WD Ultrastar DC HC570 22 TB Hard Drive — 3.5" SATA Enterprise HDD (CMR, 7200 RPM)

Meet the WD Ultrastar DC HC570 0F48155, a purpose-built 22 TB hard drive designed for data centers, storage arrays, and high-demand workloads. This 3.5-inch internal drive uses a SATA (SATA/600) interface and Conventional Magnetic Recording (CMR) to deliver dependable capacity with steady throughput. Built for continuous operation, it combines enterprise-grade reliability with a warranty that backs its performance in the field. Whether you’re expanding an archival pool, scaling a virtualization cluster, or building a resilient backup repository, the DC HC570 sets a new standard for density and durability in demanding environments.

• Massive capacity with 22 TB per drive, ideal for long-term archives, media libraries, backups, and data-intensive workloads. The substantial capacity reduces the number of drives needed, lowering hardware footprint and simplifying management in data centers and on-premises storage arrays. This density is especially valuable when provisioning large repositories, video libraries, scientific datasets, or cloud storage backends that demand scalable growth over time.
• Enterprise-grade performance to meet demanding workloads. With a 7200 RPM spindle and CMR architecture, this Ultrastar drive provides reliable data access and steady transfer rates across heavy read/write cycles. This translates to better sustained throughput for virtualization hosts, analytics pipelines, backup windows, and database shuffles, helping to protect service levels in busy data environments.
• Broad compatibility and easy integration. The drive uses a SATA 6Gb/s interface and a standard 3.5-inch form factor, making it compatible with a wide range of servers, chassis backplanes, and RAID controllers. Its conventional SATA connection is straightforward to deploy in existing storage infrastructure without the need for specialized adapters, enabling rapid scale-out or upgrade paths for data centers and enterprise storage arrays.
• Data integrity and reliability are at the forefront of the design. The DC HC570 employs 512e sector format compatibility to maximize interoperability with modern operating systems while delivering robust error recovery and stable performance under continuous operation. Coupled with a 5-year warranty, this drive is built to withstand the rigors of enterprise workloads, long idle periods, and frequent data access without sacrificing reliability.
• Versatile, scalable deployment. Ideal for data centers, cloud storage, virtualization clusters, high-capacity NAS, backups, and disaster recovery repositories, the DC HC570 delivers the density and durability required for today’s data-heavy workloads. This drive is a dependable backbone for large-scale storage ecosystems, enabling efficient data management, easier capacity planning, and long-term cost efficiency.

How to install WD Ultrastar DC HC570 22 TB Hard Drive

• Power down your server, workstation, or storage array and unplug from power to begin installation. Handling a live system can risk data integrity and component damage; ensure you’re following your data center’s safety and ESD guidelines.
• Open the drive bay or hot-swap enclosure and carefully insert the 3.5-inch DC HC570 into an available slot, ensuring the connector aligns with the backplane. Gently push the drive until it seats securely and the latching mechanism engages as required by your chassis.
• Connect the SATA data cable to the motherboard or RAID controller and attach the power connector from the power supply. If your system uses a backplane, simply slide the drive into the slot until it seats securely and the backplane detects the device automatically.
• If using a RAID controller, configure the new disk per controller guidelines, assign to an array, and initialize the disk as required. Follow your storage management software prompts to optimize for your workload, whether you’re creating a new array or expanding an existing one. Ensure proper hot-spare settings if applicable.
• Boot the system, initialize and format the drive with the desired file system (for example NTFS, ext4, or XFS) based on your operating system and workload requirements. Confirm drive health and monitor SMART attributes through your management tools to maintain ongoing reliability and performance.
