Performance vs. Transfer Size

ATTO is a useful tool for quickly benchmarking performance across various transfer sizes. You can get the complete data set in Bench. Read performance is equivalent to the competitors at all IO sizes, but the maximum write speed is slightly lower compared to the rest of the pack.

    I'm totally not getting the new drop down menus in the consistency part of the review. I only get one set of data points in the chart even though I can select 2 (different) items. It changes whether I change the first or second part. Can someone explain what it shows me when?

    The drop down menus in the consistency part of the review are not working properly. The only way I could make the charts show the performance of the 25% over-provisioning was to choose another SSD from the menu (I chose the A-Data since it is right next to the X300) then change back to the X300. When I did that the chart would update.

    I had to repeat with the default over-provisioning menu to get the chart to change back. This is a pain and needs to be corrected!

    I've noticed that too. Let me see if there is something we can do to fix it -- my HTML skills are limited to copy-pasting so I need to ask someone else to have a look at the code.

    I wonder if encryption would affect deduplication in any kind of setup. As far as I know, repeatable patterns that can be compressed are exactly the thing that encryption prevents, and any deduplication effort must happen before the drive is encrypted. Will encryption ALWAYS be transparent?
