  • Key Specs
    • Storage Capacity: 18000 gigabytes (Measured in megabytes (MB), gigabytes (GB) and terabytes (TB), this is the amount available for storing files, music, movies, photos and more. The total includes the capacity of the hard disk drive and solid state drive if both are included on the computer.)
    • Storage Drive Type: HDD (Traditional, mechanical hard disk drives are the most common type of storage because they're relatively inexpensive and offer huge capacities. However, they also generate both noise and heat. Solid state drives, also known as SSDs, are many times faster than hard disk drives and have no moving parts to wear out, but typically offer less capacity for the same price.)
    • Rotational Speed: 7200 revolutions per minute (The rate at which the hard drive spins its platters. The higher the rotational speed, the faster the drive can read and write data.)
    • Maximum Read Speed: 272 megabytes per second (The greatest speed at which the device can read information; for example, opening files.)
    • Maximum Write Speed: 272 megabytes per second (The greatest speed at which the device can write information; for example, saving files.)
    • Form Factor: 3.5 in.
    • Interface(s): SATA (Refers to the types of connections that devices use to interact and communicate with each other.)

Designed for power users to medium-sized organizations in RAID-optimized NAS systems with up to 24 bays. Perfect for archiving, sharing, and protecting rapidly growing amounts of data.

  • Demands of Big Business: Designed specifically with medium or large scale business customers, WD Red Pro drives are available for up to 24-bay NAS systems. Engineered to handle high-intensity workloads in 24x7 environments. Ideal for archiving and sharing, as well as RAID array extended systems.
  • Technology: Exclusive advanced firmware technology, NASware 3.0, enables seamless integration, robust data protection and optimal performance for NAS systems operating under heavy demand. Improves storage performance by increasing compatibility, integration, upgradeability, and reliability.
  • Compatibility: Optimized for NAS systems, unique algorithm balances performance and reliability in NAS and RAID environments. WD Red Plus drive is one of the most compatible drives available for NAS enclosures. Reflection of extensive NAS partner technology engagement and compatibility testing.
  • Protection: WD Red Pro drives are equipped with a multi-axis shock sensor that automatically detects subtle shock events and dynamic fly height technology which adjusts each read-write function to compensate and protect the data. Protects the drives in larger 24-bay NAS environments.
  • 3D Active Balance: Our enhanced dual-plane balance control technology improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multi-drive system, reduce the hard drive life span, and degrade the performance.
  • Error Recovery Prevention: Built specifically for RAID and NAS environments, WD Red Pro drives come equipped with error recovery controls as part of NASware 3.0 technology to help reduce drive fallout in RAID applications
  • Extended Drive Testing: NAS environment that has up to 24 bays is very demanding on a hard drive with add?ed vibration and heat. This is why every WD Red Pro drive is shipped with extended thermal cycle burn-in testing to help ensure each drive is tested for extended reliable operation
  • Longer Warranty Coverage: WD Red Pro drives comes with a 5-year limited warranty for an even greater peace of mind.

    Works great, smidge noisy

    Hard drive works great. It has been running 24 hours straight since I purchased. Subtle noise, but annoying but otherwise fine.

    Good drive

    A little slow to spin up. A little noisy at first. Other than that, I have no other issues. Speed is good. Works great with my NAS. Tons of space. I’ve always trusted WD drives.

    Excellent NAS Drive - Waited for price drop

    I have been using WD drives for over 15 years with no issues. Therefore, I was not surprised to find that this 18 TB drive is an excellent drive. However, the first drive I received was defective and could not be formatted, which caused Windows Explorer to freeze. The second drive I received was without fault and now have it running in my home NAS.
