Fill Your NAS with WD Red Built for 1 to 8-bay NAS systems, WD Red lets users store their data in one unit. NASware 3.0 Technology Built into every WD Red hard drive, NASware 3.0's technology helps improves your system's storage performance by increasing compatibility, integration, upgradeability, & reliability. Built for NAS Compatibility Desktop drives aren't purpose-built for NAS, but WD Red drives with NASware are. WD's technology helps takes the guesswork out of selecting a drive. WD Red is for small NAS systems & WD's algorithm balances performance & reliability in NAS & RAID environments. Desktop Drives vs. WD Red Desktop hard drives are not designed for NAS environments. Do right by your NAS & choose a drive with an array of features to help preserve your data & maintain optimum performance. Take the following into consideration when choosing a hard drive for your NAS: Compatibility
- Without being tested for compatibility with your NAS system, enhanced performance is not guaranteed Reliability
- The always-on environment of a NAS or RAID is a hot one & desktop drives aren't typically tested in those conditions. WD Red is Error Recovery Controls
- WD Red NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system. Desktop drives are not typically designed for RAID environments where this can be an issue Noise & Vibration Protection
- Designed to operate solo, desktop drives offer little or no protection from the noise & vibration faced in a multi-drive system. WD Red drives are designed for multi-bay NAS systems WD Red for Home Stream, backup, share, & organize your digital content at home with a NAS & WD Red drives designed to share content to the devices in your home. Red NASware helps increase your drives' compatibility with your devices, TV, stereo, & more WD Red for Small Business WD Red is a good hard drive choice for 1 to 8 bay systems. NASware 3.0 allows for integration with your existing network so WD Red can share & backup files at the speed of your business. For larger businesses with up to 16 bays, use WD Red Pro 3D Active Balance Plus This helps ensure your data is protected from excessive vibration & noise in a NAS or RAID environment. This dual-plane balance control helps reduce the degradation of your drive over time Reliability Since your NAS system is always on, a reliable drive is essential. With an MTBF of up to 1 million hours, the WD Red drive with NASware 3.0 is designed for 24x 7 environments Cooler Operations By reducing power consumption, the operating temperature of your NAS stays cooler.
