  • 12 Gbps SAS interface moves data quickly
  • Read-intensive TLC suits heavy read workloads
  • 5 inch form factor fits standard bays
  • Compatible with Dell PowerEdge servers

960 GB SAS enterprise SSD

This 960 GB SAS solid-state drive uses read-intensive TLC NAND for server workloads that favour consistent read throughput. It fits 2.5-inch hot-plug bays in compatible Dell PowerEdge platforms. The PM1633a firmware has been updated and each unit is tested before dispatch.

12 Gbps interface thermal profile

The SAS 12 Gbps link keeps data moving without saturating the backplane during sustained reads. Read-intensive tuning limits write amplification, which helps maintain steady temperatures inside dense chassis. Power draw scales with queue depth rather than peaking on burst activity.

Dell PowerEdge compatibility list

The drive is validated for a wide range of PowerEdge rack, tower and modular servers including R630, R740, R750, MX740c and MX750C lines. It also supports MD1400 and MD1420 storage arrays. No extra carrier or adapter is required for the listed systems.

Questions about this item

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

Slide the drive into a hot-plug bay until the carrier clicks, then verify the controller sees the 12Gbps link; the step often missed is confirming the backplane negotiates 12Gbps instead of falling back to 6Gbps.

What maintenance or replacement will the PM1633a read-intensive TLC drive need over its service life?

As a read-intensive TLC device it has a lower write endurance budget, so plan to replace the drive once the media wears to the rated endurance limit or if SMART attributes report reallocated sectors.

What limit appears first when the 960GB SSD runs sustained workloads in a 12Gbps SAS environment?

The 12Gbps SAS interface bandwidth ceiling is reached before the internal TLC media saturates, making the link the first bottleneck during continuous sequential transfers.
