I've heard that if you have two drives with different capacity, you will be limited to the slower one when making a RAID-0 configuration. The drives that I would combine however, seem to have the same read & write specs. It's a Samsung 850 Pro SSD. The one I have is 512 GB and the one I would buy would be 1 TB. According to this site… http://www.anandtech.com/show/8216/samsung-ssd-850-pro-128gb-256gb-1tb-review-enter-the-3d-era … they both have the same read & write specs. What do you think? Is it okay to create a RAID-0 config with them?
