Enterprise NAS drive

The WD Red Pro WD240KFGX is a 24TB 3.5-inch hard drive built for 24x7 operation in multi-bay commercial and enterprise NAS enclosures. It uses conventional magnetic recording and a 7200 RPM spindle to sustain heavy multi-user workloads. ||

SATA 6.0Gb/s interface

The drive connects through a standard SATA 6.0Gb/s port, making it compatible with NAS appliances and servers that use this interface. Systems limited to SATA 3.0Gb/s will operate at the lower link speed. ||

24TB capacity with 300TB yearly workload

The 24TB capacity and 512MB cache comfortably absorb sustained write streams in RAID arrays rated for up to 24 bays. The 300TB per year workload rating marks the boundary beyond which endurance and error-rate targets are no longer guaranteed.

Soalan tentang produk ini

How does the 7200 RPM speed affect real-world throughput in a NAS?

The 7200 RPM spindle speed combined with a 512MB cache helps sustain high sequential transfer rates for large files and improves random I/O response during multi-user access.

What practical limit does the SATA 6.0Gb/s interface place on this 24TB drive?

The SATA 6.0Gb/s link caps the maximum burst transfer rate at 6.0Gb/s, so sustained reads and writes will not exceed the interface bandwidth even though the drive holds 24TB.

Will the 26.10mm height fit a standard 3.5" drive bay or hot-swap tray?

Yes, the 26.10mm height matches the standard 3.5" form factor, so it fits typical NAS bays, server backplanes and desktop cages without adapters.
