Aimed at 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 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 simplify hard drive selection. This unique algorithm is optimized for NAS systems and provides the right balance of performance and reliability in NAS and RAID environments. In short, WD Red Pro is the most compatible hard drive for NAS enclosures. And the numbers back it up. WD Red Pro hard drives are the result of extensive compatibility testing and extensive technology integration with these NAS partners. Shock protection for drive bays in large NAS systems - WD Red Pro hard drives feature a multi-axis shock sensor to detect even minor impacts and a dynamic head-height adjustment that automatically compensates for shock during each read/write operation to protect your data. The combination of these technologies provides even more protection for hard drives in large 24-bay NAS environments and increases hard drive reliability. 3D Active Balance Plus - Advanced two-level mass balance technology
