The 128K sequential speeds reflect the maximum sequential throughput of the HDD, using a file size encountered in normal NAS usage.

 

The WD Red array averages a tremendous 537 MB/s average, while the Seagate NAS HDD array averages 398 MB/s.

The Seagate NAS HDD leads with an average of 616MB/s, while the WD Red trails with 555 MB/s. The Seagate NAS HDD has an extra burst of speed that kicks in when it detects sustained sequential read activity, which provides a clear advantage in sequential workloads.
