I discovered that in IRST there is an option to set a cache mode for my 3 ssd raid 0 array. I've read the documentation by Intel and have some questions:

Are there any overall benefits/risks from enabling cache mode?
As I'm on a laptop, would write back be recommended? I read it increases chance of data loss on power interruption. What is the difference between how windows handles data integrity and the intel driver?
Read only mode seems to have the benefit of faster reads, does it have any downsides?

Thanks for your help guys!
