DELL 400-ANFK 4TB 3.5" SAS 12Gb/s 7200 RPM internal hard drive

Dell 400-ANFK 4TB Nearline SAS Drive

The Dell 400-ANFK is a 4TB 3.5-inch internal hard drive built for nearline workloads. It spins at 7200 RPM and connects through a SAS interface rated at 12Gb/s. The drive ships as a bare unit with a hot-swap tray for quick installation in compatible bays. Dell part number 400-ANFK identifies the original equipment specification.

Suited for arrays needing high-capacity SAS storage

This drive fits servers and storage arrays that accept 3.5-inch SAS devices and benefit from 4TB of nearline capacity. The 7.2K spindle speed supports sequential throughput for bulk data, backups and archiving. It is not the right choice for buyers who want the low latency of solid-state media, for systems that only provide SAS 3Gb/s ports, or for environments where a 2.5-inch form factor is required.

12Gb/s SAS interface decides compatibility

The single specification that determines fit is the 12Gb/s SAS interface. A backplane or controller limited to 3Gb/s will restrict the drive to that lower transfer rate. Verify that the host system supports 12Gb/s SAS and provides a 3.5-inch hot-swap bay before purchase.
