3.84 TB SAS enterprise SSD for Dell PowerEdge

This 3.84 TB solid-state drive uses a 12 Gbps SAS interface and read-intensive TLC NAND. It is built for Dell PowerEdge platforms including R640, R740XD, R750 and MX740c where high-capacity, low-latency storage is required. The 2.5 inch form factor fits standard hot-plug bays across the listed models.

Thermals noise and power in typical server workloads

Enterprise SAS SSDs of this class draw modest power during read-intensive duties and rely on chassis airflow rather than an onboard fan. In a populated PowerEdge enclosure the drive runs within normal operating temperatures without adding audible noise. Power consumption scales with queue depth but remains consistent with other 12 Gbps SAS TLC devices.

Firmware updates and Dell certification simplify

Each unit ships with updated firmware validated for the compatible PowerEdge and PowerVault systems listed above. The Dell part number CRNPH aligns with the PM1643a controller, so the drive is recognised immediately by iDRAC and OpenManage tools. No extra cables, brackets or licence keys are needed for installation in supported servers.

Questions about this item

How do I install the 2.5-inch SAS drive in a Dell PowerEdge R740 and what step is often missed?

Slide the drive into a hot-swap bay until the carrier clicks, then verify the SAS backplane detects it at 12Gbps in the iDRAC storage view before initializing the volume.

What maintenance or replacement will the PM1643a read-intensive TLC SSD need later?

Monitor SMART attribute 230 for media wear; when it approaches the rated endurance limit, plan a drive swap during a maintenance window to avoid unplanned downtime.

What limit appears first on the CRNPH during sustained sequential reads?

The 12Gbps SAS link saturates before the internal TLC flash, capping throughput at the interface maximum for long-duration workloads.
