The RAPID mode is designed specifically to help boost random performance and uses spare CPU power and system memory capacity (up to 1GB) to act as another layer of cache.

very unfair review, nothing about random read access time or access latency that Vertex is quite better. without any doubt the Vertex 4 is highly better but too expensive in fact it is worth in my opinion at most 50% higher or less than $330.
It's $89 for a 128GB. It's about $575 for a 1TB.
It has a full terabyte! Yet it;'s only $89. The OCZ is almost $500.
