NAS-optimised 2 TB drive

The Seagate IronWolf Pro ST2000NE0025 is a 3.5-inch internal hard drive built for multi-bay NAS enclosures. It spins at 7200 RPM with a 128 MB cache and connects over a SATA 6.0 Gb/s interface. Average latency is 4.16 ms and the physical height is 26.11 mm.

AgileArray and health tools

AgileArray firmware provides dual-plane balancing and RAID optimisation across multiple bays alongside advanced power management. Rotational vibration sensors sustain performance in dense chassis. IronWolf Health Management focuses on prevention, intervention and recovery. A bundled Rescue Data Recovery plan offers a 90 % in-house success rate for mechanical, accidental or natural-disaster events.

Suits multi-bay NAS builds

This drive suits users who need NAS-class reliability, rotational-vibration tolerance and integrated health monitoring in a 2 TB package. Builders requiring higher single-drive capacities, faster SSD speeds or non-SATA interfaces should look at other options.
