Ideally, neither: 80-track double density. An RX50 is only
single-sided (80 tracks, 10 sectors of 512 bytes per track), but
obviously a double-sided drive will do, and that includes a "1.2M"
drive if it's capable of doing DD as well as HD.

"disc" is from the Greek "discus", and is (or was, until recently) the
more commonly accepted English spelling; "disk" is an Americanism which
has spread to the UK. Acorn always used "disc" as well.
