The Momentus XT is a 7200 rpm low power Laptop SSHD (Solid State Hard Drive). The XT is one of the early SSHD models and at nearly four years of age it's now over the hill and struggles to keep up with newer drives. With peak sequential speeds in the region of 100 MB/s the Momentus is approximately 70% slower than the current group leaders. Most SSHDs offer relatively good small file 4K read and write performance but that isn't the case for the Momentus XT which only averages 0.6 MB/s in the random 4K tests. There are far better alternatives currently available for the same money. [Jan '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.
