Manufacturer description
The Seagate IronWolf Pro ST4000NE001 is a 4 TB 3.5-inch internal hard drive built for multi-bay NAS enclosures that never power down.

Seagate positions the IronWolf Pro line for creative professionals and small-to-medium business NAS workloads, with AgileArray firmware handling dual-plane balancing, RAID optimization, and power management in multi-drive arrays where vibration and command queuing matter more than raw single-drive speed.

Frequently Asked Questions
Is the Seagate IronWolf Pro ST4000NE001 rated for 24/7 NAS use?
Yes. Seagate designs the IronWolf Pro line for 24x7 operation in multi-drive NAS enclosures, which is what separates it from desktop-class drives used in the same bays.
Will this drive fit my NAS enclosure?
It is a 3.5-inch internal drive using a SATA 6 Gb/s (SATA/600) connection, so it fits standard 3.5-inch bays in most desktop NAS, DAS, and tower server chassis. It will not fit 2.5-inch-only enclosures.
What does AgileArray actually do?
Per Seagate, AgileArray firmware enables dual-plane balancing and RAID optimization for multi-bay environments, plus power management tuned for arrays rather than single-drive desktops.
What warranty and data-recovery coverage comes with it?
Warranty and any included data-recovery service terms are not listed in this product data. Check the current Amazon listing and Seagate's product page for the terms that apply to your purchase.
