Enterprise 2.5" SAS drive
The Seagate Savvio 10K.2 ST9146802SS is a 146GB 2.5-inch laptop hard drive with a SAS 3Gb/s interface spinning at 10000 RPM. It is built for server environments that demand fast mechanical access in a small form factor.
Capacity and headroom
The 146GB capacity suits operating-system volumes, transaction logs or small databases that benefit from low latency rather than bulk storage. Average seek time of 3.8ms and average write time of 4.4ms keep random I/O responsive, but the drive runs out of space quickly for media libraries or large virtual-machine images.
Thermals, noise and power
Enterprise 10000 RPM mechanics generate noticeable heat and audible seek noise under sustained load, so adequate chassis airflow is required. Power draw rises during heavy random workloads, reflecting the spindle speed and SAS signalling, yet remains within typical 2.5-inch enterprise limits for rack or blade installations.

Questions about this item
Will the 146GB 2.5" SAS 3Gb/s drive work in an older server backplane that only supports SAS?
The drive uses a SAS 3Gb/s interface; it will negotiate down to the backplane's supported speed if the controller allows SAS speed negotiation.
How can I verify the ST9146802SS is performing correctly after installation?
Check that the drive reports 10000 RPM, 146GB capacity and SAS 3Gb/s link speed in the RAID controller BIOS or OS disk utility; average seek time should be near 3.8ms.
What comes with the bare-drive ST9146802SS and what must I source separately?
Only the 2.5" hard drive is included; you must supply a 2.5" drive tray or caddy, SAS data and power cables, and a compatible SAS controller or backplane.
