Hi I am wanting to upgrade storage without sacrificing speed and was wondering what are my options. I have 2x 250gb ssd running in RAID 0, I bought 2x 500gb ssd. I know that with RAID 0 when combining all 4 will limit capacity. Do I just clone the 250s to the two 500s and then just either sell the 250s or use them for basic storage? What is my best options here? Thanks.
