More Specifications

The Western Digital 0F38785 Ultrastar DC HC560 20TB is a high-capacity, high-performance hard drive that is designed for use in data centers and other enterprise storage environments. It has a storage capacity of 20 terabytes, which is equivalent to 20,000 gigabytes.

The drive uses the Serial Attached SCSI (SAS) interface with a 12 Gbps transfer rate, which is the latest standard for SAS interface and offers faster data transfer speeds than the previous SAS-6 Gbps interface. It also uses Western Digital's advanced technologies to help ensure reliable data storage and retrieval.

The drive is designed to meet the needs of enterprise storage environments, providing high-performance data access, high-density storage, and reliability. Additionally, the drive has a mean time between failures (MTBF) of 2.5 million hours, which is a measure of the drive's reliability and indicates that the drive is designed to last for many years of continuous use.

The Ultrastar DC HC560 series also includes advanced data security options such as TCG-compliant self-encryption (SED) and Instant Secure Erase (ISE)

High Reliability

The Western Digital 0F38785 Ultrastar DC HC560 20TB is designed with high reliability in mind. It uses advanced technologies to help ensure reliable data storage and retrieval. The drive is built with features such as HelioSeal technology which hermetically seals the drive to protect it from environmental elements such as dust, humidity, and temperature changes.

It also features a dual-stage micro actuator which improves the drive's head positioning accuracy, and StableTrac which secures the motor shaft at both ends to reduce system-induced vibration and stabilize platters for accurate tracking. These technologies help to improve the drive's overall reliability.

Additionally, it has a mean time between failures (MTBF) of 2.5 million hours, which is a measure of the drive's reliability and indicates that the drive is designed to last for many years of continuous use. This MTBF rating is one of the highest in the industry and is a testament to the drive's high reliability. The drive also has an advanced error correction and recovery features to help ensure the integrity of data stored on the drive.

The Western Digital Ultrastar DC HC560 20TB is designed with high reliability in mind, using advanced technologies to protect the drive from environmental elements, improve the drive's head positioning accuracy, reduce system-induced vibration, and advanced data security options. It also has a very high MTBF rating of 2.5 million hours, advanced error correction, recovery features, making it a suitable solution for enterprise storage environments where high-performance, scalability, and high reliability are required.


The Western Digital 0F38785 Ultrastar DC HC560 20TB is generally compatible with most devices and systems that use the Serial Attached SCSI (SAS) interface and support the SAS-12 Gbps interface. It is designed for use in data centers and other high-performance storage environments and is compatible with most operating systems such as Windows, MacOS, Linux, and UNIX.

It can be used in servers, network-attached storage (NAS) devices, and storage area networks (SANs) as well as in data centers, cloud storage, and other demanding enterprise applications.

The Western Digital Ultrastar DC HC560 20TB is generally compatible with most devices and systems that use the SAS interface and support the SAS-12 Gbps interface, but it's always important to check the system requirements, compatibility, proper formatting and power supply before installing the drive to ensure optimal performance.

When it comes to storing files and processing information, it is difficult to shove the impressive SATA hard drives aside. Although many people tend to regard hard disk drives as old technology, the new highly performing variants have raised the bar. One of the most impressive variants is hard drives with the SATA interface and transfer speed of up to 6Gbps.

These are among the best drives to buy presently. They come with flash-speed disks that load several times faster than traditional hard drives. Another added advantage is that they come in either 2.5-inch sizes or 3.5-inch sizes. Users can find SATA 6Gbps hard drives that will nicely fit their case or enclosure.

SATA 6Gbps hard drives are designed to offer maximum performance. They connect to servers, PCs, or desktop computers via SATA 6Gbps cables. Despite their compact 2.5" to 3.5" sizes, they feature a dynamic cache of up to 64MB. Having these types of storage devices in hand will improve work efficiency and productivity.

Improved Storage Capacity and Performance

There are SATA 6Gbps hard drives that can give users a blend of HDD and SSD functionality. A device that can give a synergistic effect of both storage units will surely offer a higher level of performance. Users will find drives with traditional storage capacity up to 18TB. Most of these drives also come along with NAND technology for enhanced performance.

The read-write speed is something that will give users optimum satisfaction. With the SATA 6Gbps interface, users can expect read speed up to 400MB/s. Not only that, but some drives also run at up to 10000 rpm. Even at that rate, they are generally quiet, and they generate less heat.

Drives that use the SATA 6Gbps interface have been built to learn users' most used applications effectively. This engineering allows them to load those applications faster. It also helps with gaming consoles to load the games initially after users have launched the game. There is everything to get excited about when it comes to these drives.

The point of the SATA 6Gbps interface is to enhance the quality of the traditional mechanical hard drives. They are available at different capacity choices and RPM choices.

Reliable Data Recovery

There are possibilities of data accidents such as accidental deletion, formatting, virus attack, unexpected power shutdown, and partition loss. If such losses occur, data recovery software can easily recover the data from SATA 6Gbps hard drives. Data can be easily recovered, undelete, and unformatted from these SATA hard drives

Dynamic Cache

The dynamic cache is one of these drives' most impressive features despite not being so evident to users. It improves the performance of the SATA 6Gbps drives in real-time with optimized cache allocation. This function allocates more cache towards the read and writes functions. That is why users will find that read and write speeds are usually almost equal.
