It turns out the Priam 806 8-inch SCSI HDD circa 1984 is likely the first HDD to have a native SCSI interface. It shipped a few months before the Xebec Owl which is likely second. AFAIK all earlier units had a bridge controller to a more conventional interface. If anyone has any different info as to dates and models I would appreciate it. Does anyone know where a Priam 806 might be, or have any documentation? The former probably belongs in a museum and the latter on Bitsavers. I will help facilitate either.
