High-capacity enterprise hard drive

This 18TB 3.5-inch drive spins at 7200 RPM and connects through a SATA 6.0Gb/s interface with 256MB cache. It is built for cloud data centres, NAS deployments and large-scale RAID arrays where sustained throughput and density matter.

Suited for bulk storage workloads.

The drive targets hyperscale archives, backup targets and distributed file systems such as Hadoop and Ceph. It is not for workloads that demand sub-millisecond access times or all-flash performance.

18TB capacity in a 3.5-inch form factor

The single specification that decides fit is the 18TB capacity delivered in a standard 3.5-inch chassis. If the storage plan calls for less capacity or a 2.5-inch bay, a different drive is required.
