Enterprise SAS Drive
The Seagate Savvio 15K.2 ST9146852SS is a 146GB 2.5-inch internal hard drive spinning at 15000 RPM with a 16MB cache. It uses a SAS 6Gb/s dual-port interface and is supplied as a bare drive. The physical dimensions are 3.95" x 2.76" x 0.57". This unit is designed for enterprise server environments requiring high rotational speed.
Server Workload Suitability
This drive suits administrators deploying high-IOPS storage in compatible 2.5-inch SAS bays. The 15000 RPM spindle speed and low average latency support transaction-heavy applications. Buyers needing more capacity per spindle or drives for non-SAS backplanes should look at other options. Systems without SAS host bus adapters cannot use this drive.
SAS 6Gb/s Interface
The dual-port SAS 6Gb/s connection is the single specification that determines compatibility. It requires a controller or backplane supporting this exact interface standard. Verify that your server or storage array accepts 2.5-inch SAS drives before purchase. The 6Gb/s link speed defines the maximum data throughput available.

Questions about this item
How much heat and noise does the 15000 RPM Savvio 15K.2 produce when running continuously in a server?
The drive spins at 15000 RPM with a 2ms average latency; enterprise 2.5" 15K drives typically draw more power and generate more heat than slower laptop drives, so ensure your chassis has adequate airflow.
What controller or backplane do I need to connect the SAS 6Gb/s interface?
You need a SAS host bus adapter or RAID controller that supports 6Gb/s SAS; the drive uses a standard SAS connector and will not function on interfaces other than SAS.
Will the 2.5" 146GB drive fit in the same bay as my older 2.5" SAS drives?
Yes, it shares the 2.5" form factor measuring 100.45 x 70.10 x 14.50 mm, matching the industry-standard 2.5" drive bay used by previous-generation SAS drives.
