The Seagate 4TB STCU4000100 4-Bay NAS Server offers four bays and two 2TB Seagate NAS drives capable of delivering reliable performance 24 hours a day, 7 days a week. The preconfigured network storage solution allows users to collaborate, share and access files even when on the go. The server is great for both home use and business use, providing better hardware performance and protection than standard hard drives.

The NAS server features SimplyRAID technology that's built into the NAS OS 4 software. This technology guides you in choosing between JBOD, RAID 0, 1, 5, 6, and 10, which can offer performance, capacity, redundancy, or a combination of performance and redundancy. Once configured, connect the NAS server to your network via the two Gigabit LAN ports or to your Windows, Mac, Linux PC via USB 3.0. By offering two LANs with failover and link aggregation with a convenient hot swappable spare support, ensures continual service in the event that one of the drives require replacement or a LAN fails unexpectedly.

For accessing files on the NAS when on the go, Seagate offers Sdrive for PC, Mac, Android, and Apple OS devices. The Sdrive app for mobile devices offers enhanced security by encrypting the files before they leave the NAS and requires user credentials to decrypt and access the files. Within the App Manager in NAS OS 4, you can install apps that turn the NAS into a recording solution for IP cameras or an anti-virus app that can scan files and identify potential threats before it's too late. It also features NAS-to NAS backup, which allows IT administrators to back up shares to other NAS devices on the network or to a remote location over the Internet. By backing up over the Internet to a second Seagate NAS server provides offsite protection while retaining ownership of your data. Another feature is built-in iSCSI support, which offers performance and provides additional storage for servers and workstations on the network that supports IP SAN and NAS applications. Along with the Seagate 4-Bay server are a power cable and Ethernet cable.


Seagate NAS OS 4
Configure and set up multiple devices with the interface. From your laptop or desktop workstation, and equally from your tablet and smartphone, Seagate NAS OS 4 incorporates software features to keep your projects available, secure, and running smoothly.

Connect up to 25 users to data that is centralized and secure without the need for an IT department.

RAID Protection
Seagate offers SimplyRAID technology, which automatically manages installed drives to give you the optimal blend of capacity and redundancy. Choose between protection in case of one or two simultaneous drive failures, and SimplyRAID will figure out the rest. Seagate NAS servers with pre-installed drives have SimplyRAID configured at the factory to help get you up and running faster.

The Seagate Sdrive is an intuitive way to connect to your NAS if you're away from the office and need to look for or grab a file. From any desktop or laptop, access your NAS by clicking the Sdrive icon (from Computer or Finder). Go ahead and drag-and-drop files, or search for that particular file and open it directly with its native application. From your smartphone, you can securely and easily access your files from the Sdrive as well.

These pre-installed NAS hard drives are designed specifically for NAS applications running 24×7 and are much more reliable than standard desktop hard drives. With improved vibration tolerance and advanced management capabilities, the industry-leading NAS HDDs on board can support several optimum power and performance profiles so you can strike the right balance.

Seagate Antivirus
With the Daily Updates engine, Seagate Antivirus will protect your data and systems from the most volatile threats. Manual Scan lets you add large amounts of content or schedule a scan when your NAS isn't in use; the choice is yours. Event Reporting allows you to easily sift through your scans with filtering capabilities.

  • Daily Updates make sure your data is safe from the most recent threats
  • Stay informed with email notifications
  • Whitelist specific files and folders that you don't want scanned
