I have a 250GB Samsung 850 EVO that I put in my personal laptop back in May. I also have a 250GB Samsung 850 EVO that I just put in my desktop a couple weeks ago. I'm thinking about wiping both, and using both in my desktop for a RAID 0 configuration since I don't use my laptop at school anymore (I had only put an SSD in it for faster load times so I could make sure I was up and running fast enough to take notes).

My question is this: is it safe to use two used and differently aged (albeit identical) SSDs of different ages to run a RAID 0 configuration, or is it necessary to use two new identical SSDs? Do you think I'll run into stability and reliability issues?
