Frequently Asked Questions

What is HelioSeal technology?

HelioSeal is WD's hermetically sealed helium-filled drive design. Helium is less dense than air, reducing internal turbulence and enabling more platters in the same 3.5-inch form factor — delivering higher capacity with lower power consumption and heat generation.

What is the difference between 0F59373 and WUH722624AL5204?

Both are Ultrastar DC HC590 24TB SATA drives. The 0F59373 is an alternate OEM part number while WUH722624AL5204 is the standard OEM part number for the same drive — typically used by different system integrators or storage vendors.

The WD Ultrastar DC HC590 0F59373 delivers 24TB of enterprise SATA storage with HelioSeal, 512MB cache, 512e/SE, and 2.5M hour MTBF — an ultra-high-capacity, reliable SATA HDD for hyperscale, cloud, and enterprise data center bulk storage deployments.
