  • Usage

    NAS

    Disks for use in NAS (Network-Attached Storage) systems that provide access to data from all devices on a network. They are designed for continuous operation with other such disks in RAID configurations to protect data from failures.

    Recorder

    Hard drives for use in recording devices for surveillance camera systems.

  • 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).

    SATA III

    A modern hard disk connection standard that offers twice the maximum speed compared to SATA II.

    The majority of hard disks use this standard.

    The motherboard must support it for the disk to operate at its maximum potential.

  • 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.

Offers high IOPS with proven technology

A unique hardware combination, tested in real-world conditions with the latest innovative technologies, allows these air-based units to deliver high IOPS ratings for data-intensive applications.

Optimized performance and durability

Optimized performance to provide higher access densities (IOPS/TB) in data-intensive applications, with proven durability.

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.

Protection from & Vibration

Disturbances caused by increased vibration are expected and proactively compensated for by Rotation Vibration (RV) sensors, and discrete vibration events are automatically detected by multi-axis vibration sensors and compensated for using dynamic altitude technology to maintain performance and protect data.
