The DNS-323 represents D-Link’s next stab at network storage, and this time it has gone for SATA drives instead. The appliance is one of the smallest we’ve seen and its compact, matt-black aluminium chassis is designed to accept two SATA drives of your choosing. The entire installation process is completely tool-free - simply push the front cover upwards to release it and then slot in a couple of drives. The rear panel has a lever behind each bay to aid drive removal.
