ASUS Rampage IV Extreme Motherboard Review

ASUS Rampage IV Extreme Intel X79 SATA III 6Gbps Performance

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 SATA III 6Gbps Testing was done using a Corsair Force GT 240GB Solid State Drive.

Benchmark Results: The ASUS Rampage IV Extreme X79 motherboard was able to hit an average Sequential read of 508.6MB/s and a Sequential Write of 305.5MB/s.
