The Western Digital Red Plus 4TB (WD40EFZZ) is specifically engineered for small to medium business NAS environments and home office servers. Packed with power to handle the increased workloads of a networked standby system, this drive features CMR (Conventional Magnetic Recording) technology to ensure seamless integration and data consistency in RAID and multi-bay configurations.

Professional Features

• NASware™ 3.0 Technology: Built into every drive to optimize performance, increase compatibility, and improve reliability within your NAS or server system.
• CMR for RAID Stability: Unlike SMR drives, Red Plus uses CMR technology to maintain high performance and avoid data “re-writing” issues in demanding RAID rebuilds.
• 24/7 Environment Ready: Designed to run cool and quiet, offering the durability needed for always-on environments with up to 8 bays.
• Enhanced Shock Protection: Features a multi-axis shock sensor that automatically detects subtle shock events and compensates to protect your critical data.
