Built for NAS arrays up to eight bays
The Western Digital WD30EFPX is a 3TB CMR hard drive designed for network-attached storage in home offices and small-to-medium businesses. Its conventional magnetic recording handles continuous multi-user workloads such as file sharing, backup and media streaming. The 3.5-inch form factor fits standard drive trays in compatible NAS enclosures.
CMR recording with 256 MB cache
Conventional magnetic recording avoids the rewrite penalties of shingled drives, keeping sustained throughput steady during heavy read and write activity. The 256 MB cache absorbs burst traffic and smooths random I/O across the SATA 6.0 Gb/s interface. This combination makes the drive suitable for RAID arrays that demand predictable latency.
Low-RPM acoustics and modest power draw
Spinning at 5400 RPM, the drive runs quieter than faster desktop models and generates less heat inside a multi-bay chassis. Typical idle and active power consumption stays within the thermal envelope of compact NAS appliances. The 26.1 mm z-height matches the standard 3.5-inch drive bay used by most enclosures.
