Enterprise 10K SAS Drive

The Seagate ST1200MM0139 is a 1.2 TB enterprise hard drive built for 2.5 inch drive bays. It spins at 10000 RPM and connects through a SAS 12Gb/s interface with a 256 MB buffer. This combination targets workloads that demand consistent throughput and low latency.

Suited for Transaction-Heavy Arrays

This drive suits database servers, virtualisation hosts and high-performance storage arrays that can exploit 10000 RPM spindle speed and SAS connectivity. Buyers who need capacities beyond 1.2 TB or who require a different physical form factor should evaluate alternative models.

Deciding Specification: SAS 12Gb/s Interface

The SAS 12Gb/s interface is the single specification that determines compatibility; the system backplane or controller must support this exact standard. Without a matching SAS 12Gb/s host connection the drive cannot operate at its rated performance.

Perguntas sobre este artigo

Does the 2.5-inch form factor and 0.6-inch height fit a standard 2.5-inch drive bay?

The drive measures 2.5 inches wide, 4 inches deep and 0.6 inches high, matching the standard 2.5-inch internal bay dimensions.

How is the SAS 12Gb/s interface connected, and what is the common mistake?

Connect the SAS data and power cable to the drive's SAS port; the frequent error is not fully seating the connector until it clicks.

When will the 256 MB buffer or 10000 RPM mechanism need replacement?

Enterprise drives of this class are rated for continuous operation; replace the unit if SMART attributes report reallocated sectors or excessive seek errors.
