This page lists the internals of the D-Link DNS-323. There is another page which shows the status of support in Debian for these components.
There are currently two revisions of the D-Link DNS-323, revision A1 and B1. Revision A1 uses a Marvell 88F5181 CPU along with a separate SATA chip. Revision B1, on the other hand, uses a Marvell 88F5182 CPU which integrates SATA into the SoC itself. The DNS-323 revision B1 is also sold by Conceptronic as the CH3SNAS.
