Choosing nas storage & drives often means deciding whether you need a simple network backup endpoint or a more structured enclosure for a planned drive setup. The D-Link DNR-326 and Synology DS423 point to those different priorities: one emphasizes a basic desktop NAS role, while the other presents a more fully specified enclosure. The useful shortcut is to separate the price-led decision from the configuration-led one.
Quick verdict
Pick D-Link when the goal is basic network backup at the lower listed price. Pick Synology DS423 when you want a planned enclosure with a more explicit drive layout. The deciding line is the cost gap versus the defined storage structure.

Where each product wins
D-Link DNR-326 wins on upfront price

The absolute listed-price spread is $324.99, making the desktop unit the price-led choice for basic network backup or file access. Its stated 12V adapter requirement is a concrete setup consideration. Ethernet is listed for both products, so that shared interface does not separate them.
Synology DS423 wins on defined configuration
Synology specifies 4 bays, a 2.5 and 3.5 in form factor, two Gigabit Ethernet ports, and 2GB of DDR4 RAM. That configuration gives shoppers more specific parameters for a planned storage layout. The enclosure is diskless, so the purchase is centered on the housing rather than included drive capacity. Choose it when that enclosure structure matches your planned setup.
Product notes
D-Link DNR-326
The D-Link DNR-326 suits a shopper who wants a straightforward network storage role for home or office backup. As a Network Attached Storage desktop unit, it fits a basic file-access plan and the product description positions it for backing up and storing data across a network. The limitation is explicit: it is gently used, sold as is, and requires a 12V adapter. Choose the DNR-326 when its Ethernet interface and backup purpose match the job, and when the used condition and adapter requirement are acceptable.
Synology DS423

The Synology DS423 suits a shopper who wants a clearly identified enclosure for a planned storage setup. As a Network Attached Storage Enclosure, it has a specific role distinct from a standalone drive. The limitation is equally concrete: it is diskless, so the drives and resulting capacity are not part of the purchase. That makes the DS423 a starting point for a storage build rather than a ready-filled capacity package. Choose it when the enclosure itself is what you need to add to a drive plan, and when purchasing separate drives fits your setup.
Final choice by use case
- For the lower-cost home or office backup path: choose the D-Link DNR-326 at $50.00. Its basic desktop NAS role suits a straightforward file-access setup.
- For a planned enclosure build: choose the Synology DS423 at $374.99. Its new, diskless enclosure format and defined hardware scope make sense when the enclosure itself is the priority.
- Bottom line: the $324.99 spread makes D-Link the price-led choice, while Synology is the configuration-led choice. Match the enclosure scope to the way you plan to store and access files.
