Single Client Access - DAS Benchmarks

The drives under test were connected to a 6 Gbps SATA port off the PCH in our DAS testbed. After formatting in NTFS, they were subject to our DAS test suite. The results are presented in the graphs below.

It appears that the extra cache in the Seagate Constellation ES.3 and Enterprise Capacity v4 do help in robocopy benchmarks.

We also used PC Mark 8's storage bench suite to record the bandwidth numbers for selected workloads including Adobe Photoshop, After Effects and Illustrator.

    old article i never seen issues with data reliability unless the drive itself has been problematic (bits of the disk that cant be read and the stupid drive not remapping it) norm i just change the drive once issues happen or random issues as i had with some samsung drives not liking my server (fine in other systems)

    thank you for the test. I just want to buy some used SAS drivers from https://www.servershop24.de/ . With your suggestions I can decide which is the best for me.
