The Capacity You Need—Now

Scalability is key. And the Seagate NAS Pro allows you to decide on the capacity that’s right for you—from a comfortably large 2TB, up to a massive 30TB. Fire it up, complete the easy installation process, and begin centralizing your data, documents and other digital assets. Back up your PCs and Macs, and start collaborating and sharing productively.

High Performance Intel Processor on Board

A 1.70GHz dual-core Intel processor, with 2GB of RAM, provides up to an impressive 200MB/s of file transfer performance. That is powerful enough to support up to 50 users, and to help give the creative pros in your group the ability to access and collaborate on large, complex files.

Working Remote, Need Files? Check the Sdrive.

The Seagate Sdrive™ is the easiest, most intuitive way to connect to your NAS Pro if you’re away from the office and need to look for or grab a file. From any desktop or laptop, access your NAS Pro 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 Seagate MyNAS as well.

Reliability Is Built In

NAS Pro uses Seagate NAS optimized drives—exclusively—in capacities up to 5TB. NAS HDDs 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.
