WD Greens are mainly used as secondary storage solutions. They offer great capacity to store massive data and also run quiet and cool which makes them pretty reliable for backup solutions as well. http://www.wdc.com/en/products/products.aspx?id=830
WD Red drives are identified as NAS drives because they are specifically designed and tested for 1-8 bay NAS systems and PCs with RAID configurations. In other words - optimal performance for systems operating in NAS and RAID environments. http://www.wdc.com/en/products/products.aspx?id=810
