WD - Red Pro 3.5" SATA III Internal NAS Hard Drive - 256MB Cache, 4TB, Single

Enterprise-class hard drives engineered to deliver high performance and reliability to commercial and enterprise NAS environments WD Red Pro drives are engineered to handle high-intensity workloads in 24x7 multi-user commercial and enterprise NAS environments. WD Red Pro drives deliver the performance, scalability and dependability businesses require to store, share and collaborate on large amounts of data in multi-bay RAID-optimized NAS systems.Optimized for NAS with NASware Western Digital's exclusive NASware technology fine tunes drive parameters to match NAS system workloads, which helps increase performance and reliability. Designed for Continuous Operation WD Red Pro hard drives are designed to handle the rigorous demands of high-intensity 24x7 multi-user NAS environments and increase system durability. Tested for Dependable Compatibility Western Digital partners with a wide range of NAS system vendors for extensive testing to ensure compatibility with most NAS enclosures.Protected Against Excessive Vibration WD Red Pro drives include Rotation Vibration (RV) sensors that anticipate and proactively counteract disturbances caused by increased vibration. By dispersing excess vibration across the drive chassis, turbulence is minimized, performance is maintained and drives are protected. Built to Absorb ShockWD Red Pro hard drives include a multi-axis shock sensor to detect subtle shock events and automatically compensate with dynamic fly height technology to further protect the drives in NAS enclosures. Desktop drives vs. WD Red Pro It is important to choose a drive purpose-built for RAID-optimized NAS systems to ensure optimum performance and preserve your valuable data. Take the following into consideration when choosing a hard drive for your NAS. CompatibilityUnlike desktop drives, WD Red Pro hard drives are specifically designed and tested for NAS and include NASware technology which fine tunes drive parameters to match NAS system workloads for optimum performance.ReliabilityDesktop drives aren't typically designed for the demands of an always-on NAS environment. WD Red Pro hard drives are designed to perform under tough conditions encountered in high-intensity 24x7 multi-user NAS environments. RAID Ready WD Red hard drives are engineered with RAID error recovery control to help reduce failures within multi-bay NAS systems, unlike most desktop drives that are configured for generic use.Noise and Vibration Protection Designed to operate solo, desktop drives typically offer little or no protection from the noise and vibration present in a multi-drive system. WD Red hard drives include Rotation Vibration (RV) sensors that anticipate and proactively counteract disturbances caused by increased vibration often found in multi-bay NAS systems.
