NETGEAR ReadyNAS vs Synology DS423: Which NAS Should You Choose?

The NETGEAR ReadyNAS pairs a six-bay design with a lower listed price, while the new Synology DS423 offers four 2.5/3.5-inch SATA HDD/SSD bays, dual gigabit Ethernet, and PC compatibility. This guide makes the tradeoff clear.

Last updated Aug 24, 2026

Choosing NAS storage & drives means balancing bay count, drive support, connectivity, and upfront price. NETGEAR ReadyNAS and Synology DS423 present different starting points, so the useful decision is whether a lower-priced enclosure or a newer enclosure with a more detailed hardware specification fits your plan.

Quick verdict

NETGEAR is practical when bay count and lower upfront price lead the decision. Synology fits shoppers who want defined drive formats, network interfaces, and a PC-compatible enclosure. The listed-price difference is $245, making cost a clear tie-breaker. NETGEAR's package limitation is that hard drives and cables are not included; Synology's is its diskless configuration and smaller stated bay count.

Where each product wins

NETGEAR ReadyNAS: Its title identifies a 6-bay enclosure, while RJ-45 and USB-A are named connection types. That is a concrete match for a shopper who starts with enclosure capacity and connection needs. Its lower listed price supports that decision, although the purchase is tied to the used condition and the equipment exclusions.

Synology DS423: Its case centers on a new enclosure with clearly defined drive formats and interfaces: 2.5- and 3.5-inch SATA HDD/SSD bays, dual gigabit Ethernet, and PC compatibility are named. The four-bay format is the tradeoff versus NETGEAR's six-bay title. This is a better match when enclosure specifications matter more than the lower entry price.

Product notes

NETGEAR ReadyNAS RND-6A RNDU6000-100NAS

NETGEAR ReadyNAS RND-6A RNDU6000-100NAS 6-Bay Network Attached Storage

The NETGEAR ReadyNAS RND-6A RNDU6000-100NAS suits a shopper looking for the model's bay-count emphasis and a lower entry point. At USD 129.99, it is the lower-priced choice in this comparison. Its concrete limitation is the condition and included equipment: it is marked Used, while cables and hard drives are not included. Scratches and scrapes around the body are also identified, so cosmetic appearance belongs in the decision. Select the ReadyNAS when the lower upfront price fits the plan and a used enclosure is acceptable. The absent drives and cables make it a poor match for a purchase that specifically requires those items in the package.

Synology DS423 Network Attached Storage Enclosure

Synology DS423 4-Bay Network Attached Storage Enclosure, NEW, SEALED, DISOUNTED

Synology DS423 suits shoppers drawn to a clearly specified enclosure: a Realtek RTD1619B quad-core and 2GB of DDR4 RAM are named alongside the DS423 model. Those details give a hardware-focused buyer concrete selection points beyond the enclosure name. At USD 374.99, it carries the higher listed price in this comparison. Its limitation is the diskless configuration, so drives are not part of the enclosure package. PC compatibility and the black color are also stated, which can help narrow a setup built around those requirements. Choose Synology when its enclosure details matter more than the price difference; the diskless format is a poor fit for anyone specifically seeking included drives.

Final choice by use case

  • Choose NETGEAR ReadyNAS RND-6A RNDU6000-100NAS when the lower listed price is the deciding criterion and a Used enclosure fits the plan. Its title's bay-count phrase supports a capacity-led choice.
  • Choose Synology DS423 when a specification-focused enclosure is the priority. The named Realtek RTD1619B quad-core and 2GB DDR4 RAM provide concrete selection points.
  • If priorities are tied, use the $245 price spread as the tie-breaker: choose NETGEAR for cost-led shopping, and choose Synology when its enclosure specification is the deciding factor.
