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.
