  • Usage

    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.

    5400

    The slowest hard disk drives (HDD) are typically used for storing large volumes of data that are not frequently accessed (e.g. for backups). They are not recommended for installing programs and games.

Description

Description

WD Blue internal hard drives offer reliability for office and web applications. They are ideal for use as primary drives in desktop computers and for office applications. With a range of capacities and cache sizes, there is a WD Blue internal hard drive that is just right for you.

NoTouch Ramp Load Technology:
The recording head never touches the disk media, ensuring significantly less wear on the recording head and the media, as well as better protection of the drive during transport.

Low power consumption
State-of-the-art seek algorithms and advanced power management features ensure low power consumption.

Tested for compatibility.
We test hundreds of systems and a wide range of platforms in the FIT Lab to provide our customers with the confidence that our drives will work in their systems.

Upgrading your drive is easy.
Seamlessly migrate your current system to the new Western Digital drive using the Acronis® True Image™ WD Edition software, available for free download from the Western Digital support website. This software allows you to copy all your data to a new drive, so you don't need to reinstall your operating system to take advantage of all the benefits of a new drive.

The Western Digital advantage
Western Digital subjects our products to extensive Functional Integrity Testing (FIT) before releasing any product. On average, each new product undergoes 600,000 hours of testing. Western Digital also has a detailed knowledge base with more than 1,000 helpful articles. You can also call support toll-free 7 days a week in the US and Canada. Please refer to the Western Digital support website for more details. Recommended use – WD Desktop hard drives are tested and recommended for use in computers, industrial applications, and external enclosures. 2

    It is very early to talk about the reliability of the disk from this purchase (10th/24), but I bought it 2 years ago and it has been working since then in a recorder where it operates 24/7 without any problems. For this specific use, it successfully does the job for which it was purchased.

    I have been dealing with computers for about 40 years and I have never had a Western Digital hard drive fail on me. From all the other companies that manufacture hard drives, I have had some unpleasant experiences at some point.
    The Blue series of hard drives does not have top performance because it has a lower rotation speed. However, for this reason, it does not increase temperature, does not consume much energy, and is not subject to high mechanical stress. These characteristics make it an excellent choice when the goal is long-term data storage and not operating system installation.
    Of course, I am referring to normal operating conditions. For example, if your computer case does not cool properly, then no hard drive will work as it should, resulting in reduced performance and often, reduced product lifespan. However, Western Digital never failed me...
