72.8GB 10K RPM Ultra320 SCSI Drive

This HP 404709-001 is a 3.5-inch internal hard drive with an 80-pin SCSI Ultra320 interface. It spins at 10000 RPM and offers 72.8GB of capacity for legacy enterprise servers and storage arrays. The 1.0-inch height and hot-swap tray allow direct insertion into compatible drive bays. Average seek time is 4.9ms for rapid data access.

Suits maintainers of older SCSI systems

IT teams keeping Ultra320 SCSI infrastructure running will find this drive a direct fit for replacement or capacity expansion. The 80-pin connector and hot-plug tray match original HP Qualified Option specifications. Buyers building new systems or needing larger storage volumes should look elsewhere. Modern interfaces and higher-capacity drives are not supported by this form factor.

SCSI Ultra320 80-pin interface

The single specification that decides compatibility is the SCSI Ultra320 80-pin interface combined with the 1.0-inch hot-swap tray. Only servers and enclosures designed for this exact connector and physical height will accept the drive. Verify the host controller and backplane support Ultra320 signalling before purchase. No adapter or converter is included with the unit.

Questions about this item

Should I choose the 72.8GB 10000 RPM model or a larger capacity at a lower speed?

The 72.8GB 10000 RPM drive delivers the fastest access times in this series. Choose it when transaction speed matters more than raw capacity.

What does the 4.9ms average seek time mean for my server workload?

A 4.9ms seek time means the heads reach data quickly, giving low latency for random I/O workloads such as databases or email stores.

Does the SCSI Ultra320 interface actually deliver 320 MB/s in my system?

The Ultra320 bus caps at 320 MB/s, but sustained throughput depends on the drive's 10000 RPM mechanics and your controller's implementation.
