1.2TB 10K SAS drive for servers

The Seagate ST1200MM0158 is a 1.2TB 2.5-inch enterprise hard drive spinning at 10000 RPM with a 128MB cache. It connects through a SAS 12Gb/s interface for high-throughput server and storage-array workloads.

Bare drive 15mm height fits dense bays

Supplied as a bare drive without carrier or cables, the unit measures 15.00mm high, 70.10mm wide and 100.46mm long. The 2.5-inch form factor allows more spindles per rack unit than 3.5-inch alternatives, while the 12Gb/s SAS connector supports dual-port redundancy in compatible backplanes.

TurboBoost and PowerChoice firmware features

Seagate TurboBoost accelerates I/O operations to maintain response times during peak demand. PowerChoice provides T10-compliant power management so administrators can tune consumption. The drive also presents 512e and 4Kn advanced format options for modern operating systems.

商品問答

What does the SAS 12Gb/s interface cap the external transfer rate at?

The SAS 12Gb/s interface caps the external transfer rate at 1200MB/s, which is the maximum sustained throughput the drive can deliver to the host controller.

Will the 15.00mm height fit a standard 2.5-inch server bay?

The drive measures 15.00mm tall, 70.10mm wide and 100.46mm long, so it fits a 2.5-inch bay that accepts 15mm drives; verify the bay height before installing.

How is the bare drive installed and what step is often missed?

Mount the bare drive in a 2.5-inch tray or caddy, connect the SAS data and power cables, then configure the RAID controller or HBA to recognise the new LUN; the step often missed is completing the controller-level initialisation before the OS sees the volume.
