Enterprise 8TB SAS drive
The Seagate Exos 7E10 ST8000NM018B is an 8TB 3.5-inch internal hard drive built for enterprise bulk-data workloads. It spins at 7200 RPM with a 256MB cache and connects via a SAS 12Gb/s interface. The drive is rated for 550TB of data written per year and a 2 million hour MTBF.
Suited for 24x7 arrays, not desktop PCs
This drive targets data-centre architects and IT teams running replicated or RAID storage that operates around the clock. It is not intended for single-drive desktop use, gaming rigs, or systems that lack a SAS controller and backplane.
Verify SAS controller and bay clearance
Confirm your host bus adapter or RAID card supports SAS 12Gb/s and the 512e/4Kn sector format. Ensure the 3.5-inch bay accommodates the 26.11mm height, 101.85mm width and 147.00mm length. Check that your firmware and cabling match the SAS specification.

Pytania dotyczące tego produktu
What controller or backplane do I need to connect the SAS 12Gb/s interface on this ST8000NM018B?
You need a SAS 12Gb/s HBA, RAID controller or backplane with compatible SAS ports and cables.
Will the 512e/4KN sector format on this 8TB drive work with my older RAID controller that only supports 512n?
The drive uses 512e/4KN formatting; compatibility depends on whether your controller explicitly supports 512e or 4KN logical sectors.
How can I confirm the 7200 RPM spindle speed and 256MB cache are active after installation?
Check the drive's reported RPM and cache size in your OS disk utility or controller BIOS; they should show 7200 RPM and 256MB.
