Dell 342-5879 4TB SAS Hard Drive

The Dell 342-5879 is a 4TB 3.5-inch internal hard drive built for server environments. It uses a SAS interface running at 6Gb/s and spins at 7200 RPM. The drive includes a hot-swap tray and features secure encryption for data protection. It is supplied as a bare drive in original Dell packaging.

Suited for servers needing encrypted SAS storage

This drive fits servers that accept 3.5-inch SAS drives with hot-swap bays. It is designed for secure workloads requiring hardware encryption. Systems without SAS backplane support or 3.5-inch drive bays cannot use this drive. Buyers needing a different capacity or interface should consider other options.

6Gb/s SAS interface determines compatibility

The drive connects via a 6Gb/s SAS interface, which is the single specification that decides fitment. Only controllers and backplanes supporting this standard can operate the drive. Verify your server documentation for SAS 6Gb/s support before purchasing.

Questions about this item

What does the 6 Gb/s SAS interface cap in practice?

The 6 Gb/s SAS interface limits the maximum burst transfer rate to the bus speed of the controller.

What physical space and tray does the 3.5" drive need to fit?

It requires a standard 3.5-inch drive bay and uses the included hot-swap tray for mounting in compatible Dell servers.

How is the drive installed and what step is often missed?

Insert the drive into the supplied hot-swap tray, then slide the assembly into the server bay until the latch clicks to engage the SAS connector.
