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.

商品問答

How do I install the 400-ANFK 3.5" SAS drive in a hot-swap bay and what step is often missed?

Slide the drive into the bay until the SAS connector seats fully, then lock the carrier latch; the step most people miss is securing the latch, which leaves the drive loose and prevents the 12 Gb/s link from initialising.

What maintenance or replacement will the 7200 RPM 4TB SAS drive need later?

Plan to replace the drive once its rated workload or SMART thresholds indicate wear; no field-serviceable parts exist inside the sealed 3.5" helium enclosure.

What limit appears first on the 400-ANFK under sustained 12 Gb/s writes?

The 7.2 K RPM mechanical latency caps sustained throughput before the 12 Gb/s SAS interface saturates.
