Seagate Cheetah 10K.6 147GB SCSI Drive

The Seagate Cheetah 10K.6 ST3146807LC is a 147GB 3.5-inch internal hard drive spinning at 10000 RPM with an 8MB cache. It uses a SCSI Ultra320 80-pin interface and is supplied as a bare drive. Average seek time is 4.7ms, average write time is 5.3ms, and average latency is 2.99ms.

Who This Suits and Who It Does Not

This drive suits maintainers of legacy servers or storage arrays that require a SCSI Ultra320 80-pin connection and a 3.5-inch form factor. Buyers who need larger capacities or newer interface standards should look elsewhere.

The Deciding Specification

The SCSI Ultra320 80-pin interface is the single specification that determines compatibility; the drive will only function in systems equipped with a matching controller and backplane.

Questions about this item

How is the 80-pin SCSI Ultra320 drive installed in a 3.5" bay and what step is often missed?

Mount the bare drive in a 3.5" bay, connect the 80-pin SCA connector to a hot-swap backplane or 68-pin adapter, then set a unique SCSI ID via the jumpers before powering on.

What maintenance or replacement will the ST3146807LC need later?

The 10 000 RPM mechanical assembly and bearings are the primary wear items; plan to replace the drive once SMART reallocated-sector counts rise or seek times exceed the 4.7 ms / 5.3 ms specs.

What limit appears first during sustained workloads on this Cheetah 10K.6?

The 8 MB cache fills quickly under heavy random I/O, so average latency settles at the 2.99 ms rotational limit before the Ultra320 bus saturates.
