Dell 400-AMPP 8TB Nearline SAS Drive

The Dell 400-AMPP is an 8TB 3.5-inch Nearline SAS hard drive spinning at 7200 RPM. It is built for servers and storage arrays that need high-capacity bulk storage with hot-swap capability. The bare-drive packaging suits system integrators and IT departments replacing or expanding existing drive bays.

12Gb/s SAS Interface Practical Limits

The drive connects through a 12Gb/s SAS interface while the specifications also list a 3Gb/s average latency figure. Actual throughput will depend on the host controller and backplane negotiated link speed. Cable length, expander topology and concurrent drive count can reduce sustained transfer rates below the interface maximum.

Compatibility Checks Before Ordering

Verify that your chassis accepts 3.5-inch hot-swap trays and that the backplane supports SAS signalling at the required link rate. Confirm the RAID or HBA controller recognises Nearline SAS drives and presents the correct block size. Ensure firmware revisions on both controller and drive are aligned for reliable operation.

Questions about this item

Should I choose the 8TB model or a smaller capacity for my storage array?

The drive is offered in an 8TB capacity; select it when you need that amount of raw space in a single 3.5" bay.

What does the 7.2K RPM rating mean for everyday read and write speeds?

At 7200 RPM the drive delivers nearline performance suited to bulk storage and sequential workloads rather than low-latency transactional work.

The SAS interface is listed at 12Gb/s — what throughput can I expect in practice?

The 12Gb/s SAS link sets the bus ceiling; actual sustained transfer will be limited by the 7200 RPM mechanical speed and the 3Gb/s average latency figure.
