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.

Questions about this item
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.
