SAS can do 150 IOPs comfortably - and you'll normally be buying smaller drives, because performance is somewhat more interesting to you - so that IOPs/TB number is more relevant. Nov 21, 2018 · “As per Dell. The benefit of running SAS if the prices are comparable are worth it as SAS drives are made for enterprise environments so the HDD are rated to last longer and have a higher MTBF rating. I'm hesitant about sata interfaces in a server, but I want to rep the benefits of the speed of SSDs. More importantly, the SAS roadmap continues to evolve to support the even higher performance expectations of tomorrow’s data center. 5" 7200 RPM SATA drives The fastest SATA SSDs are 6 Gbit/s.
