Enterprise storage drive

The Cisco UCS-HD300G10K12G= is a 300GB internal hard drive built for servers and storage arrays that need consistent throughput. Its SAS 12Gb/s interface and 10000 RPM spindle suit transactional databases, virtualisation hosts and other latency-sensitive workloads.

Thermals and power

A 2.5 inch form factor keeps the drive’s thermal footprint small inside dense chassis, while the 10000 RPM motor draws predictable power under sustained read and write loads. Acoustic output remains low enough for rack environments where multiple drives operate side by side.

Included accessories

The drive ships in retail or OEM packaging that may vary, so no mounting brackets, cables or management software are guaranteed in the box. Installers should plan for standard SAS backplane or HBA connectivity and any required carrier trays separately.

Questions about this item

How do I install this 2.5" SAS 12Gb/s drive in a Cisco UCS server and what step is often missed?

Slide the 2.5" drive into the hot-swap bay until the SAS 12Gb/s connector seats firmly; the step often missed is engaging the bay lever fully so the drive locks and the activity LED registers.

What maintenance or replacement will this 10000 RPM 300GB drive need later?

No scheduled maintenance is required; the 10000 RPM mechanical mechanism will eventually wear, so plan to replace the 300GB drive when SMART alerts or performance drops appear.

What limit appears first on this SAS 12Gb/s drive under sustained heavy writes?

The 10000 RPM spindle speed caps sustained write throughput, so the mechanical transfer rate becomes the bottleneck before the SAS 12Gb/s interface saturates.
