This drive can be used as a combined system and storage drive thanks to its fast 7200K rpm and enormous 3TB capacity. Recently prices for all large drives have been dropping and the 3TB Barracuda 7200.14 is currently a good choice in terms of both value for money and performance. Not only does the Barracuda have respectable sequential read/write speeds but it also goes head to head with the various green options, consuming a very reasonable 5.4W vs 5W (idle) on average for a "green" drive. That amounts to a tiny power consumption disadvantage and a lot more speed. Overall the Barracuda is priced aggressively and represents very good value for money. [Oct '12 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.
