Hello Yes you can build a raid0 or stripe with this two disk. I think the maximum speed for the stripe or raid0 is the speed of the slowest disk. But I think is not a good idea, In storage system we cannot build raid or stripe with disk with different speed.
Just remember with stripe or raid0 there is no data protection, if one of your disk in the raid0 is broken you lost all data. For the other question I don't know.
