CrystalDiskMark x64 Benchmarks
CrystalDiskMark is a synthetic benchmark that tests both sequential and random small and mid-sized file transfers using incompressible data. It provides a quick look at best and worst case scenarios with regard to SSD performance, best case being larger sequential transfers and worse case being small, random transfers.
The Samsung SSD 960 Pro 1TB drive puts up some more excellent numbers here, but does trade victories with the Intel SSD 750 or OCZ RD400 in a few spots. The Samsung drive performed best with large sequential transfers, but took a few hits in the 4K transfer tests.
