Enterprise 146 GB 15K SAS drive

The Seagate Savvio 15K.2 ST9146852SS is a 146 GB hard drive spinning at 15000 RPM with a 6 Gbps SAS interface and 16 MB cache. Its 2.5 inch form factor fits mainstream servers, storage arrays and space-constrained data centres. The self-encrypting drive feature adds hardware-based data protection. It is sold as a bare drive only.

Installation and common issues

The drive uses a standard SAS connector and slides into any 2.5 inch hot-swap bay or caddy without extra tools. Most problems arise when the backplane or controller does not support 6 Gbps SAS speeds or lacks SED key management, causing the drive to negotiate down or remain locked. Firmware mismatches between the drive and the RAID controller can also prevent the array from initialising.

Compatibility checks before ordering

Verify that your server or array accepts 2.5 inch SAS drives and that the controller firmware lists the ST9146852SS as supported. Confirm the backplane provides 6 Gbps SAS lanes and that your encryption key management system can provision the SED feature if you plan to use it. Ensure the operating system includes a SAS driver capable of 15000 RPM devices.

Pitanja o ovom artiklu

How can I verify the ST9146852SS is running at 15000 RPM after installation?

Check the drive's reported rotational speed in your RAID controller BIOS or operating system utilities; it should show 15000 RPM. The SAS 6Gb/s link speed will also be confirmed during the controller's device discovery process.

What is included with this bare drive and what must I source separately?

The shipment contains only the 2.5-inch SAS hard drive itself. You must separately provide a compatible SAS backplane or cable, a 2.5-inch drive bay or adapter, and a RAID controller or HBA with a 6Gb/s SAS port.

This model is listed as 146GB and 146.8GB — which capacity should I expect?

The formatted capacity is 146 GB (146.8 GB unformatted). Plan your array using the 146 GB figure; the 16 MB cache and 15000 RPM performance apply to this single capacity version.
