Dell N85XX 3.84TB SAS 12G RI 2.5" Gen14 drive

This Dell N85XX solid-state drive provides 3.84TB of storage in a 2.5-inch small form factor. It connects through a SAS interface running at 12Gbps and uses MLC memory rated for read-intensive workloads. The drive is built for Dell Gen14 servers and compatible caddies across multiple rack and tower platforms.

Sustained read-intensive workload behaviour

The RI endurance rating means the drive is optimised for workloads dominated by reads, such as data warehousing and analytics. MLC memory supports consistent throughput during extended operations without the write-heavy wear seen in mixed-use drives. The 12Gbps SAS link maintains bandwidth during long sequential scans or concurrent user queries.

Read-intensive endurance rating decides fit

The RI rating is the single specification that determines whether this drive matches the workload. It suits read-heavy applications but is not intended for write-intensive databases, logging or caching tiers that demand higher program-erase cycles. Buyers needing greater write endurance should select a drive with a different endurance class.

Questions about this item

How much heat does the 3.84TB SAS 12G RI 2.5" drive generate during continuous read-intensive workloads?

The drive uses MLC memory optimised for read-intensive workloads, which typically produces less heat than write-heavy SSDs, but exact thermal output depends on your server airflow and workload profile.

Which server backplane or caddy is required to install this 2.5" SAS SSD?

It fits Dell 2.5" drive bays and ships with a compatible caddy for PowerEdge R240, R340, R360, R440, R540, R640, R6415, R740, R740XD, R740XD2, R7415, R7425, R840, R940, R940XA and newer Gen14 models.

Will this 12Gbps SAS SSD work in an older 6Gbps SAS backplane?

Yes, the SAS interface negotiates down to 6Gbps on legacy backplanes, so the drive will function at the slower link speed while retaining its 3.84TB capacity and read-intensive endurance.
