With peak sequential read/write speeds of 140 and averages of 120 MB/s the 3TB WD Red is around 25% slower than the group leaders. If the Red is used in a NAS (Network Attached Storage), that won't make much difference because the vast majority of home networks still operate at Fast Ethernet (~10 MB/s), even users with faster Gigabit (~100 MB/s) networks will be limited by their network bandwidth before the drive. I could assume that any of our drives are for use in a NAS but that of course doesn't excuse sub-par performance because they could equally be used in a desktop. It's true that the power consumption (4.4W) on the Red is lower than average (6W) but the performance hit isn't justified. Even assuming continuous usage, those extra couple of watts for something like the Seagate Baracuda 7200.14 amount to a few pounds a year at most. At £133 this dive is both overpriced and offers sub-optimal performance. [Feb '14 HDrivePro]

This should only be used in a NAS, its strong points are low operating temperature and power consumption, quiet operation and longevity. On the downside it's not particularly performant under heavy IO loads.
