Designed for high-intensity workloads in 24x7 environments, the WD Red Pro family is ideal for archiving and sharing content as well as building RAID arrays in advanced operating systems such as ZFS and other file systems. These hard drives increase efficiency by enabling your employees to quickly share files and reliably back up folders in your NAS solution.Designed for optimal NAS compatibility - WD Red Pro hard drives with NASware technology make hard drive selection easy. Our unique algorithm is optimised for NAS systems and provides the right balance of performance and reliability in NAS and RAID environments. In short: WD Red Pro is the hard drive with the highest compatibility for NAS enclosures. This is also proven by figures. WD Red Pro hard drives are the result of extensive compatibility testing and extensive integration of technologies from our NAS partners.Shock protection for drive bays in large NAS systems - WD Red Pro hard drives are equipped with a multi-axis shock sensor to detect even minor impacts and a dynamic head-height adjustment that automatically compensates for shocks during each read/write operation to protect your data. The combination of these technologies provides even more protection for hard drives in large NAS environments with 24 drive bays and increases the reliability of the hard drives.3D Active Balance Plus - The advanced two-level mass balancing technology significantly improves the overall performance and reliability of the drive.
