Enterprise SAS drive
The Seagate ST1200MM0009 is a 1.2TB 2.5-inch SAS hard drive spinning at 10000RPM with a 12Gb/s interface and 128MB cache. It is built for servers and storage arrays that need consistent random-access performance in a small form factor. The 512n sector format ensures broad compatibility with legacy and current RAID controllers.
Capacity and headroom
At 1.2TB the drive holds operating-system volumes, databases or virtual-machine images that benefit from low latency. The 10000RPM spindle and 12Gb/s link keep queue depths short under typical OLTP workloads. Sequential throughput will saturate well before the interface limit, so very large streaming jobs run out of spindle speed first.
Thermals noise and power
The 2.5-inch helium-free chassis runs within standard enterprise temperature limits when installed in a ventilated bay with adequate airflow. Acoustic output is typical for a 10K SAS drive and is masked by chassis fans in a rack. Power draw stays within the 12Gb/s SAS specification during sustained reads and writes.

Questions about this item
Will the 12Gb/s SAS interface on this 2.5in drive work with my existing 6Gb/s SAS controller?
Yes, the 12Gb/s SAS interface is backward compatible with 6Gb/s and 3Gb/s SAS controllers, though the drive will operate at the controller's maximum supported speed.
How can I verify the ST1200MM0009 is running at its full 10000RPM after installation?
Use SMART monitoring tools such as smartctl or the controller BIOS to confirm the reported rotational speed shows 10000RPM and that the negotiated link rate reads 12Gb/s.
Does the 1.2TB SAS drive ship with a mounting bracket or cables, or must I source them separately?
The drive is supplied as a bare 2.5in unit; any 2.5in-to-3.5in adapter brackets and SAS data or power cables must be purchased separately.
