WD Red Pro 3.5" Internal Hard Drive 18TB NAS SATA3

Specially designed for medium or large businesses, WD Red Pro drives are available for NAS systems with up to 24 bays.
WD Red Pro is designed to handle high-intensity workloads in environments that run 24 hours a day, every day. It's ideal for archiving and sharing content, as well as reconfiguring RAID arrays on extended operating systems, such as ZFS or other file systems. These drives add value to your business by letting employees quickly share their files and back up their folders to a NAS solution.
NASware 3.0 Technology.
Our advanced, exclusive firmware technology, NASware 3.0, enables seamless integration, robust data protection and optimal performance for systems operating in demanding NAS environments. Advanced NASware 3.0 technology, included in every WD Red Pro hard drive, improves storage performance by increasing compatibility, integration, reliability and upgradeability.
Built for optimal NAS compatibility.
WD Red Pro drives with NASware technology make choosing a drive far easier. Our unique NAS-optimised algorithm balances performance and reliability in NAS and RAID environments. Simply put, WD Red Pro is one of the most compatible drives available for NAS devices. But you don't have to take our word for it. WD Red Pro drives come with an extensive record of compatibility testing and technology engagement from our NAS partners.
Shock protection for larger-bay NAS environments.
WD Red Pro drives are equipped with a multi-axis shock sensor that automatically detects even the smallest impacts, and dynamic head flying height technology that adjusts each read/write function in real time to compensate for movement and protect data. This combination of technologies further protects drives in large 24-bay NAS environments and increases their reliability.
3D Active Balance Plus.
Our enhanced dual-plane balance control technology increases overall drive performance and reliability. Hard drives that aren't properly balanced can produce excessive vibration and noise in a multi-drive system, which shortens hard drive lifespan and degrades performance over time.
Error recovery.
Specifically designed for RAID and NAS environments, WD Red Pro drives are equipped with error recovery controls as part of NASware 3.0 technology, which helps reduce drive issues in RAID applications.
More performance testing.
A NAS environment with up to 24 bays is very demanding on hard drives, producing more vibration and higher temperatures. For this reason, every WD Red Pro hard drive undergoes extensive thermal cycle performance testing, which helps ensure every drive is tested for reliable operation.
Longer warranty coverage.
WD Red Pro drives come with a 5-year limited warranty for extra peace of mind.
Desktop drives vs WD Red Pro.
Choose the drive specifically designed for NAS that's right for your system, with a range of features to help protect your data and ensure optimal performance. Keep the following points in mind when choosing a hard drive for your NAS:
-Compatibility: unlike desktop drives, these drives have undergone specific testing for compatibility with NAS systems to ensure optimal performance.
-Reliability: the always-on environments of a NAS or RAID system experience elevated temperatures. Desktop drives are not usually designed for these conditions or tested accordingly, whereas WD Red Pro drives are.
-Error recovery controls: WD Red Pro NAS hard drives are specifically designed with RAID error recovery control that helps reduce NAS system failures.
-Noise and vibration protection: designed to operate independently, desktop drives usually offer little to no protection against the noise and vibration that affect multi-drive systems. WD Red Pro drives are designed to excel in environments with multi-bay NAS systems.
