24 TB CMR NAS drive

This 24 TB hard drive uses conventional magnetic recording and a 7200 RPM spindle to serve multi-bay NAS enclosures. A 512 MB cache and AgileArray firmware with dual-plane balancing and TLER keep RAID arrays responsive. The SATA 6.0 Gb/s interface fits standard 3.5 inch drive bays in commercial and enterprise storage servers.

Sustained 24x7 workload rating

Rated for 550 TB per year, the drive is built for continuous operation rather than burst transfers. Rotational vibration sensors and time-limited error recovery maintain consistent throughput across all bays during heavy multi-user loads. The 2.5 million hour MTBF figure reflects design targets for always-on environments.

Check bay count and controller

Verify that your NAS chassis has enough 3.5 inch bays and that the RAID controller or HBA supports SATA 6.0 Gb/s links. Confirm the system can supply adequate cooling for a 26.11 mm high drive running at 7200 RPM. Ensure your backup strategy accounts for the 24 TB capacity before deploying in a production array.

Questions about this item

How much noise and heat does the 7200 RPM mechanism generate during 24x7 operation?

The 7200 RPM CMR design is built for continuous 24x7 use with a 550 TB per year workload rating and 2.5 million hours MTBF, while AgileArray dual-plane balancing and RV sensors limit vibration and heat in multi-bay NAS.

What host interface and physical bay does the 3.5 inch SATA 6.0 Gb/s drive require?

It needs a standard 3.5 inch drive bay with a SATA 6.0 Gb/s data port and a SATA power connector; the drive measures 146.99 mm long, 101.85 mm wide and 26.11 mm high.

Will the AgileArray firmware and TLER work with an older RAID controller that expects enterprise drives?

Yes, AgileArray includes time-limited error recovery and rotational vibration sensors tuned for multi-bay RAID, so the drive responds correctly to legacy controllers expecting enterprise-class behaviour.
