Enterprise 6 TB SAS drive

The Seagate Exos 7E8 ST6000NM029A is a 6 TB 3.5-inch internal hard drive built for 24 x 7 enterprise storage. It spins at 7200 RPM with a 256 MB cache and connects through a dual-port SAS 12Gb/s interface. Conventional magnetic recording and T10 DIF protect data integrity in RAID arrays.

Suited for RAID arrays not for portable use

This drive suits servers and storage arrays that require dual-port SAS connectivity, CMR reliability and advanced write caching for continuous operation. It is not for buyers who need a 2.5-inch form factor, a single-port interface or a lower power profile for mobile enclosures.

Dual-port SAS 12Gb/s interface

The dual-port SAS 12Gb/s connection is the single specification that decides compatibility; the host backplane or controller must support dual-port SAS at 12 Gb/s to use this drive.

Questions about this item

What controller or backplane do I need for the SAS 12Gb/s interface on this Exos 7E8 drive?

The drive connects via SAS 12Gb/s and requires a compatible SAS controller or backplane that supports the 12Gb/s link speed and dual-port operation.

Will the 3.5-inch, 26mm-high form factor fit in my existing server chassis and drive trays?

The drive measures 147mm long, 102mm wide and 26mm high, matching the standard 3.5-inch enterprise form factor used in most server bays and hot-swap trays.

How can I verify the drive is operating correctly after installation?

Check that the system sees the full 6TB capacity at 7200 RPM with 256MB cache, confirm the SAS link negotiates at 12Gb/s, and monitor SMART attributes for reallocated sectors and temperature within spec.
