Your old 800K external drive will work on the SE/30.  On the other hand, 
I'm about to get rid of the 800K drive on my SE, because disks can get 
screwed up if you put an HD disk (formatted as an HD disk) into that 800K 
drive.  The 800K drive has no idea about HD disks, so it thinks the disk 
is not initialized.  If your software auto-formats uninitialized disks (as
I have DiskFit setup to do), the disk is zapped before you know it.

In my opinion, the moral of the story is to use 800K disks for 800K 
formats, and HD disks in HD formats.  If you have an SE/30, there's no 
good reason to format HD disks as 800K disks.
