NAS-Ready 6 TB CMR Drive

The Seagate IronWolf Pro ST6000NE0023 is a 6 TB 3.5" internal hard drive built for multi-bay NAS enclosures. It spins at 7200 RPM with a 256 MB cache and uses Conventional Magnetic Recording for consistent write performance. The SATA 6.0 Gb/s interface fits standard drive bays and hot-swap trays in home or small-business servers. It is designed for always-on workloads in RAID arrays.

AgileArray Firmware and Physical Fit

AgileArray firmware adds dual-plane balancing and RAID optimisation to reduce vibration in crowded chassis. Advanced power management lowers heat and acoustic output during idle periods. The bare drive measures 26.11 mm high, 101.85 mm wide and 146.99 mm long, weighing approximately 1.55 lb. Hot-plug support allows drive replacement without shutting down the NAS.

Verify Bay Count and RAID Plan

Confirm your NAS has a free 3.5" SATA bay and that the controller supports the desired RAID level for a 6 TB volume. Check that the power supply can deliver adequate current for an additional 7200 RPM spindle. Buyers needing hardware encryption or a five-year data-recovery service should look at other IronWolf Pro SKUs. Ensure your backup strategy covers the full capacity before deploying.

Questions about this item

What does the SATA 6.0Gb/s interface cap in practice?

The SATA 6.0Gb/s interface caps the maximum theoretical transfer rate at 6.0Gb/s; real-world sequential speeds are limited by the 7200 RPM mechanical design and 256MB cache.

What physical space does the 3.5" drive need to fit or mount?

The drive measures 146.99mm long, 101.85mm wide and 26.11mm high, matching standard 3.5" drive bays with a 1.55 lb weight.

How is the drive installed and what step do people get wrong?

Mount the 3.5" drive in a bay, connect the SATA data and power cables, then enable hot-plug in the BIOS or RAID controller so the drive is recognised on insertion.
