Seagate Exos 1.2TB SAS Drive

This Seagate Exos internal hard drive delivers 1.2TB of storage in a 2.5-inch form factor. It spins at 10000 RPM and connects via a SAS 12GB/s interface. The drive is built for desktop and server environments that require high-speed enterprise storage.

Suited for SAS 12G Systems

This drive fits systems equipped with a SAS 12GB/s controller and a 2.5-inch drive bay. It is not for platforms lacking a SAS host bus adapter or those limited to interfaces other than SAS. Builders needing larger capacity per spindle should consider higher-capacity models.

10000 RPM Rotational Speed

The 10000 RPM spindle speed determines the drive's latency and sustained transfer performance. This specification decides whether the drive meets the IOPS requirements of transactional workloads. Verify that your controller and backplane support the full 12GB/s SAS link to utilise the rated speed.

Questions about this item

Should I pick the 1.2TB Exos 10K SAS model or a larger capacity?

Choose the 1.2TB model when you need 10000 RPM performance in a 2.5" bay and the 1.2TB capacity meets your dataset size; larger capacities exist in the same Exos 10K line if you need more space.

What does the 12G SAS rating mean once the drive is installed in my server?

The 12G SAS interface supports up to 12Gb/s per lane; actual throughput depends on your HBA or backplane, but the drive will not exceed that 12Gb/s link speed.

Does the SAS 12G interface limit the 10000 RPM drive in a 6G backplane?

Yes, a 6G backplane caps the link at 6Gb/s, so the 10000 RPM drive will run at half the interface bandwidth while retaining its rotational speed and latency benefits.
