Benchmarks: CrystalDiskMark 3.0
Despite closely matching the Vector drives in our application tests and beating them in the copy tests, the OCZ Vertex 450 256GB was slightly slower in our first CrystalDiskMark synthetic test. With a throughput of 467.1MB/s it was around 6% slower than the 499.2MB/s transfer speed of the Vector 256GB.
Despite being slower in the sequential read test the OCZ Vertex 450 256GB was able to match the Vector 256GB in the sequential write test.
When measuring random 512K performance the OCZ Vertex 450 256GB was again able to match the Vector 256GB drive, making it much faster than the Vertex 4.
The OCZ Vertex 450 256GB also matched the Vector 256GB in our random 512K write test.
The OCZ Vertex 450 256GB slips away from the Vector drives in the random 4K-QD32 test with a throughput of 326.2MB/s. Despite being over 55MB/s slower the Vertex 450 256GB still managed to convincingly beat the Samsung SSD 840 Pro 512GB and Vertex 4 256GB drives.
Although the OCZ Vertex 450 256GB was slower than the Vector drives in the random 4K-QD32 test, it had no issue out performing them in the write test. Again we suspect OCZ has made some improvements to the firmware since we tested the Vector drives last year, improving the drive's performance in this test.
