The 2TB version of WD's Red NAS range of hard drives has a performance profile that is similar to that of its larger 3TB sibling. Both drives lag behind the group average significantly in terms of overall performance. With an average read speed of 108 MB/s the 2TB Red is 36% slower than the group leaders which manage an average of 147 MB/s. There is a huge amount of hype around the "NAS" aspects of these drives but there is very little substance in terms of specific characteristics that make this drive better suited to a NAS than any other. The obvious factors such as energy efficiency and operating temperature are only marginally improved on these drives. I would personally prefer one of the far better performing Seagate Barracudas as when looking at a direct comparison of the Barracuda vs the Red it's clear that the performance of the Barracuda is better across the board. [Feb '14 HDrivePro]

The new 3TB Seagate Barracuda 2016 (ST3000DM008) replaces its hugely successful predecessor, the 3TB Barracuda 7200.14 2011 (ST3000DM001). Comparing performance between the two models shows that the newer drive has 12% faster sequential speeds, comparable 4K speeds, improved mixed sequential speed and reduced mixed 4K speed. Overall, the effective speed is 12% faster on the 2016 model. Since there is normally little price difference between the two models the 2016 version is the clear winner especially for use as a backup drive with its impressive sequential read and write speeds of nearly 200 MBps.
