WD Black 1TB desktop hard drive

The WD Black WD1003FZEX is a 3.5-inch internal hard drive built for desktop PCs that need high sustained throughput. It spins at 7200 RPM with a 64 MB DRAM cache and connects through a SATA 6.0 Gb/s interface. The drive is aimed at creative professionals, gamers and system builders who work with large media files or game libraries.

Best for heavy workloads not portable use

This drive suits users who want maximum mechanical performance inside a full-size tower for tasks such as video editing, photo archives or game installs. It is not designed for laptop bays, external enclosures or scenarios that demand silent operation or solid-state latency. Builders needing a 2.5-inch form factor or an all-flash array should look elsewhere.

SATA 6.0 Gb/s interface decides compatibility

The single specification that determines fit is the SATA 6.0 Gb/s host interface combined with the 3.5-inch 26.10 mm height. Your motherboard must provide a standard SATA data port and power connector, and the case must accept a 147.00 mm long drive. If the system only offers M.2 slots or a smaller drive bay, this unit will not install.
