Built for multi-bay NAS

The IronWolf 12TB 3.5-inch drive uses a SATA 6.0Gb/s interface and spins at 7200 RPM with 256MB cache. CMR recording technology and AgileArray firmware enable dual-plane balancing and RAID optimisation across multi-bay enclosures. Rotational vibration sensors sustain performance when several drives operate together. Designed for 24x7 operation in network-attached storage systems.

Mechanical readiness for rack duty

A 26.11 mm height, 101.85 mm width and 146.99 mm length fit standard 3.5-inch drive trays and hot-swap carriers. The SATA data and power connectors face the rear for clean cabling in dense chassis. AgileArray power management reduces spin-up current peaks, easing the load on shared power supplies during simultaneous drive starts. RV sensors compensate for chassis-borne vibration without extra mounting hardware.

Step up from lighter NAS drives

The 180 TB per year workload rating and 1M-hour MTBF exceed desktop-class and entry-level NAS drives, making the jump worthwhile when arrays run continuous backup, media streaming or virtualisation workloads. IronWolf Health Management adds preventive monitoring, intervention and recovery tools that basic drives lack. Not suited for single-bay appliances that cannot use RV sensing or for systems needing SSD latency.

商品問答

What does the SATA 6.0Gb/s interface mean for actual transfer speeds?

The SATA 6.0Gb/s link sets a theoretical ceiling of 6 Gb/s; sustained reads and writes from the 7200 RPM platters typically run below that limit, so the drive will not saturate the bus in everyday NAS workloads.

What physical space does the 3.5" drive need in a NAS bay?

The unit measures 146.99 mm long, 101.85 mm wide and 26.11 mm high, so the bay must accommodate those maximum dimensions plus clearance for power and data cables.

How is the drive installed in a multi-bay NAS, and what step is often missed?

Mount the drive using the 3.5" screw holes, connect SATA data and power, then enable IronWolf Health Management in the NAS firmware so the drive can report its health and rotational-vibration data to the array manager.
