The interfaces on the Amiga 570 and 590 are clearly unique. Unlike the other Amiga disk drives, which reside on the Amigas "Floppy" bus, these drives actually plug into the Amiga 500s expansion bus (where memory expansion, CPU upgrades, and other peripherals would also go).
The A570 was released in 1991 soon after the CDTV. Its purpose was actually to allow an Amiga 500 to emulate the CDTV unit by providing not only the necessary proprietary interface CD-ROM drive, but by also providing the CDTV ROM chips as well.
The A590 includes an RDB and SCSIDirect compatible SCSI adaptor along with 2 megabytes of RAM expansion. The A590 also includes an XTIDE interface, which is the 8-bit version of the modern ATA IDE. Reportedly, some 590s were actually shipped with XTIDE drives, though most included SCSI units.
