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]
