Dell 500 GB SAS laptop drive

This Dell 342-0428 is a 500 GB 2.5" internal hard drive with a SAS 6Gb/s interface. It spins at 7200 RPM and provides 16 MB cache for server workloads. The drive is supplied new and includes a tray for direct installation. It targets administrators expanding storage in compatible Dell PowerEdge systems.

Verify SAS controller and tray fit

Confirm that your server or workstation has an available SAS 6Gb/s backplane or controller before ordering. The 2.5" form factor requires a matching drive bay and the supplied tray must match your chassis generation. Check the system service manual for supported drive models and firmware requirements.

Adds hot-plug capacity to arrays

Installed in a hot-plug bay the drive expands RAID arrays without downtime and draws power from the backplane. The 7200 RPM spindle delivers 8.5 ms average seek and 9.5 ms average write latency for mixed read-write workloads. No separate cabling or mounting hardware is needed beyond the included tray.
