Choosing NAS storage & drives comes down to a practical fork: do you want more drive positions in a four-bay enclosure, or a two-bay home NAS with a focused backup setup? Condition and connectivity matter too, especially when one DS423 is used while another is new and sealed. The four choices below make that split easier: identify the right bay layout first, then weigh the home-cloud features, compatible devices, and listed price.
Quick take
- Choose a DS423 four-bay enclosure when bay count is the priority. The used and new-sealed versions share the same model while differing on condition and listed price.
- Choose the white home-cloud enclosure for private cloud backup and IP-camera monitoring in a tabletop setup.
- Choose the DS216play for new, factory-sealed condition and broad device compatibility.
- Watch the drive status: the used DS423 has no drives included, while the new-sealed DS423 and white enclosure are described as diskless.
Listed-price comparison
The four listed prices run from $329.99 to $374.99. The bars show relative price position, not capability or performance.
| Product | Listed price | Price bar |
|---|---|---|
| Synology DS423 4-Bay Enclosure, Used | USD 350.00 | |
| Synology DS423 4-Bay Enclosure, New, Sealed | USD 374.99 | |
| 2-Bay NAS Enclosure, White Home Cloud Backup | USD 346.97 | |

Decision matrix
- Layout: Both DS423 enclosures specify four bays. The white home-cloud enclosure and DS216play specify two bays.
- Condition: The first DS423 is used; the second is new and sealed; the white enclosure is new; DS216play is new and factory sealed.
- Device context: Both DS423 entries list PC compatibility. The white enclosure lists Android compatibility, while DS216play lists Android, iOS, iPhone, laptop, Mac, Memory Vault, and PC compatibility.
- Use case: The white enclosure is positioned for private cloud backup and monitoring multiple IP cameras. DS216play is described for personal or small-business storage.
- Drive status: The used DS423 has no drives included, and the new-sealed DS423 plus white enclosure are diskless.
Product notes
Synology DS423 4-Bay Network Attached Storage Enclosure, Used
At USD 350.00, the Synology DS423 4-Bay Network Attached Storage Enclosure is a used, black four-bay enclosure. That combination makes it a practical match for a buyer who specifically wants the DS423 model and four drive positions without moving to the new-sealed version. The trade-off is clear: the enclosure has no drives included, and its used condition may bring small imperfections such as scratches. Choose it when the four-bay DS423 layout matters more than new condition; skip it when visible wear would bother you or when you want a package that does not require adding drives.
Synology DS423 4-Bay Network Attached Storage Enclosure, New, Sealed
The Synology DS423 4-Bay Network Attached Storage Enclosure, New, Sealed is the new, sealed four-bay path at USD 374.99. Its black enclosure is PC-compatible and uses Ethernet; it also includes two Gigabit Ethernet ports and 2GB of DDR4 RAM. That combination suits a buyer who wants the DS423 format with new condition rather than a used enclosure. The limitation is that it is diskless, so drives still need to be added, and its listed price is the highest of the four. Choose it when new, sealed condition and four bays are central; the used DS423 is the closer match if condition matters less and the lower listed price does.
2-Bay Network Attached Storage NAS Enclosure, White Home Cloud Backup
The 2-Bay Network Attached Storage NAS Enclosure, White Home Cloud Backup is a new, white, diskless tabletop enclosure priced at USD 346.97. Its clearest use-case match is home cloud backup: it is presented for storing files, running backups, and monitoring a property with multiple IP cameras. Android compatibility, a plastic and tempered-glass build, and quiet, low-power operation add context for a home setup. The limitation is that drives must be added because the enclosure is diskless. Choose it for the private-cloud and monitoring focus; select a DS423 when the four-bay layout matters more.
Synology DiskStation DS216play 2 Bay NAS, Factory Sealed
The Synology DiskStation DS216play 2 Bay NAS, Factory Sealed is the lowest-priced of the four at USD 329.99 and is marked new with a factory-sealed presentation. Its black enclosure uses Ethernet and lists compatibility with Android, iOS, iPhone, laptop, Mac, Memory Vault, and PC. That broad device list makes it a clear fit for mixed-device households or small offices. The limitation is the two-bay layout, so it is not the four-bay choice represented by either DS423 enclosure. Choose it for sealed, two-bay network storage and broad device compatibility; choose the DS423 models when four bays are the deciding requirement.
Final recommendation by use case
- For a four-bay setup: Choose the Synology DS423 4-Bay Network Attached Storage Enclosure when the DS423 model and four-bay layout are the main priorities.
- For new, sealed DS423 storage: Choose the Synology DS423 4-Bay Network Attached Storage Enclosure, New, Sealed, accepting its diskless configuration and highest listed price.
- For private-cloud backup and camera monitoring: Choose the 2-Bay Network Attached Storage NAS Enclosure, White Home Cloud Backup.
- For broad device compatibility: Choose the Synology DiskStation DS216play 2 Bay NAS, Factory Sealed, whose compatibility list covers Android, iOS, Mac, PC, and more.
