More likely SCSI (single 50pin cable) or EDSI (two
cables like MFM).
MFM drives topped out at 160mb or so, EDSI went to at least 400mb maybe
higher.
ESDI, and I know they can handle higher capacity disks (though I can't
speak to the actual limit) as I have several ESDI disks which are
770mb unformatted (about 668mb formatted). A couple of them are the
Hitachi DK515-78. I also have some Maxtor drives, but I don't remember
their designation.
