CrystalDiskMark tests read and write performance with incompressible data using different random block sizes and sequentially. With read speeds the Adrenaline cache solution are just as fast, if not faster than many of the standalone SSDs. Like with AS-SSD, its 4k read speeds with high queue depths are untouchable. Write speeds fall back down below the performance level of the standalone SSDs, but 4K writes are about 75x faster with the Adrenaline compared to the bare hard drive.
FutureMark's PCMark 7 Pro has a useful storage benchmark. It tests read and write patterns of commonly used functions that computer users will encounter regularly. While most of the other tests show the raw performance of the drives, PCMark helps to translate that performance into how it will affect daily functions. The Adrenaline caching solution fared very well in the benchmark. It performed similar to the standalone Crucial m4 drive, and only fell behind in one of the subtests. While we know from the other two benchmarks that the read speed of the Adrenaline is very fast and the write speed is much slower, it's clear through PCMark 7 that most user tasks rely heavily on read operations.
