The 840AV supports interleaved memory access, which contributed to its performance advantage over other Quadra models.

=== Storage Systems ===

The Quadra 840AV shipped with internal SCSI hard drives in three configurations:
* 230 MB
* 500 MB
* 1 GB

A 1.44 MB 3.5" floppy drive is standard. An internal 2X CD-ROM drive was optional on entry-level configurations and standard on higher-end models. One 5.25" expansion bay is available (or two if no CD-ROM is installed).
