Enterprise SAS Drive

This HGST Ultrastar 15K147 drive delivers 74GB of storage on a Serial Attached SCSI interface. It spins at 15000 RPM with a 16MB cache for high transaction rates. The 3.5 inch form factor fits standard server bays. A mature design aims to reduce qualification time.

Suited For High IOPS Workloads

Database servers and storage arrays that prioritise low latency over raw capacity will benefit from the 3.6ms seek time and 2ms average latency. The SAS interface supports dual-port redundancy for enterprise enclosures. Buyers who need larger capacities or a different interface should consider other options.

15000 RPM Spindle Speed

The 15000 RPM rotation speed is the single specification that determines whether this drive meets the performance envelope of a 15K enterprise tier. It drives the quoted seek and latency figures for random I/O intensive applications. Verify that the host system provides a compatible SAS backplane and power budget.

Questions about this item

Does the bare-drive package include cables, brackets or mounting screws for a 3.5" SAS bay?

The drive ships as a bare unit only; SAS data cable, power cable and any 3.5" mounting hardware must be sourced separately.

Is the 74 GB, 15 000 RPM Ultrastar 15K147 the only capacity and speed offered in this model?

Yes, this MPN is a single 74 GB capacity running at 15 000 RPM with 16 MB cache; no other capacities or speeds exist for HUS151473VLS300.

What does the 3.6 ms average seek time mean for real-world database workloads on a SAS controller?

The 3.6 ms seek and 2 ms latency give very low access delay, so random I/O-heavy database tasks see consistently fast response on a SAS host bus adapter.
