Since OCZ launched their latest Vertex 4 SSDs several weeks have passed. Meanwhile they've released new firmware and according to them version 1.5 should be measurably faster. We're really curious if there really is a significant improvement.

As you can see from the specs OCZ
has been able to improve mainly the sequential write performance. In this case
they promise that the Vertex 4 should now be capable of transferring 510
Megabytes per second. OCZ engineers have also been tweaking sequential read
performane. Therefore they now promise up to 560 Megabytes per second.
