Seagate 750GB Momentus XT Solid State Hybrid Hard Drive Review
Seagate 750GB Momentus XT Solid State Hybrid Hard Drive Review - PCSTATS
Looking no different than any common 2.5" notebook hard drive, the trick up the Momentus XT's sleeve that it learns what data you frequently use and caches this to its 8GB of internal flash memory.

HDD Benchmarks: SiSoft Sandra Read / Write

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.

The 750GB Seagate Momentus XT SATA III SSHD achieves a good write index of 148.84 MB/s in Sandra, a fair margin faster than the 1st Gen. drive which operates on the SATA II interface. Curiously, write random access time is a hair slower (9.65ms vs 7ms) on the new 750GB Momentus XT compared to its predecessor.
