I currently have an SSD boot drive and a RAID 0 array of 2x1TB HDDs for data in my Mac Pro (plus a separate 2TB HDD for Time Machine). The SSD is getting a bit small (80GB Intel X25-m!) now that I put my Lightroom catalog on it. I was wondering about fusing the SSD and the RAID 0 array in a home-made fusion drive. Would that work?
