Capacity and interface

The Dell 400-AQJN is an 8TB 3.5-inch internal hard drive with a SAS 12Gb/s interface spinning at 7200 RPM. It is built for servers and storage arrays that need high-capacity nearline storage in a hot-swap tray.

SAS throughput ceiling

The 12Gb/s SAS link sets the maximum bus transfer rate, but sustained throughput will be limited by the 7.2K rotational speed and mechanical latency. Workloads demanding consistent low-latency IOPS or sequential speeds beyond the drive’s physical limits will hit this bottleneck.

Hot-swap installation notes

The drive ships as a bare unit designed for hot-swap bays, so no tools are required if the chassis supports 3.5-inch SAS trays. Common issues arise when the backplane or controller does not recognise the Dell part number, or when the SAS connector is not fully seated during a live insertion.

Questions sur cet article

Should I choose the 8TB 7200 RPM version or a lower-capacity model?

The 8TB 7200 RPM drive gives the maximum capacity and spindle speed in this part number; a smaller model would reduce both storage space and sustained throughput.

What does the 12Gb/s SAS rating deliver in a live server?

The 12Gb/s SAS interface supports up to 12 gigabits per second of host bandwidth, so real-world throughput is limited by the 7200 RPM mechanics and the controller, not the link.

Which SAS standard does the 400-AQJN use and what speed ceiling does it impose?

It uses 12Gb/s SAS, capping the host link at 12 gigabits per second while the 7200 RPM platters determine actual sustained transfer rates.
