The Western Digital WD40EFPX is an internal hard drive that offers 4 TB of capacity and fits standard 3.5 inch bays in network attached storage enclosures. It connects through a SATA 6 Gb/s interface, so installation in most popular NAS systems takes only a few minutes.

A 5400 RPM motor works with a 256 MB cache to deliver sustained transfers up to 180 MB/s, giving teams the speed they need for shared documents, media libraries, or system backups. Western Digital includes NASware firmware, which fine-tunes power management, error recovery, and command handling so each drive plays well with RAID controllers and other drives in the array.

The drive is rated for round-the-clock operation, making it a dependable choice for small or growing businesses that run file servers day and night. Home users who host a Plex library, safeguard family photos, or back up multiple PCs will also appreciate its quiet operation and low power draw. Integrated vibration protection keeps multi-bay systems stable, and a three-year limited warranty adds extra peace of mind.

Highlights:
  • 4 TB storage capacity
  • 3.5 inch form factor that installs easily inside most NAS enclosures
  • SATA 6 Gb/s interface
  • 5400 RPM class motor
  • 256 MB cache for smoother data flow
  • Up to 180 MB/s sustained transfer rate
  • NASware firmware improves compatibility and data protection
  • Optimized for NAS systems with up to eight bays
  • Engineered for 24 / 7 operation
  • Three-year limited warranty
