Dell 3.84 TB SAS SSD for servers

This Dell 4NMJF is a 3.84 TB enterprise solid-state drive built for read-intensive workloads. It connects through a 12 Gb/s SAS interface in a standard 2.5 inch form factor. The drive targets servers and storage arrays that prioritise consistent read throughput and endurance over mixed-write performance.

Straightforward 2.5 inch SAS installation

The drive slides into any 2.5 inch hot-swap bay or caddy wired for SAS 12 Gb/s. No extra cables or adapters are required beyond the backplane connection. The most common issue is placing the drive in a SATA-only backplane, which will prevent the 12 Gb/s link from negotiating.

Suits read-heavy arrays, not write-heavy logs

This SSD suits database replicas, content-delivery nodes and analytics volumes where reads dominate. It is not suited for write-heavy workloads such as transaction logs, high-frequency checkpointing or sustained mixed I/O that demand higher write endurance. Buyers needing greater write durability should consider a mixed-use or write-intensive model.

Questions about this item

How can I verify the 12Gb/s SAS link is active after installing the 4NMJF drive?

Check the host controller BIOS or management utility; it should report a negotiated 12Gb/s SAS link for the 4NMJF device.

What ships with the 4NMJF 3.84TB drive and what must I source separately?

The 4NMJF 2.5" SSD ships alone; a compatible SAS backplane, cables, and any mounting bracket are not included.

Which capacity of the 4NMJF read-intensive SAS SSD should I choose for a write-light database?

The 4NMJF is offered in a single 3.84TB capacity, suited to read-heavy workloads such as reporting databases.
