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 Corsair P256 did great in Sandra 2009 SP3 and was found to have an average read score of 222.499MB/s with a write score of 186.541MB/s. Notice the random access time at both read and write is just 1ms.
Comparison Chart: When comparing the Corsair P256 to other popular hard drives like the Western Digital Scorpio Blue 500GB and the Seagate Momentus 7200.3 320 GB, it does better than any of the other drives tested. It should be noted that the random access time for the write test on the Super Talent MasterDrive SSD was 109ms, which is a red flag. The Corsair P256 SSD had an access time of just 1ms, so the Samsung controller seems to be much better than a JMicron controller as that s what the Super Talent SSD uses. Look at the difference between the write performance on the two SSDs in the chart above. The Corsair P256 SSD is very fast!
