Enterprise SAS SSD 3.84 TB

This Dell 400-ATHS drive is a 3.84 TB internal solid-state drive with a 2.5-inch form factor and a SAS interface operating at 12 Gbps. It uses MLC flash with a 512n sector format and is built for enterprise servers and storage arrays that require high-capacity, high-reliability flash storage. The component is supplied new and is intended for installation in compatible 2.5-inch drive bays.

Not for consumer PCs

The drive targets IT professionals managing Dell PowerEdge servers or similar enterprise platforms that support 12 Gbps SAS backplanes. It suits workloads needing consistent read-heavy performance and endurance from MLC media. Buyers without a SAS controller or hot-plug backplane cannot use this drive. Systems limited to consumer drive interfaces will not accept this part.

SAS 12 Gbps interface decides fit

The single specification that determines compatibility is the 12 Gbps SAS interface. The host system must provide a SAS HBA, RAID controller, or backplane that supports this signalling rate and the 2.5-inch SFF form factor. Without a matching SAS connection the drive will not function, regardless of capacity or flash type.

  • 84 TB capacity stores large datasets
  • 12 Gbps SAS interface enables fast data transfer
  • 5 inch form factor fits standard drive bays

Questions about this item

Does the server backplane need a 12 Gbps SAS controller to use this 3.84 TB drive?

Yes, the drive connects through a 12 Gbps SAS interface, so the host controller or backplane must support that speed for full performance.

Will this 2.5" SAS SSD work in a caddy designed for 3.5" mechanical drives?

A 2.5" to 3.5" adapter bracket is required; the drive itself uses the standard 2.5" SFF form factor.

How can I confirm the 512n sector format is recognised after installation?

Check the operating system disk utility or RAID controller BIOS — it should report 512-byte native sectors for the 3.84 TB volume.
