With drives up to 10TB, WD RedTM drives offer a wide array of solutions for customers looking to build a NAS storage solution.

Exclusive NASware 3.0

Built into every WD RedTM hard drive, NASware 3.0's advanced technology improves your system's storage performance by increasing compatibility, integration, upgradeability, and reliability.
Built for optimum NAS compatibility
Desktop drives aren't purpose-built for NAS. But WD RedTM drives with NASware technology are. Our exclusive technology takes the guesswork out of selecting a drive. WD RedTM drives are for small NAS systems, and our unique algorithm balances performance and reliability in NAS and RAID environments. Simply put, a WD RedTM drive is one of the most compatible drives available for NAS enclosures. But don't take our word for it. WD RedTM drives are a reflection of extensive NAS partner technology engagement and compatibility-testing resulting in a leading compatibility list for NAS systems.
Desktop drives vs. WD RedTMIn 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:
- 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 under those conditions. WD RedTM drives are.
- Error recovery controls: WD RedTM 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 RedTM drives are designed for multi-bay NAS systems.
