SiSoft Sandra 2011 - HDD Read and Write tests	Source: Sandra

Sandra is designed to test the theoretical power of a complete system as well as the individual components. The results are also purely theoretical and may not represent real world performance. Higher points are better.

When it comes to read performance the 750GB Seagate Momentus XT SSHD does not disappoint with a result of 91.39MB/s! This synthetic test does not take advantage at all of the Momentus XT's Adaptive Memory, which is why there is such a large discrepancy between the SSHD and SSD read performance. Random Access Time is 15ms, a couple seconds quicker than the 1st gen. Momentus XT was able to attain.
