Choosing NAS storage & drives puts two used four-bay enclosures in a practical trade-off: do you prioritize a more specifically described setup, or a lower entry point? The Synology DS423 identifies HDD support, Ethernet, and PC compatibility, while the Qnap TS-431P2 frames itself as a NAS and Personal Cloud. Both can serve as starting points for network-attached storage, but the included hardware changes the buying decision.
Quick verdict
The Synology DS423 is the better fit when setup-specific hardware details should drive the decision. The Qnap TS-431P2 suits a shopper focused on a straightforward NAS enclosure purchase. The central question is whether the more detailed hardware profile or the simpler entry point better matches the way you plan to build storage.

Where each product wins
- Synology DS423: It wins for a setup where HDD support, an Ethernet interface, and PC compatibility are the deciding attributes; all three are explicitly named for this enclosure.
- Qnap TS-431P2: It wins for a shopper who wants four caddies included, a concrete package detail that can matter when assembling an enclosure.
Product notes
Synology DS423
The Synology DS423 suits a shopper who specifically wants a black enclosure identified by the DS423 model. That is a concrete reason to choose it without assuming extra software or storage features. The limitation is the starting package: the description says no drives are included. It is also a used unit, with small imperfections such as scratches called out as possible. The purchase is therefore an enclosure to configure rather than a complete drive-filled setup. Choose Synology when a black DS423 enclosure suits the plan; the no-drives package and used condition are the main limitations.
Qnap TS-431P2
The Qnap TS-431P2 fits shoppers drawn to the *Personal Cloud* wording in its title and a straightforward NAS enclosure purchase. That is a concrete reason to choose it without assuming extra software or services. Its limitation is the stated package: no power adapter and no drives are included. The unit is also used, so the purchase is a component to configure rather than a complete storage setup. Choose Qnap when the Personal Cloud framing fits the intended use and adding the adapter and drives is acceptable. A shopper who specifically wants the black DS423 enclosure should instead choose Synology DS423.
Final choice by use case
For a home NAS setup centered on HDD support, Ethernet, and PC compatibility, choose Synology DS423; those attributes are explicitly listed and give the decision a clear hardware basis. For the lower-priced use case, choose Qnap TS-431P2. Its $169.95 price is $180.05 below Synology's $350.00, so Qnap makes sense when initial cost matters more than configuring the stated package. Synology is the better-aligned choice when those named connection and drive-support details matter more than minimizing initial spend.
