Seagate Momentus XT 750 GB Hybrid HDD Review

On the sequential read and write test, the two Seagate Momentus XT hybrid drives exhibited the worst performance in both the read and write tests. However, the second-generation Momentus XT was 17% faster for read and 19% faster for write than the first-generation Momentus XT, proving that the second-generation drive is faster than its previous version even if the hybrid technology isn’t used.

As you can see, the two regular hard drives included, the Seagate Momentus 750 GB and the Western Digital Scorpio Black 750 GB, beat the two Seagate hybrid drives. The Seagate Momentus 750 GB was 7% faster for read and 10% for write than the new second-generation Momentus XT 750 GB, while the Western Digital Scorpio Black 750 GB was 14% faster for read and 14% faster for write.

The OCZ Agility 3 SSD 240 GB achieved the best level of performance, beating the second-generation Seagate Momentus XT 750 GB by 94% and the first-generation Seagate Momentus XT 500 GB by 128% in the read test and beating the second-generation Seagate Momentus XT 750 GB by 104% and the first-generation Seagate Momentus XT 500 GB by 142 percent.

The second-generation Momentus XT 750 GB was 65% faster than the first-generation Momentus XT 500 GB.
