Thank you all. That's what i've thought but better stay safe than sorry so i've asked. In other words WD Red SSD are safe for a RAID, there is no need to change them (as mostly new) in both array (the grow was finished 1 hour ago: 2 WD Gold SATA 3.5 plus 1 WD RED SSD) Slowly, i'll replace all spinning disks with WD Red SSD I'm not a fan of WD, but 2TB disks able to replace a 2TB HDD are very very rare (the 1.92TB, much more common, can't replace a 2TB disk)
