Western Digital WD Black WD6002FZWX 6TB 7200 RPM 128MB SATA 3.5" internal hard drive

Desktop performance hard drive

The Western Digital WD Black WD6002FZWX is a 6TB 3.5" internal hard drive built for desktop PCs. It spins at 7200 RPM with a 128MB DRAM cache and connects via a SATA 6.0Gb/s interface. The drive targets creative professionals, gamers and system builders who need high-capacity storage for demanding workloads.

Suited for high-capacity desktop builds

This drive fits users who prioritise large storage space and sustained throughput for media libraries, project files or game installs. It is not suited for builders whose systems only accept 2.5" drives or M.2 form factors, nor for those who need the lower latency of solid-state storage. The 26.10mm height requires a standard 3.5" bay with adequate clearance.

128MB DRAM cache on the 6TB model

The 6TB capacity is the only model in this series that provides 2X DRAM cache up to 128MB, which accelerates read operations for heavy multi-tasking. This cache size is the key specification that distinguishes the 6TB variant from lower-capacity versions and determines whether the drive matches a workload that benefits from a larger buffer.
