Capacity and interface

This is a Dell 342-2340 3TB 7200 RPM SAS 3.5" internal hard drive supplied as a bare drive. It uses a Serial Attached SCSI interface rated at 12Gb/s average latency and a 6Gb/s transfer rate. The 3.5-inch form factor fits standard server drive bays and the hot-swap tray design allows replacement without powering down the chassis.

Server storage suitability

The drive is built for nearline server workloads where consistent 7200 RPM performance and SAS connectivity are required. It suits administrators expanding capacity in compatible Dell PowerEdge or equivalent SAS-equipped arrays. It is not for systems without a SAS host bus adapter or backplane, nor for environments that demand solid-state latency or higher spindle speeds.

Deciding specification

The single specification that decides fit is the SAS interface combined with the 6Gb/s transfer rate; the host system must provide a matching SAS controller and backplane to recognise and use the drive.

Questions about this item

What type of controller or backplane does the 342-2340 need to operate?

The 342-2340 requires a SAS backplane or host bus adapter that supports 6 Gb/s SAS for the drive to be recognised and function.

Will the 342-2340 work in a system that only has 3 Gb/s SAS ports?

Yes, the 342-2340 is backwards compatible with 3 Gb/s SAS infrastructure; it will operate at the lower 3 Gb/s link speed.

How can I confirm the 342-2340 is running at its full 7200 RPM after installation?

Check the drive’s reported rotational speed in the RAID controller BIOS or operating system disk utility; it should show 7200 RPM.
