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.

Questions sur cet article

What does the 5400 RPM speed mean for daily NAS use?

The 5400 RPM spindle provides steady throughput for multi-user file access and media streaming in NAS enclosures with up to eight bays.

How does the SATA 6.0Gb/s interface affect real-world transfer rates?

The SATA 6.0Gb/s link connects the 256MB cache to the host, letting burst transfers reach the interface limit while sustained speeds follow the mechanical design.

Will the 3.5-inch form factor fit my NAS tray?

The drive measures 147.00mm long, 101.60mm wide and 26.10mm high, matching the standard 3.5-inch drive bay used in most NAS chassis.
