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: 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 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. Stream, backup, share, and organize your digital content at home with a NAS and WD Red drives designed to effortlessly share content with the devices in your home.
