Ultrastar 15K147 73 GB SCSI drive

The HGST Ultrastar 15K147 HUS151473VL3800 is a 3.5-inch internal hard drive with 73 GB capacity and a 15000 RPM spindle speed. It uses an Ultra320 SCSI interface and includes a 16 MB cache buffer. The drive is hot-swappable and comes with a five-year limited warranty.

Suited for legacy enterprise arrays.

This drive fits servers and storage arrays that still operate on parallel SCSI buses and require 15K RPM performance for transaction-heavy workloads. It is not for systems lacking a 3.5-inch Ultra320 SCSI backplane or controller, nor for users who need higher capacity per spindle or a modern serial interface.

Ultra320 SCSI interface decides compatibility

The single specification that determines fit is the Ultra320 SCSI interface; the host must provide a matching parallel SCSI channel and power. Without that bus the drive cannot be installed or used.

Questions about this item

Will this 3.5" 1" high drive fit my server bay?

The Ultrastar 15K147 measures 4" wide, 5.8" deep and 1" high, matching the standard 3.5" form factor used in most enterprise bays.

Which SCSI ID jumper block must be set before inserting the HUS151473VL3800?

Configure the SCSI ID on the rear jumper block before sliding the drive into the hot-swap carrier; the drive is hot-swappable but the ID must be fixed first.

How often should the 16 MB cache bearings be relubricated on a 15000 RPM unit?

The sealed bearing assembly requires no relubrication; plan replacement after the 5-year design life or when SMART reallocated-sector counts rise.
