  • Usage Server

  • Communication Protocol

    Hard drives communicate with the computer through a protocol.

    There are two protocols for HDD hard drives, SATA (for simple use) and SAS (high reliability for corporate use).

    SAS 3.0

    A modern connection standard with high reliability aimed at corporate use.

    The motherboard should have a corresponding connection.

  • Cache Size

    Intermediate temporary memory between the disk and the computer, allowing the hard disk to provide faster and more immediate access to data. It does not have any particular benefit for the average user.

  • Form Factor

    The size of the HDD hard drive.

    3.5

    The classic size of a desktop computer hard disk drive (HDD).

  • Rotation Speed

    The most important feature along with capacity is that the faster the rotation speed of a hard disk, the faster the access and storage of data it can provide.

    7200

    The most popular HDD hard drives, about 33% faster than 5400. Suitable for all uses such as installing programs and games. For installing the operating system, programs, and games, SSD are even faster and remain the best choice.

Handle Data Center Workload with Proven Technology

The combination of proven hardware with the latest innovative technologies offers the performance, capacity, and reliability needed to manage high-intensity workloads in multi-user data centers, 24/7.

Increase Capacity while Reducing Cost

Western Digital's energy-assisted perpendicular magnetic recording (ePMR) technology allows customers to increase capacities while simultaneously reducing total cost of ownership (TCO), including both $/TB and operational expenses (OpEx).

Rapid certification and integration

The utilization of hardware designs from generations of highly successful products ensures easy certification, seamless integration, and rapid adoption by existing customers.

Reliability You Can Trust

Manufactured from the same platform that has been developed in thousands of data centers around the world, these units provide top-notch and proven reliability for easy data storage.

Increase Density with Low Power

Western Digital's triple state actuator (TSA) increases tracks per inch (TPI) while providing greater control over the actuator arm, allowing for higher capacities with low power.
