Seagate NAS and WD Red HDD DAS RAID Performance Analysis

By: Paul Alcorn | HDDs in IT/Datacenter | Posted: Jan 20, 2014 9:31 pm

RAID 0 128K Sequential Read/Write




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.




The mixed read/write performance tests reveal that the WD Red fares better from 70-100% write, while the Seagate NAS HDD array performs best with heavy read workloads.
