Enterprise 14TB SATA drive

The Western Digital WD142KRYZ is a 14TB 3.5-inch internal hard drive built for enterprise storage systems. It spins at 7200 RPM with a 512MB cache on a SATA 6.0Gb/s interface. The Gold series design targets 2.5M hours MTBF for continuous operation in data centres and RAID arrays.

Suited for bulk storage, not speed-critical tiers

This drive fits servers, NAS units and backup appliances that need high capacity and sustained throughput. Buyers who want low-latency random access for databases or virtual machines should look at solid-state alternatives. It is also not intended for portable or laptop installations due to its 3.5-inch form factor.

14TB capacity on SATA 6.0Gb/s

The single specification that decides fit is the 14TB capacity delivered through a SATA 6.0Gb/s connection. Verify that your controller and backplane support this capacity and interface before purchase.

Spurningar um þessa vöru

How does the 7200 RPM speed affect sustained throughput during long write sessions?

The 7200 RPM spindle and 512 MB cache maintain high sequential transfer rates across the full 14 TB capacity, so sustained writes stay near the SATA 6.0 Gb/s interface limit without the slowdown seen on slower spindles.

What noise and heat levels should I expect when this drive runs continuously in a server chassis?

Designed for enterprise storage systems, the 3.5 inch form factor dissipates heat through the chassis airflow while acoustic output remains within data-centre specifications for 24/7 operation.

Which host controller and cabling do I need to install this SATA 6.0 Gb/s drive?

A standard SATA 6.0 Gb/s port on the motherboard or RAID card, a matching SATA data cable, and a 12 V / 5 V power connector from the PSU are all that is required.
