Hi, i have two Western Digital RED 8TB (WD80EFZX). I need to buy other two disk and build a software RAID5 with the others. Now, the WD80EFZX serie have been replaced by WD80EFAX (Western Digital RED 8TB). I use a LSI-92118i in ITmode and I will setup the raid using mdadm. Do I have problem if two disks of four are of the same brand, the same size, both RED, but different model?
