Built for multi-bay NAS
The Seagate IronWolf ST6000VN0041 is a 6TB 3.5-inch internal hard drive spinning at 7200 RPM with a 128MB cache and a SATA 6.0Gb/s interface. It is engineered for always-on operation in network-attached storage enclosures and carries a workload rating of 180TB per year. AgileArray technology provides dual-plane balancing and RAID optimisation across multiple drive bays.
Check your NAS bay and controller
Verify that your enclosure accepts a 3.5-inch drive measuring up to 146.99mm long, 101.60mm wide and 26.11mm high. Confirm the system provides a free SATA 6.0Gb/s port and sufficient power for a 7200 RPM mechanical drive. Ensure the NAS firmware supports IronWolf Health Management if you want active drive monitoring and alerts. The drive ships as a bare unit without cables or mounting hardware.
Suits home and small-business NAS
This drive fits users building or expanding a multi-bay NAS who need 6TB of capacity with 24x7 reliability and rotational-vibration tolerance. It is not intended for desktop boot duty, external USB enclosures or single-drive archival storage where NAS-specific firmware and RV sensors add no value. Buyers needing capacities beyond 6TB should consider larger models in the same series.

Questions about this item
Does the Seagate IronWolf ST6000VN0041 come with cables or mounting screws, or must I buy them separately?
This drive is supplied as a bare 3.5" unit without SATA data cables, power cables or mounting screws. You will need to provide those separately for installation in your NAS enclosure.
Should I choose the 6TB IronWolf or a different capacity from the 1/2/3/4/6/8/10/12/14TB range for my NAS?
Pick the capacity that matches your usable storage target and RAID layout. The 6TB model gives you 6TB raw space and shares the same 7200 RPM, 128MB cache and 180TB/year workload rating as the other IronWolf capacities.
What does the 180TB/year workload rate mean for daily use in a multi-bay NAS?
It means the drive is rated to handle up to 180 terabytes of data written or read per year — typical for always-on, multi-user NAS workloads — without exceeding its design limits.
