CrystalDiskMark 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.

CrystalDiskMark Benchmarks
Synthetic File Transfer Tests

We have a theme developing here; the 128GB Vertex 4 had another inverted score, this time in three of the CrystalDiskMark tests.

The Sequential Transfer test and 512K Transfer tests have nearly identical charts; the 128GB Vertex 4 beats out the Corsair and Patriot Pyro SE drives in the write tests and posts decent reads.

In the 4K Transfer test and 4K QD32 Transfer test, we see the 128GB Vertex 4 suddenly come to life, posting the best numbers across the board in both read and write tests (except for a modest score in the 4K QD32 write test).
