I'm possitive this a rebadged Sanyo, and not Plextor, well, because I own one
No worries, I was here to clear it up.
It took me forever to figure out who made it myself, till I checked out

Iomega only sells the IDE version. Sanyo made both a SCSI and IDE version.
Also, Sanyo released a new Firmware yesterday, so I'd imagine Iomega will release their version of it soon
