CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.
The SATA6 Testing was done using OCZ Vertex 3 120GB SATA6 SSD drive.
Benchmark Results: The ASUS Maximus IV Extreme-Z was slightly faster than the ASUS Maximus IV Gene-Z in CrystalDiskMark. The Sequential read of the Maximus IV Extreme-Z was an impressive 517.1MB/s while the Maximus IV Gene-Z Sequential read was 495.9MB/s. The Sequential write of the Maximus IV Extreme-Z was slightly behind the Gene-Z with 174.2MB/s compared to 175.8MB/s.
HD Tune Pro 4.01 is an extended version of HD Tune which includes
many new features such as write benchmark, secure erasing, AAM setting,
folder usage view, disk monitor, command line parameters and file
Benchmark Results: The ASUS Maximus IV Extreme-Z was once again ahead in the read and fell slightly behind in the average write. The average read of the Extreme-Z was 511.6MB/s while the Gene-Z was 506.4MB/s. The Average write of the Extreme-Z was 448.8MB/s while the Maximus IV Gene-Z was just ahead with an average write of 450.3MB/s on our OCZ Vertex 3 SSD.
