WD Gold 12 TB 3.5 in SATA Internal HDD
This WD Gold hard drive provides 12 TB of storage in a standard 3.5 inch form factor. It connects via a SATA interface and spins at 7200 RPM with a 256 MB cache. The drive is built for internal installation in compatible desktop or server systems.
Suited for high-capacity bulk storage on SATA
This drive fits users who need large-capacity mechanical storage on a SATA 6 Gb/s connection. It is not suitable for systems that lack a 3.5 inch drive bay or a SATA data and power connection. Buyers who require a smaller physical format or a different interface should consider other options.
12 TB capacity decides fit for mass data workloads
The single specification that determines suitability is the 12 TB capacity. This volume targets archival, surveillance or bulk data workloads where total terabytes matter more than access speed. Verify that your host system supports drives of this capacity before purchase.

Questions about this item
Should I pick the 12 TB model or a smaller capacity?
The 12 TB version gives the most space per drive bay; choose a lower capacity only if your workload does not need that volume.
What does 7200 RPM mean for daily use?
It keeps read and write heads moving at 7200 revolutions per minute, so large sequential files and multi-user workloads stay responsive.
Will the SATA 6 Gb/s interface run at full speed on my motherboard?
It negotiates down to SATA II 3 Gb/s on older ports, capping sustained throughput at roughly half the rated 6 Gb/s.
