Desktop Drives vs. WD Red™ Plus
Do right by your NAS and choose the drive purpose-built 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: Unlike desktop drives, these drives are specifically tested for compatibility with NAS systems for optimum performance. • 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 like WD Red™ Plus drives are. • Error Recovery Controls: WD Red™ Plus NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system. • 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™ Plus drives are designed to thrive in multi-bay NAS system environments.
Designed with CMR technology for small or medium-sized businesses in RAID-optimized NAS systems with up to 8 bays. Perfect for handling increased workloads, including expanded OS compatibility and ZFS.
WD's exclusive NASware technology, built into every WD Red hard drive, improves NAS storage performance by reducing common hard drive concerns in NAS systems including concerns for things like compatibility, integration, upgradeability, reliability and cost of ownership that are experienced with a hard drive designed for desktop computers.
