We really like PCMark 7's Secondary Storage benchmark module for its pseudo real-world application measurement approach to testing. PCMark 7 offers a trace-based measurement of system response times under various scripted workloads of traditional client / desktop system operation. From simple application start-up performance, to data streaming from a drive in a game engine, and video editing with Windows Movie Maker, we feel more comfortable that these tests reasonably illustrate the performance profile of SSDs in an end-user / consumer PC usage model, more so than a purely synthetic transfer test.
PCMark 7's individual tests show the Intel SSD DC S3500 performing just a hair behind the more expensive DC S3700-series drive in 4 of 7 tests. And in the other 3, the Intel SSD DC S3500 just squeaks past the S3700.
With such competitive numbers in the individual tests, the Intel SSD DC S3500's overall score of 5405--which is only 11 points behind the S3700--should be no surprise.
