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.
Our CrystalDiskMark scores look much like the HD Tune results from the previous page. The Intel 335 series SSD offers very good performance but trails the highest-performing drives by a couple of percentage points here. Performance at the higher queue depth, however, is the best of the SandForce-based drives; only the Vertex 4 and Samsung products performed better in the QD32 test.
