I am dipping my toes in the waters of RAID, looking to purchase hardware to run a RAID 5 or 6. The RED drives are at a tempting price point. I am wondering why it is that they are advertised at only working in an array of 1-5 disks. I have been looking at the QNAP TS-x69 enclosures, either a 6 bay or 8 bay for future expansion. Is there no way that the RED drives can be used in these larger arrays?
