Not just any drive will do. In single-bay to 8-bay NAS systems, WD Red raises the bar. Get as much as 64TB capacity, and with WD's exclusive NASware 3.0, you can optimize every single one of them. Built into every WD Red hard drive, NASware 3.0's advanced technology improves your system's storage performance by increasing compatibility, integration, upgradeability, and reliability.
Desktop drives aren't purpose-built for NAS. But WD Red drives with NASware are. Our exclusive technology takes the guesswork out of selecting a drive. WD Red is for small NAS systems, and our unique algorithm balances performance and reliability in NAS and RAID environments. Simply put, WD Red is the most compatible drive available for NAS enclosures. But don't take our word for it. WD Red is a reflection of the most extensive NAS partner compatibility-testing list that is available on the market.*
*Compatibility list as of March 2016
In a Network Attached Storage device, a desktop hard drive is not designed for NAS environments. Do right by your NAS and choose the drive with an array of features to preserve your data and 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, optimum performance is not guaranteed.
- Reliability: The always-on environment of a NAS or RAID is a hot one. And desktop drives aren't typically designed and 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 typically not designed for RAID environments where this can be an issue.
- Noise and Vibration Protection: Designed to operate solo, desktop drives offer little or no protection from the noise and vibration faced in a multi-drive system. WD Red drives are designed for multi-bay NAS systems.
Stream, backup, share and organize your digital content at home with a NAS and WD Red drives designed to effortlessly share content to the devices in your home. Red NASware increases your drives' compatibility with your devices, TV, stereo and more. Live in a connected world.
Businesses thrive on productivity and efficiency – two of the guiding principles built into the design of WD Red. It's the hard drive of choice for 1 to 8 bay systems. NASware 3.0 allows for seamless integration with your existing network so WD Red can share and backup files at the speed of your business. And for larger businesses with up to 16 bays, count on WD Red Pro.
