Capacity and interface
The Western Digital WD141KFGX is a 14TB 3.5-inch internal hard drive that connects through a SATA 6.0Gb/s interface. It spins at 7200 RPM and includes a 512MB cache to handle sustained workloads in multi-bay enclosures.
Suited for multi-bay NAS.
This drive is built for enterprise NAS systems that support up to 24 bays and workloads of 300TB per year. Buyers who need a drive for a laptop, a single-bay desktop or workloads demanding SSD-class random performance should look at a different storage class.
300TB annual workload rating
The manufacturer specifies a 300TB per year workload rate, which is the key figure for deciding whether the drive matches the write intensity of the target NAS environment.
