Sometimes that's a good idea, sometimes it might make things worse. A previous server that had a RAID-1 of SSDs was limited by SSD write speed. As the SSDs got old the write speed dropped significantly. If I had 2 servers that each had the same brand of SSDs then one server would need both SSDs replaced while if I had 2 servers with different brands then each server would need a single SSD replaced which would have been more hassle.
