WD Red drives are for small NAS systems, and our unique algorithm balances performance and reliability in NAS and RAID environments. Simply put, a WD Red drive is one of the most compatible drives available for NAS enclosures. But don't take our word for it. WD Red drives are a reflection of extensive NAS partner technology engagement and compatibility-testing resulting in a leading compatibility list for NAS systems. Highlights Desktop Drives vs. WD Red * Specifically designed for use in NAS systems with up to 8 bays In a Network Attached Storage device, a desktop hard drive is not typically designed for NAS environments. Do right by your NAS and choose the drive designed for NAS with an array of features to help preserve your data and maintain optimum performance. Take the following into consideration when choosing a hard drive for your NAS: * Supports up to 180 TB/yr workload rate* * NASware technology for compatibility * 3-year limited warranty * Small and home office NAS systems in a 24x7 environment INTERFACE SATA 6 Gb/s FORM FACTOR 3.5 and 2.5-inch CAPACITIES 3.5-inch: 1TB to 10TB 2.5-inch: 1TB MODEL NUMBERS 3.5-inch: WD100EFAX WD80EFAX WD80EFZX WD60EFRX WD40EFRX WD30EFRX WD20EFRX WD10EFRX 2.5-inch: WD10JFCX THE WESTERN DIGITAL ADVANTAGE Western Digital puts our products through extensive Functional Integrity Testing (F.I.T.) prior to any product launch. This testing ensures our products consistently meet the quality and reliability standards of the Western Digital brand. WD also has a detailed Knowledge Base with more than 1,000 helpful articles as well as helpful software and utilities. Our toll-free customer support lines are here to help or you can access our WD Support site for additional details. * Compatibility: Without being tested for compatibility with your NAS system, optimum performance is not guaranteed. * Reliability: The always-on environment of a NAS or RAID is a challenging one. And desktop drives aren't typically designed and tested under those conditions. WD Red drives are. * 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. * 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 drives are designed for multi-bay NAS systems.

Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second.

Controlled unload at ambient condition. MTBF specifications are based upon internal testing using a 40C base casting temperature. MTBF is based on a sample population and is estimated by statistical measurements and acceleration algorithms. MTBF does not predict an individual drive's reliability and does not constitute a warranty. Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred X (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations.
