Enterprise NAS Storage

The Western Digital WD6005FFBX is a 6TB 3.5-inch internal hard drive built for multi-bay NAS enclosures. It spins at 7200 RPM with a 256MB cache and connects via a SATA 6.0Gb/s interface. The Red Pro series is rated for workloads up to 300TB per year and supports systems with up to 24 drive bays.

Suited For

This drive suits administrators running 24-bay NAS arrays that demand sustained write performance and vibration tolerance. It is not suited for portable externals, laptop upgrades, or any platform that only accepts 2.5-inch form factors or non-SATA interfaces.

Deciding Spec

The SATA 6.0Gb/s interface is the single specification that determines compatibility; the host must provide a standard SATA data and power connection. Only systems with 3.5-inch drive bays and SATA controllers can use this unit.

Questions about this item

Will my NAS chassis accept the 3.5-inch form factor and SATA 6.0Gb/s interface of this WD6005FFBX drive?

Yes, any NAS bay built for 3.5-inch SATA drives will physically and electrically accommodate this model.

Can this 7200 RPM Red Pro drive share a RAID volume with slower 7200 RPM drives already in my NAS?

Mixed RPMs in one RAID array are not recommended; performance will drop to the slowest member.

How do I verify the 256MB cache and 300TB/year workload rating are active after installation?

Check the drive’s SMART attributes and the NAS management console; both report cache size and cumulative workload data.
