Silver 2.5 inch SAS hard drive in black Gen14 caddy

DELL

DELL AL15SEB24EPY 2.4TB 10K RPM SAS 2.5" internal hard drive

SKU CH-PTWY-NSQC2

A 2.4TB 10000RPM SAS drive with 512MB cache and a GEN14 tray for compatible PowerEdge servers

  • 4TB capacity stores large enterprise datasets
  • 10000RPM rotational speed accelerates transaction-heavy workloads
  • SAS 6Gb/s interface integrates with compatible PowerEdge servers
  • 512MB cache buffers burst I/O for consistent throughput
  • Includes GEN14 caddy for direct 2.5in bay installation

2.4 TB 10K SAS Drive

This 2.4 TB enterprise hard drive spins at 10000 RPM and uses a 12 Gb/s SAS interface with a 512 MB cache. It is built for Dell PowerEdge servers that require high-throughput block storage in a 2.5 inch form factor. The unit ships new with a Gen14 caddy for direct installation.

SAS 12 Gb/s Interface Limits

The drive connects through a SAS 6Gb/s interface type while the highlighted specification lists 12 Gb/s throughput. Real-world transfer rates will not exceed the slower of the controller, backplane or cable rating in the host system. Cable length and connector quality also constrain sustained bandwidth.

Capacity and Throughput Headroom

The 2.4 TB capacity suits databases, virtualisation hosts and logging workloads that benefit from 10K RPM latency. Sequential throughput scales with the 12 Gb/s link, but random I/O peaks at the mechanical limits of the spindle speed. Workloads needing higher IOPS or lower latency will require solid-state media.

Questions about this item

Should I pick the 2.4TB 10K RPM SAS model or a different capacity for my Dell server?

This drive is a single 2.4TB 10000RPM SAS unit with 512MB cache. Choose it when you need that exact capacity and speed for a supported PowerEdge.

What does the 12Gb/s headline speed deliver inside a compatible PowerEdge?

The drive runs on a 2.5" SAS 6Gb/s interface; the 12Gb/s figure reflects the controller link, so sustained throughput will be limited to the 6Gb/s SAS lane.

Which SAS standard does the AL15SEB24EPY use and what does it cap in practice?

It uses a 2.5" SAS 6Gb/s interface, capping the drive's maximum transfer rate to 6Gb/s regardless of the 12Gb/s controller connection.
