Since OCZ launched their latest Vertex 4 several weeks have passed. Meanwhile they've released new revision of their firmware. According to the manufacturer version 1.4 should be able to give a 20 percent improvement on sequential writes with a 256 Vertex 4. We're really curious if there really is such a significant improvement.

As you can see from the specs OCZ has been able to improve performance of the smaller drive significantly. They promise additional performance for the sequential reads and the sequential writes. Especially the sequential writes profit from the firmware improvements. According to the specs the drive becomes more than 20 percent faster. Concerning sequential reads you get 15 Megabyte more throughput which results in an almost three percent increase.
