READ Performance Testing:
WRITE Performance Testing:
Benchmark Results: The OCZ Vertex EX 120GB SSD did great in Sandra 2009 SP3 and was found to have an average read score of 236.691MB/s with a write score of 214.656MB/s. Both read and write access times were just 1ms.
Comparison Chart: When comparing the OCZ Vertex EX to other popular hard drives like the Western Digital Scorpio Blue 500GB and the Seagate Momentus 7200.3 320 GB, it does roughly 3x better than these ‘old school’ platter drives. The OCZ Vertex EX came in third place for the average read test, but was the winner by a long shot when it came to the overall average write times.
