I've recently been doing some research in preparation for building myself a fileserver for my home network. My goal is to have a RAID 6 array with between 5 and 8 drives and I am currently in the process of trying to decide which hard drives are the best bang for my buck. In doing this research however, I have come across some people who suggest that using Western Digital reds in RAID arrays greater than 5 disks will either not work at all or will have a severe performance decrease as a result of the firmware on them. I'm wondering if anyone else is aware of any problems like this or has knowledge in this area. Your thoughts are appreciated!
