Choosing NAS storage & drives means balancing a lower upfront cost against a more complete backup and sharing setup. The Seagate BlackArmor NAS 400 series keeps the decision focused on a NAS device and centralized storage, while the LinkStation 210 brings a broader set of backup, access, and file-sharing features. The better fit depends on whether simplicity or built-in management tools matter more.
Quick verdict
Choose the Seagate BlackArmor NAS 400 series if the priority is a lower listed price and a straightforward network storage device, and its Used condition and External Drive type suit your plans. Choose the LinkStation 210 if you want a new NAS setup with an included HDD, RAID, scheduled backups, and secure sharing features. It asks for a substantially higher outlay, but its feature list is much more focused on managing files across multiple devices.

Product notes
Seagate BlackArmor NAS 400 series

At $39.00, the Seagate BlackArmor NAS 400 series is the practical choice when keeping the purchase cost low matters most. Its title identifies it as a Network Attached Storage device, and its description presents centralized storage and management for a network. That makes it relevant for someone who wants a NAS-labeled device without the broader backup toolkit associated with the LinkStation 210. The limitation is concrete: it is listed as Used, and its type is External Drive. Those details make the Seagate less suited to someone specifically seeking a new setup or the scheduled-backup, encryption, and access-control tools named for the LinkStation 210.
LinkStation 210

The LinkStation 210 makes the stronger feature-led case for a home setup that needs centralized backup and sharing. Its title calls out 2TB Network Attached Storage, while the description adds RAID, an included HDD, scheduled backups, SSL encryption, individual access restrictions, and secure file sharing. Desktop and laptop support, along with Windows and macOS compatibility, gives the setup a clear cross-device use case. The tradeoff is its $268.99 listed price and HDD-supported design. Shoppers who want the lower-priced Seagate or prefer an External Drive format may not need the LinkStation's larger collection of backup and sharing functions.
Final choice by use case
- Lowest purchase price: Pick the Seagate BlackArmor NAS 400 series. Its USD 39.00 listing and NAS device title make the decision straightforward for cost-first shoppers.
- New setup: Pick the LinkStation 210, which is listed as New and combines an included HDD with network storage features.
- Scheduled backups and controlled sharing: Pick the LinkStation 210 for its scheduled backups, SSL encryption, individual access restrictions, and secure file sharing.
- Simple external-drive route: Pick the Seagate if its External Drive type matches the way you want to use network storage.
The Seagate is the sharper fit for a lower-cost, simpler NAS purchase. The LinkStation 210 is the more appropriate choice when RAID, backup automation, and sharing controls justify its higher listed price.
