18 TB Enterprise Hard Drive for Servers
The Seagate Generation 11 drive delivers 18 TB of storage on a 3.5 inch SATA 6.0 Gb/s interface. It spins at 7200 RPM with a 256 MB cache and uses CMR recording technology. The helium-sealed design is rated for 24/7 operation in enterprise NAS, DAS, workstation and data centre environments.
Helium-Sealed Build with Hot-Swap Tray
A helium-sealed enclosure reduces internal friction and supports continuous duty cycles. The drive ships installed in an HP Gen11 3.5 inch tray that fits Gen10+ and Gen11 ProLiant servers, enabling hot-swap replacement without powering down the chassis. SATA connectors follow the standard 6.0 Gb/s pin-out for direct backplane attachment.
Verify SATA Backplane and Tray Clearance
Confirm that your server or storage array accepts 3.5 inch SATA drives and provides a compatible Gen10+ or Gen11 hot-swap bay. The included tray is required for proper alignment in listed ProLiant DL and ML models. Systems without a matching backplane or tray will not support this drive.

Questions about this item
What real-world throughput does the SATA 6.0 Gb/s interface deliver on this 18 TB drive?
The SATA 6.0 Gb/s link supports a sustained data transfer rate up to 270 MB/s on this 18 TB model.
Does the 3.5-inch form factor require a specific tray for HP Gen11 servers?
It ships pre-installed in a 3.5-inch HP Gen11 tray that also fits Gen10+ and Gen11 ProLiant servers.
How is the drive installed in a hot-swap bay and what step is often missed?
Slide the tray into the bay until the latch clicks; the step often missed is fully seating the latch to engage the hot-swap connector.
