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 performance testing was completed using a Corsair Force GT 240Gb SATA III 6Gbps SSD.
Benchmark Results: The GIGABYTE Z87X-UD3H was the slowest of the three systems we tested today in the CrystalDiskMark SATA testing. Though we are talking about a difference of only 1% on the sequential read, the Z87X-UD3H averaged 506.2MB/s Sequential Read while the fastest board averaged 511.4MB/s. The Sequential Write speed was pretty much the same deal, the GIGABYTE Z87X-UD3H averaged 442.5MB/s while the ASUS Maximus VI Hero averaged 4.2MB/s higher which is again only 1%.
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.
Benchmark Results: HD Tune 5.50 wasn’t so kind to the GIGABYTE Z87X-UD3H, we saw an average read of only 309.8MB/s and an average write of only 291.0MB/s. This is quite a bit slower than we expected to see, but we are in early stages of the BIOS so results may change by the time these hit the retail floors.
