Looking at trying consumer SSDs as an alternative to HDDs on hardware raid. But the raid controller seems to fill the entire disk when the raid is created (at least from the viewpoint of the disk) it uses many hours for creating an array. So it seems to me that from the disks point of view it is full. SSDs don’t like being full, can this cause trouble? If so what is the alternative? Storage spaces? (I use windows for other reasons). I know storages spaces have really weak write rates with parity (or used to have), don’t know if this works better with SSDs?
Look into if your controller support TRIM, if it does, make sure it is enabled and you are good to go. (If it doesn’t you are correct that you shouldn’t use ssds with it)
