Enterprise 15K SAS Drive

The HGST Ultrastar 15K147 is a 36.7GB 3.5-inch internal hard drive spinning at 15000 RPM with a 16MB cache and a Serial Attached SCSI interface. It is built for servers and storage arrays that demand low-latency access to small, transaction-heavy datasets.

Suited For High-IOPS Workloads

This drive suits administrators who need 3.3ms average seek time and 2ms latency for database logging, tiered caching or legacy application compatibility. Buyers who need more capacity per spindle, larger cache buffers or a different physical interface should look elsewhere.

SAS Interface Determines Compatibility

The drive connects only through a Serial Attached SCSI port, so the host system must provide a compatible SAS backplane or controller. Without that specific interface the drive cannot be installed or used.

Questions about this item

What type of host bus adapter or controller is needed for the SAS interface on this 3.5" drive?

A Serial Attached SCSI host bus adapter or RAID controller with a compatible SAS port is required for the 15000 RPM Ultrastar 15K147 drive.

Can this 15000 RPM SAS drive share a backplane with older 3.5" drives that use a different interface?

The HUS151436VLS300 uses a SAS interface; mixing it with drives using other interfaces on the same backplane requires a controller or backplane that supports both protocols simultaneously.

How can I verify the 3.3ms average seek time and 2ms average latency are being met after installation?

Run a benchmark tool that reports seek and latency metrics and compare the results to the 3.3ms seek and 2ms latency specifications for the 36.7GB model.
