NAS-focused 3 TB CMR drive

The WD Red Plus WD30EFRX is a 3.5 inch hard drive built for home and small office NAS enclosures. It uses conventional magnetic recording and a SATA 6.0Gb/s interface to deliver 3 TB of storage in a 24x7 environment. The firmware is tuned for multi-bay compatibility and continuous operation.

Sustained 180 TB per year workload

NASware firmware manages error recovery and power balance during long write sessions typical of RAID rebuilds or backup jobs. The 5400 RPM class motor and 64 MB cache maintain a typical host transfer rate of 145 MB/s without the thermal spikes seen in desktop drives. Workload rating reaches 180 TB per year.

Low power draw and standard mounting

Read and write power sits at 4.4 watts while standby drops to 0.6 watt, reducing heat in crowded chassis. The 26.10 mm height fits any standard 3.5 inch bay using common SATA data and power connectors. Systems older than Windows Vista or OS X 10.4 may require partitioning to recognise the full capacity.

商品問答

How much heat and power does the 3 TB WD Red Plus produce when running 24×7 in a NAS?

The drive draws 4.4 watts during read and write activity and 0.6 watt in standby, keeping heat output low for continuous operation.

What host interface and bay count does the WD30EFRX require to work in my enclosure?

It connects via a SATA 6.0 Gb/s port and is validated for systems with up to 8 drive bays.

Will this 5400 RPM CMR drive work reliably alongside older SATA drives in the same NAS?

Yes — NASware firmware and the 180 TB/yr workload rating are designed for mixed-drive 24×7 environments.
