Capacity and Interface

This 18TB 3.5-inch internal hard drive uses a SATA 6.0Gb/s interface and spins at 7200 RPM. It is built with helium-sealed CMR technology and a 512MB cache for sustained throughput in enterprise environments.

Who This Suits

System builders deploying HP ProLiant Generation 11 servers or compatible DAS and NAS enclosures will find the factory-installed Gen11 tray and Power Disable Pin 3 support simplify installation. Buyers needing a different physical interface or a non-enterprise firmware load should look at other drive classes.

Deciding Specification

The sustained data transfer rate reaches up to 269 MB/s, a figure that determines whether the drive can meet the throughput demands of backup, archiving and big-data analytics workloads.

Questions about this item

Does this 3.5-inch drive fit a standard desktop drive bay?

Yes, the 3.5-inch form factor matches standard desktop and server bays. It ships installed in a Western Digital/HP Gen11 tray that is compatible with Gen10+ and Gen11 ProLiant servers.

How do I install the drive, and what step is often missed?

Slide the tray into the hot-swap bay until it clicks, then secure the latch. The step often missed is enabling the SATA port in BIOS so the 18TB volume appears to the operating system.

What maintenance will this helium-sealed drive need over its life?

No internal maintenance is required because the helium-sealed enclosure is closed for life. Keep firmware current using the vendor utility and monitor SMART attributes for reallocated sectors or temperature spikes.
