SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information & diagnostic utility. Sandra provides most of the information (including undocumented) you need to know about your hardware, software and other devices whether hardware or software. In order to test the hard drive SiSoftware Sandra 2009 SP3 was used as part of the test suite. The graphical results that Sandra gives you after the test is completed nicely shows how drives perform over time and where on the drive the performance is seen.
READ Performance Testing:
WRITE Performance Testing:
Benchmark Results: The OCZ Vertex 120GB SSD did great in Sandra 2009 SP3 and was found to have an average read score of 241.894MB/s with a write score of 188.311MB/s. Both read and write access times were just 1ms.
Comparison Chart: When comparing the OCZ Vertex 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 has the same access times that the Corsair P256 SSD offers, but has faster read and write performance.
