Specifications and Feature Set Comparison

Prior to getting into the performance evaluation, we will take a look at the specifications of the 6 TB Seagate Enterprise NAS HDD and see how it compares against the other NAS-specific hard drives that we have looked at before. As mentioned in our launch coverage, the Enterprise NAS HDD takes the hardware guts from the Enterprise Capacity v4 drives and firmware features from the NAS HDD line. The hardware aspects (such as the rotational speed, cache size, URE ratings etc.) come from the Enterprise Capacity v4. The table below presents the data for the drive against the others in our evaluation database.

A high level overview of the various supported SATA features is provided by HD Tune Pro.

We get a better idea of the supported features using FinalWire's AIDA64 system report. The table below summarizes the extra information generated by AIDA64 (that is not already provided by HD Tune Pro).
