System Overview

Enclosures shipped with hard drives feature Seagate's NAS HDD. For more information, go to NAS HDD.

New or replacement hard drives must meet the following requirements:

  • SATA I or higher
  • 3.0Gb/s or higher
  • Spin up to 7200 RPM

In case of disk failure or, the need to expand storage capacity, each individual hard drive is hot-swappable and field replaceable. When adding hard drives to the enclosure, consider using Seagate NAS HDD.

Seagate NAS OS

The 4-bay Rackmount NAS is managed by Seagate NAS OS. Written to all drives within the enclosure, NAS OS helps you to create volumes with RAID protection. Direct attached storage (DAS) can be connected to the enclosure's external ports for NAS backup. However, it is not possible to expand volumes using DAS.
