I invite you to please read this report.
NAND Flash is good for a lot of things but not naturally good with write-intensive workloads. Unless, that is, skillful engineering is involved to mitigate the intrinsic weaknesses of NAND Flash in this regard. I assert EMC XtremIO architecture fills this bill.
Regardless of your current or future plans for adopting non-mechanical storage I hope this lab report will show some science behind how to determine suitability for non-mechanical storage–and NAND Flash specifically–where Oracle Database redo logging is concerned.
Please note: Not all lab tests are aimed at achieving maximum theoretical limits in all categories. This particular lab testing required sequestering precious lab gear for a 104 hour sustained test.
The goal of the testing was not to show limits but, quite to the contrary, to show a specific lack of limits in the area of Oracle Database redo logging. For a more general performance-focused paper please download this paper (click here). With that caveat aside, please see the following link for the redo logging related lab report:
