Dell 745GC SAS drive

The Dell 745GC is a 300 GB 2.5-inch SAS hard drive spinning at 10000 RPM with a 64 MB buffer. It ships new with a hot-swap tray included and is built for server environments that demand fast, reliable storage.

Suits servers needing 300 GB of 10K SAS storage

This drive fits servers that require a 300 GB 10000 RPM SAS disk with hot-swap capability. Systems that need a different capacity, a different rotational speed or a non-SAS interface cannot use this part.

SAS 6 Gb/s interface

The drive connects through a Serial Attached SCSI interface running at 6 Gb/s, so the host must provide a compatible SAS backplane or controller for the drive to function.

Questions about this item

How do I install the 745GC drive and its hot-swap tray in a 2.5" SAS bay?

Slide the 745GC drive into the supplied hot-swap tray until the SAS connector seats firmly on the backplane, then push the tray into the 2.5" bay until the latch clicks; the step often missed is not fully engaging the latch, which leaves the 6 Gb/s link intermittent.

What maintenance or replacement will the 300 GB 10000 RPM SAS drive need over time?

The 745GC is a mechanical hard drive with a 64 MB buffer; plan to replace it once SMART reallocated-sector counts rise or after the rated annualised workload limit is reached, and keep firmware current via the server management console.

What is the first limit that appears when the 745GC runs sustained workloads in a server?

The 10000 RPM spindle and 6 Gb/s SAS interface cap sustained throughput at the drive's mechanical transfer rate, so latency and queue depth become the bottleneck before the interface saturates.
