD to make it run faster with the new 030 motherboard?

3) have to buy newer, faster SIMMs also (another expense for the 030 upgrade)?

4) have to buy a new HD for speed compatibility (another expense)?

This seems like a lot of potential hidden costs and headaches to upgrade a
MAC SE (dual floppy) to an SE30.  Will ALL this be necessary for such an
upgrade?

Also, IS IT EVEN POSSIBLE for a dual floppy MAC SE to accomodate the 030
motherboard upgrade?  Or will I have to sacrifice one of my floppy drives?

Thanks for any answers you can provide.
