Choosing NAS storage & drives means balancing room for storage against the features you will actually use. The Synology DS423 has a four-bay layout and supports HDDs, while the 2-Bay Network Attached Storage NAS Enclosure is a diskless two-bay home cloud option with monitoring features. Their listed prices are close, so the real decision is whether you want more bays or a newer, home-focused feature set.
Quick verdict
Choose the Synology DS423 if the listed four-bay design and HDD support are the deciding factors. Choose the 2-Bay Network Attached Storage NAS Enclosure if you prefer a new white enclosure with private-cloud access, home monitoring, and quiet, low-power operation. The listed price difference is just $3.03, so the choice is mainly about configuration rather than a meaningful price gap.

Where each one wins
Synology DS423: more bay capacity
The DS423 is the clearer fit for a home NAS plan centered on a four-bay enclosure. Its listed HDD support and Ethernet interface also give the setup a straightforward storage-server profile for PC users. That extra bay count is the meaningful distinction here, especially if your priority is having a larger enclosure layout rather than a compact two-bay starting point.
2-Bay NAS Enclosure: home-cloud features
The 2-Bay enclosure stands out for its explicitly described home-use features: private-cloud file access from desktop, laptop, Mac, PC, or mobile devices; 24/7 home monitoring; and support for multiple IP cameras for remote viewing. Its white finish, tabletop form factor, and quiet, low-power operation also make its intended role easy to understand. The $3.03 lower listed price adds a small tie-breaker, but its two-bay diskless design remains the central trade-off.
Product notes
Synology DS423 4-Bay Network Attached Storage Enclosure

The Synology DS423 makes the most sense when four bays are more important than a home-monitoring feature set. Its listed HDD support, Ethernet interface, black color, and PC compatibility point toward a conventional network storage setup, while the DS423 model name gives the enclosure a specific identity for shoppers comparing NAS hardware. The limitation is that it is listed as used, and the description says to expect small imperfections such as scratches. It also includes no drives, so the enclosure is not presented as a ready-to-use storage bundle. For someone comfortable with a used enclosure and planning around a four-bay layout, those are clear considerations rather than reasons to dismiss it outright.
2-Bay Network Attached Storage NAS Enclosure Diskless White Home Cloud Backup

This enclosure is a strong match for a home user who wants the NAS to cover more than file storage. The description specifically calls out private-cloud access, backup use, 24/7 home monitoring, multiple IP-camera viewing, and quiet, low-power operation. Its new condition, white finish, tabletop form factor, and Android compatibility further support that home-oriented brief. The main limitation is the listed two-bay diskless configuration: it does not offer the four-bay layout of the Synology DS423, and drives are not included. That makes the enclosure appealing for a focused home setup, but less suitable when the deciding requirement is simply having four bays in one unit.
Final choice by use case
- Choose the Synology DS423 for a four-bay NAS enclosure with listed HDD support and an Ethernet interface, provided a used unit and no included drives fit your plan.
- Choose the 2-Bay NAS Enclosure for private-cloud access, backup use, home monitoring, and quiet, low-power operation in a new diskless enclosure.
- If the decision is based only on price, the $3.03 spread is too small to outweigh the storage-layout difference. Pick the bay count and feature set that matches how you expect to use your home NAS.
