The CrystalDiskMark graphs look a little jumbled, but please note that we have arranged them according to their write performance, slowest to fastest.
This puts the OCZ Summit at the top of the graph for sequential write performance, with an impressive throughput of 193MB/s. The read performance is also very good at 188MB/s, though the Intel X25-M achieved 259MB/s in the same test.
The OCZ Summit was more impressive when looking at the random 512KB performance. The Vertex was our previous leader on this test with a throughput of 124MB/s, but the Summit topped this reaching 150MB/s. The Summit also showed strong read performance, beating both the Vertex and Intel X25-M.
Finally, the CrystalDiskMark random 4KB test which often causes quite a few problems for SSDs. As you can see, the Intel X25-M is still top dog here delivering a phenomenal write result of 51.8MB/s.
The OCZ Summit was pounced in this test for once, managing just 7.7MB/s. This was considerably slower than not just the X25-M but also the Vertex. The Summit's 24.5MB/s read result was more on par with the competition.
