The WD 18TB Gold 7200 rpm SATA III 3.5" Internal Datacenter HDD is a high-capacity storage drive designed for use in servers and storage arrays. It has a SATA III 6 Gb/s interface, 256MB cache, and a 7200 rpm rotational speed that allows for a sustained rate of up to 255 MB/s. The WD 18TB Gold 7200 rpm SATA III 3.5" Internal Datacenter HDD uses HelioSeal Helium technology, which reduces power consumption by up to 26% compared to standard drives. It has an error tolerance of <1 in 1015, MTBF of 2.5 million hours, and an AFR of 0.35%, making it a reliable option for small- to medium-scale enterprise environments. Additionally, Western Digital offers 24/7 premium support and includes Acronis True Image WD Edition cloning software.

Workload Capability

Delivering both performance and reliability to any datacenter environment, WD Gold hard drives are designed to handle workloads up to 550TB per year.

Reliability

With a MTBF of up to 2.5 million hours, WD Gold hard drives deliver reliability and durability for yearly operation (24x7x365) within demanding storage environments.

Disk Utilities and Migration Tools

Acronis True Image WD Edition can clone drives as well as backup your operating system, applications, settings, and all of your data, while also having the ability to wipe any data you no longer need securely. You can quickly and easily deploy a new hard drive to your PC or laptop and automatically migrate your operating system, applications, and all of your important data.

RAID-Specific, Time-Limited Error Recovery (TLER)

Reduces the drive's fallout caused by the extended hard drive error-recovery processes common to desktop drives.

Extended Thermal Burn-in Test

Each drive is put through extended burn-in testing with thermal cycling to ensure reliable operation.

Dynamic Fly Height and Dual Actuators

A head positioning system with two actuators that improves positional accuracy over the data track. The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy.
