HDD, WESTERN DIGITAL ULTRASTAR, Ultrastar DC HC580

24TB data center HDD with OptiNAND technology
The relentless growth of data means organizations must find ways to efficiently store ever more data. The Ultrastar DC HC580 24TB1 HDD with improved OptiNAND technology is the next step in high-capacity hard drives, allowing data centers to maximize their storage, especially in footprint- and powerconstrained environments.

Keep up with exponential data growth
The 24TB1 Ultrastar DC HC580 HDD with OptiNAND technology’s capacity-enabling features provides more efficient storage on a 10-disk CMR drive, enabling you to store more in the same footprint

Innovative technologies for higher capacities
Improved OptiNAND technology, energy-assisted magnetic recording (EAMR), triplestage actuator (TSA), and HelioSeal enable high capacity with low power

Performance and protection
ArmorCache is a feature enabled by OptiNAND that offers higher performance in write cache disabled mode and provides enterprise power loss protection in write cache enabled mode

Designed for data center workloads
The Ultrastar DC HC580 is performance-optimized to handle heavy application workloads of up to 550TB2 per year.

Built with reliability in mind
This robust drive delivers dependability in intense data center environments with up to 2.5M hours MTBF3 (projected).
