WD Gold 16TB Enterprise SATA HDD

The Western Digital WD161KRYZ is a new 16TB 3.5-inch internal hard drive built for enterprise storage systems. It spins at 7200 RPM and uses a SATA 6.0Gb/s interface with a 512MB cache to handle demanding workloads. The Gold series is rated for up to 2.5M hours MTBF and includes vibration protection for multi-drive environments.

Suited for servers and arrays needing

This drive fits administrators filling rackmount chassis or NAS units where sustained write performance and endurance matter. It is not for builders who need the low latency of solid-state storage or the compact M.2 form factor for space-constrained laptops. Buyers wanting portable external backup should also consider a different form factor.

SATA 6.0Gb/s interface

Your backplane or controller must support the SATA 6.0Gb/s standard and accept a 26.10mm high, 101.60mm wide, 147.00mm long drive bay. Verify these physical and electrical requirements before purchase.
