1TB NAS drive for small arrays

The WD Red Plus WD10EFRX is a 1TB 3.5-inch hard drive built for NAS enclosures. It uses a SATA 6.0Gb/s interface and conventional magnetic recording. The drive targets small or medium business NAS systems that run continuously.

180 TB per year workload ceiling

Rated for up to 180 TB per year, the drive handles typical multi-user file sharing and backup loads across up to 8 bays. The 5400 RPM class and 64MB cache deliver steady throughput for sequential workloads. Sustained random I/O or heavy database work will exceed its design envelope.

CMR reliability with NASware firmware

Conventional magnetic recording avoids the write penalties of shingled designs. NASware firmware optimises error recovery and power management for 24x7 operation. The bare-drive packaging means you supply mounting screws and cables. The 26.10mm height fits standard 3.5-inch bays.

Questions about this item

Will this 3.5-inch SATA 6.0Gb/s drive fit in my older four-bay NAS that uses 6.0Gb/s backplanes?

The drive uses the standard 3.5-inch form factor and SATA 6.0Gb/s interface, matching common NAS backplanes and drive bays designed for that size and speed.

How can I confirm the 5400 RPM drive is healthy after installing it in my NAS?

Run the NAS built-in SMART test or Western Digital Data Lifeguard Diagnostics; a pass with zero reallocated sectors and normal spin-up time confirms the 1TB CMR drive is operating correctly.

The box says Bare Drive — what exactly is included and what must I source separately?

Only the 1TB drive itself is included; mounting screws, a SATA data cable, and a SATA power connection must come from your NAS chassis or enclosure kit.
