What about the performance on writting?SDDs are different. They may differ drastically in terms of speeds in different use patterns.
What about the lifecycle of SSDs that are quite less than HDDs? I've heard from the vender that its about 6 years.lifecycle of SSDs is not measured in time. It is measured in writes.

I'm running oracle 18.104.22.168.0 on windows environment.
We need to change our server that has began too old to attend our needs
We're planning to run a SSD raid 5 for improve performance.
I think it is hard to predict whether the self-tuning aspects of Oracle will handle these oddly fast devices appropriately, and if there are issues there, there could be some lag time before enough people complain that Oracle deals with it. Of course, they may be way ahead of me there, they aren't going to be completely reactive with a new version coming out, perhaps the developers got to play with new toys.Just for information. Oracle offers whole line of flash storage devices, from SSDs to Flash Array.
