Capacity and purpose

This 24TB enterprise hard drive uses a 3.5 inch form factor and a SATA 6.0Gb/s interface. It is intended for hyperscale storage arrays, cloud infrastructure and massive scale-out data centres that need maximum density per rack. Buyers who need a smaller footprint or a different interface will not be served by this model.

Sustained workload behaviour

The drive spins at 7200 RPM with a 512MB cache and is rated for 550TB per year of enterprise nearline workloads. A 2.5 million hour MTBF and helium-filled design support consistent response rates during continuous operation. It is not aimed at burst-oriented desktop tasks or low-duty-cycle environments.

Build and connectivity

The bare drive measures 147.00mm long, 101.85mm wide and 26.10mm high, fitting standard 3.5 inch bays with a SATA data and power connector. Shock protection and a data protection system are integrated. No mounting rails, cables or adapter brackets are included.

Questions about this item

How much heat and noise does the 24TB 7200 RPM drive produce when running continuously in a server rack?

The PowerBalance feature optimises watts per terabyte, and the helium-filled design reduces turbulence, keeping heat and acoustic output low for 24/7 operation in dense enclosures.

What host interface and cabling do I need to connect this SATA 6.0Gb/s 3.5" drive?

A free SATA 6.0Gb/s port on the motherboard or HBA, a standard SATA data cable, and a SATA power connector from the PSU are required; the drive uses the 3.5" form factor.

Will the 512MB cache and 7200 RPM speed work well alongside older 4TB SATA drives in the same array?

Yes, the SATA 6.0Gb/s interface is backward compatible, so the drive will negotiate the highest common speed and operate reliably in mixed-capacity arrays.
