IronWolf Pro 6 TB NAS Drive
This 3.5-inch internal hard drive delivers 6 TB of storage on a SATA 6.0 Gb/s interface. It spins at 7 200 RPM with a 256 MB cache and is engineered for multi-bay NAS enclosures. The AgileArray firmware adds dual-plane balancing and RAID optimisation for 24 × 7 operation.
Before ordering check
Verify that your NAS or server has a free 3.5-inch drive bay and a SATA data plus power connection. Confirm the chassis can accept a drive up to 26.11 mm high, 101.85 mm wide and 146.99 mm long. Ensure the system supports SATA 6.0 Gb/s speeds for full throughput.
Build integration
The bare drive weighs roughly 1.72 lb and mounts in standard 3.5-inch trays using four side screws. It draws power from a standard SATA power connector and requires no extra cabling. Rotational-vibration sensors and a 300 TB per year workload rating suit always-on arrays. IronWolf Health Management and a two-year Rescue Data Recovery plan add monitoring and recovery support.

Questions about this item
Does the bare-drive package include any cables or mounting brackets?
The drive ships as a bare unit only; SATA data and power cables plus any 3.5" mounting hardware must be sourced separately.
When should I choose the 6TB 7200 RPM model over a lower-capacity IronWolf Pro?
Pick this 6TB model when you need the 300TB per year workload rating and 1.2M hour MTBF in a multi-bay NAS that demands 24x7 operation.
What does the 256MB cache and 7200 RPM spindle speed deliver in an actual NAS array?
The 256MB buffer and 7200 RPM rotation combine with AgileArray dual-plane balancing and RV sensors to sustain high-throughput RAID workloads with low 4.16ms average latency.
