With an impressive capacity of 20 TB and a robust 12 Gb/s SAS interface, this 3.5-inch hard disk drive provides the ideal foundation for servers, high-end NAS systems with more than 8 bays and professional workstations. Its CMR (Conventional Magnetic Recording) technology ensures maximum reliability and consistent performance, even under extreme workloads. Benefit from a storage solution designed for continuous operation that securely manages your critical data.

Maximum reliability and efficiency in continuous operation

The Ultrastar DC HC560 series is characterised by its outstanding durability and efficiency. Thanks to the innovative HelioSeal technology, in which the hard disk is filled with helium, friction and vibrations are minimised, resulting in lower power consumption and a cooler operating temperature. Rotational Vibration Safeguard (RVS) sensors compensate for vibrations in multi-bay environments, thereby guaranteeing stable performance in large storage arrays. With a workload rate of up to 550 TB per year and an MTBF of 2.5 million hours, this HDD is the first choice for business-critical applications requiring 24/7 availability.

Optimised for data integrity and scalability

The WD Ultrastar DC HC560 is ideally suited for use in RAID systems. Features such as Time-Limited Error Recovery (TLER) and advanced Error Correction Code (ECC) ensure that data errors are efficiently detected and corrected, significantly improving data integrity in complex storage architectures. With a storage capacity of 20 TB per drive, it offers a cost-effective solution for archiving large volumes of data and scaling your infrastructure. Choose a hard drive that perfectly combines performance, capacity and reliability.
