The exceptional performance of vSAS among such a broad array of test configurations accentuates the
consistent superiority of the SAS interface compared to SATA. Furthermore, SAS speeds are forecasted to
improve over time with a technology roadmap spanning throughout the next decade. Conversely, the SATA-IO
(Serial ATA International Organization) has announced on multiple occasions that they have no plans to extend
SATA bandwidth beyond the current 6Gbps rate. The SAS interface is also known to be more reliable and
robust. At the other end of the scale, NVMe outperforms vSAS, but its higher price warrants it to be primarily
used when peak performance is required.
In Conclusion
Toshiba Memory Corporation markets their value SAS SSD to enable a “life after SATA” and, so long as pricing
remains competitive across all storage capacities, their campaign seems very fitting. All three PowerEdge
configurations tested prove that value SAS SSDs deliver significant performance gains when compared to SATA
SSDs, while also retaining the more reliable and robust SAS protocol. These transparent benefits should
encourage users looking to optimize their workload performance to consider the advantages of replacing SATA
SSDs with the innovative value SAS SSD.
