For a "typical" simulation, if that even exists, the solver itself should not do much disk I/O at all. During a transient simulation, you probably want to write some results to disk periodically.

Thank you so i understand a write intensive might be better choice than read intensive?

Judging by the terminology, I guess you are currently looking at data center SSDs?
read/write intensive is mostly used to distinguish between different drives within a product line. The specification that mostly determines this label is "drive writes per day", along with write performance of course. It is highly unlikely that you will exceed the write endurance of even a read intensive data center SSD, provided you pick one with decent storage capacity.
That being said, I would recommend you look at the actual specifications, instead of a rather vague label. And in case you pick a consumer SSD, maybe have a look at a review to make sure the SSD can handle at least some sustained writes. Which brings me back to my original recommendation: Samsung 970 Evo Plus. You can't go wrong with that.
