Rotational Speed: 7200 Revolutions Per Minute (RPM)

  • One of the defining characteristics of this HDD is its operational speed, measured in revolutions per minute (RPM). With a rapid rotation of 7200 RPM, the Ultrastar DC Hc560 ensures swift data access and retrieval, optimizing performance for data-intensive applications.

Interface: Serial Advanced Technology Attachment (SATA)

  • The SATA interface is the bridge that connects the hard disk drive to the motherboard. The Ultrastar DC Hc560 employs the SATA interface, a widely adopted standard known for its simplicity and compatibility. This makes the HDD seamlessly integrate into a variety of systems.

Data Transfer Speed: 6 Gigabytes Per Second (GBPS)

  • Data transfer speed is a critical factor in assessing storage performance. The Ultrastar DC Hc560 shines with its impressive data transfer rate of 6 gigabytes per second. This high-speed interface facilitates efficient data flow, reducing latency and enhancing overall system responsiveness.

Buffer Size: 512 Megabytes (MB)

  • The presence of a substantial buffer is instrumental in enhancing the HDD's ability to handle data. With a 512-megabyte buffer, the Ultrastar DC Hc560 can efficiently manage data transfers, reducing the likelihood of bottlenecks and ensuring a smooth user experience.

Advanced Format: 512e

  • The Ultrastar DC Hc560 adopts an advanced format known as 512e, which stands for 512-byte emulation. This technology optimizes storage capacity and performance by aligning with modern storage applications and overcoming the limitations of older formatting methods.

Form Factor: 3.5-inch Helium Platform

  • The physical dimensions of a hard disk drive are crucial, especially in densely populated data centers. The Ultrastar DC Hc560 adopts a 3.5-inch form factor, utilizing a helium platform. This not only contributes to a more compact design but also aids in heat dissipation, enhancing overall reliability and lifespan.

Optin and Technology

  • Optinand technology is a distinctive feature of the Ultrastar DC Hc560. This innovative addition optimizes the performance and reliability of the HDD by mitigating issues related to read and write operations. It contributes to the overall efficiency and longevity of the hard disk drive, making it an appealing choice for demanding data center environments.

Hot Swap & Drive Efficiency

  • The Western Digital Ultrastar DC Hc560 20TB SATA-6GBPS 512MB Buffer 512e Hard Drive (WUH722020BLE6L4) is designed for enterprise use and is compatible with hot-swap drive bays. This allows the hard drive to be easily replaced without the need to power down the system. This feature is particularly useful in mission-critical systems where downtime needs to be minimized.
  • The high storage capacity of 20TB allows for large amounts of data to be stored on the drive, while the 6Gbps SATA interface and 512MB buffer allow for fast data transfer rates. The 512e sector format increases the hard drive's capacity and efficiency.
  • It also features technologies such as Advanced Format and Advanced Power Management, which can help to increase the reliability and lifespan of the hard drive. Additionally, it has an MTBF (Mean Time Between Failures) rating of 2.5 million hours, which is significantly higher than consumer-grade hard drives.
  • It's important to ensure that the hot-swap drive bay is compatible with the hard drive's form factor and interface and also to check with the system or device manufacturer for any specific compatibility requirements.

Performance Optimization Through 512e Technology

The adoption of 512e technology in the Ultrastar Dc Hc560 contributes significantly to its performance optimization. In traditional hard disk drives, data was stored in 512-byte sectors. However, with evolving storage needs, the industry has transitioned to a more efficient 4K sector size.

The 512e technology serves as a bridge between these two sector sizes, allowing the Ultrastar Dc Hc560 to maintain compatibility with legacy applications while still capitalizing on the benefits of the 4K format. This results in enhanced storage capacity utilization and improved error correction capabilities, ultimately leading to a more robust and reliable data storage solution.

Ensuring Data Integrity: Se Security Features

Data integrity is paramount, especially in the context of data centers that handle sensitive and mission-critical information. The Ultrastar Dc Hc560 incorporates Se (Secure Erase) technology as part of its security features. This feature facilitates the secure deletion of data, ensuring that sensitive information is permanently and irreversibly removed from the drive. This is crucial for enterprises adhering to data protection regulations and standards.

Data Center-Centric Design

The Ultrastar DC Hc560 is purpose-built for data center environments, and its design reflects this focus. From its robust construction to its advanced features, every aspect of the HDD is tailored to meet the demands of modern data centers. Here are some key aspects of its data center-centric design:

Reliability and Durability

Data centers operate around the clock, and downtime is not an option. The Ultrastar DC Hc560 is engineered for reliability and durability, with components designed to withstand the rigors of continuous operation. This ensures that the HDD can meet the demanding performance expectations of data center environments.

Error Recovery and Correction

In data center operations, errors are inevitable. The Ultrastar DC Hc560 addresses this reality with advanced error recovery and correction mechanisms. These features work in the background to identify and rectify errors, preventing data loss and ensuring the integrity of stored information.

Vibration and Temperature Management

Data center racks can be prone to vibrations, and maintaining optimal temperatures is crucial for the health of storage devices. The Ultrastar DC Hc560 incorporates vibration resistance and temperature management features to ensure consistent performance even in challenging environmental conditions.

Compatibility and Integration

Compatibility with existing infrastructure is a key consideration for data centers looking to upgrade or expand their storage capacity. The Ultrastar DC Hc560's design prioritizes compatibility, making it easy to integrate into diverse data center configurations without requiring extensive modifications.

High-Speed Data Transfer

  • The Western Digital Ultrastar DC HC550 20TB hard drive (model number WUH722020BLE6L4) is a high-capacity, enterprise-class hard drive designed for use in data center environments. It features a storage capacity of 20TB, a rotation speed of 7.2K RPM, and a SATA (Serial ATA) interface with a 6 Gbps data transfer rate.
  • The 6 Gbps data transfer rate of the SATA interface allows the drive to transfer data at a maximum rate of 6 Gbps, which is approximately 600 MB/s. This is the theoretical maximum transfer rate, and actual transfer rates may be lower depending on the specific system configuration and workload. However, it is slower than the SAS interface, which can provide faster data transfer speed.
  • The 512MB of cache on this drive also helps to improve performance by allowing the drive to store frequently accessed data for quick retrieval.
