Enterprise storage drive

The DELL 1.2TB 10K SAS 2.5" drive serves PowerEdge servers needing high-speed enterprise storage. It fits 12th generation platforms including T620, R220, R420, R620, R720, R720XD and R820 systems. Administrators handling database or virtualisation workloads gain 10000 RPM performance in a small form factor.

SAS 6Gb/s interface limit

The SAS 6Gb/s link caps sustained throughput at six gigabits per second regardless of spindle speed. Backplanes or controllers limited to 3Gb/s will halve the available bandwidth. The 2.5" SFF form factor restricts use to bays designed for that size; 3.5" slots require an adapter not included.

Simple caddy installation

Installation slides the drive into a compatible hot-plug caddy and seats it in the server bay. The most common issue is a bay or backplane that only supports 3Gb/s SAS, which reduces speed without warning. Firmware mismatches between the drive and the RAID controller can also prevent the array from coming online.

Questions about this item

Should I choose the 1.2TB version or a different capacity?

This drive provides 1.2TB of storage. Verify your server's capacity limits and form factor requirements before selecting.

What does the 10000 RPM rating mean for actual server performance?

The 10000 RPM spindle speed delivers high IOPS and low latency for demanding enterprise workloads on compatible PowerEdge systems.

How does the SAS 6Gb/s interface limit real-world throughput?

The SAS 6Gb/s link caps the maximum theoretical transfer rate at 6Gbps. Actual throughput depends on your controller and system configuration.
