Enterprise SAS SSD for Dell PowerEdge

The K74WN-CP1 is a 960 GB SAS solid-state drive built for Dell PowerEdge servers. It uses a 12 Gbps interface and TLC NAND optimised for read-intensive workloads. The 2.5 inch form factor fits standard hot-plug bays across a wide range of rack, tower and modular chassis.

Practical limits of the 12 Gbps SAS interface

A 12 Gbps SAS link caps sustained throughput at the bus level, so sequential speeds cannot exceed that ceiling regardless of NAND performance. The drive is rated for read-intensive duty, meaning write endurance is lower than mixed-use or write-intensive models. Workloads with heavy random writes will hit the endurance boundary sooner.

Build quality and connector implications

Enterprise-grade firmware is updated and components are tested before shipment, ensuring consistent behaviour in multi-drive arrays. The SAS connector supports dual-port operation for path redundancy in compatible backplanes. Hot-plug capability allows replacement without powering down the server, reducing service disruption.

Questions about this item

Which capacity should I choose for a read-intensive workload?

The 960GB model is the only capacity offered for this PM1643a drive, designed for read-intensive enterprise use.

What does the 12Gbps SAS link mean for real-world throughput?

The 12Gbps SAS interface supports up to 12Gbps per lane, with actual throughput limited by the controller and backplane in your PowerEdge server.

Will this 2.5-inch SAS SSD work in my R740 server?

Yes, the K74WN-CP1 is validated for the R740 and the full list of PowerEdge models including R640, R750, R750XA, and MX740C.
