Твърд диск 4TB Western Digital Red Plus NAS (WD40EFPX), SATA 6Gb/s, 5400 rpm, 256MB кеш, 3.5" (8.89 cm)

For Small or Medium Businesses 
Stream, backup, share, and organize your digital content with a NAS and WD Red™ Plus drives designed to effortlessly share content with the devices at your home or business. NASware™ technology increases your drives’ compatibility with your existing network and devices. For larger businesses with up to 24 bays, count on WD Red™ Pro drives to deliver exceptional performance.

• 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.
