Benchmarks: CrystalDiskMark 3.0


The CrystalDiskMark sequential read and write results go a long way in uncovering why the OCZ Vertex 3 240GB was so blindingly fast in some of our transfer and application tests. The sequential read throughput topped 493.6MB/s making it 43% faster than the Crucial RealSSD C300 256GB and 77% faster than the Intel SSD 320 Series 300GB.

With a write throughput of 301.3MB/s the Vertex 3 was 17% faster than the Samsung 470 256GB, which is always fast in its own right. When compared to the Crucial RealSSD C300 256GB it was 35% faster -- a significant performance jump.


When running the CrystalDiskMark random 512K test we still found the Vertex 3 to be extremely fast, particularly when measuring read performance. Here it was 44% faster than the Crucial RealSSD C300 and more than twice as fast as the old Vertex 2 Pro.

Although not as impressive as when reading data, the Vertex 3 still provided strong write results. This time it was 16% faster than the Samsung 470 and roughly 28% faster than the Intel SSD 320 Series and the Crucial RealSSD C300.


Finally, we have the CrystalDiskMark random 4K-QD32 test and again the Vertex 3 240GB is at the top of its class. The read throughput reached 292.7MB/s making it 25% faster than the Crucial RealSSD C300 256GB and more than twice as fast as the new Intel SSD 320 Series 300GB drive.

The write performance was also very strong reaching 250.7MB/s making it 24% faster than the RealSSD C300 256GB and well over twice as fast as any other SSD tested.
