6 TB SAS enterprise drive

The Seagate Exos 7E8 ST6000NM029A is a 6 TB 3.5-inch internal hard drive built for nearline storage workloads. It spins at 7200 RPM with a 256 MB cache and connects through a SAS 12 Gb/s interface. The bare-drive packaging suits system integrators and server deployments.

Suits arrays needing dual-port SAS connectivity

This drive fits storage arrays, backup appliances and RAID enclosures that require dual-port SAS 12 Gb/s links and 7200 RPM throughput. It is not for platforms that lack a SAS controller or backplane, nor for laptops or small-form-factor bays limited to 2.5-inch devices. Buyers who need hot-plug trays or carrier-specific firmware should verify compatibility before purchase.

SAS 12 Gb/s interface decides fit

The single specification that determines whether this is the right part is the SAS 12 Gb/s interface. The drive will only operate in systems equipped with a compatible SAS HBA, RAID controller or expander that supports 12 Gb/s signalling. Without that host connection the drive cannot be used.

Questions about this item

What does the 7200 RPM speed mean for actual throughput in a server?

The 7200 RPM spindle delivers sustained sequential performance suited to bulk storage and nearline workloads in a server chassis.

What does the SAS 12Gb/s interface cap at in real use?

The SAS 12Gb/s link tops out at 12 Gbit/s per port; actual throughput depends on the controller and workload mix.

Will this 3.5 inch drive fit a standard hot-swap bay?

The 3.5 inch form factor matches standard enterprise drive bays and backplanes for direct mounting.
