10 TB WD Red Pro 3.5" SATA hard drive

This 10 TB Western Digital drive spins at 7200 RPM and provides 256 MB cache over a SATA interface. It is built for multi-bay NAS enclosures and rated for a 550 TB yearly workload. The 3.5 inch form factor suits standard drive bays in rack or tower units.

Suited for 24-bay NAS arrays

Designed for 24x7 operation in systems with up to 24 bays, it handles high-intensity multi-user access and file-system rebuilds on platforms such as ZFS. Buyers needing a drive for a single-bay desktop enclosure or a portable USB device should look at something else.

550 TB per year workload rating decides fit

The 550 TB annualised workload rating at 40 °C is the key figure that determines whether this drive matches your NAS duty cycle. If your environment exceeds that rate, a different drive class is required.

Questions about this item

How much heat and noise does the 7200 RPM 3.5" drive produce during continuous 24x7 operation?

The drive is rated for typical operation at 40C with a 550TB per year workload limit, indicating it is built for sustained multi-user NAS duty.

Which NAS enclosures or host interfaces are required to use this SATA 6 Gb/s CMR drive?

It connects via standard SATA and is tested for compatibility with most NAS enclosures, supporting systems up to 24 bays.

Will the 256 MB cache and 7200 RPM speed work properly with older SATA 3 Gb/s backplanes?

The SATA interface is backward compatible, so the drive will operate on older 3 Gb/s ports at the slower link speed.
