titleIt wasn’t that long ago when we took a look at the OCZ Vertex 4, the first drive sporting the Indilinx Everest 2 controller. The Vertex 4 topped just about everything we put it through. When OCZ asked if we were interested in checking out the Asynchronous Agility 4, we jumped at the chance. With the difference between the drives just being the NAND used, it’s always interesting to see what real world performance difference you should expect when going with a budget drive. Not everyone can afford to get top of the line, especially when balancing capacity as well. Let’s see what you will be giving up and find out if it’s worth the difference in price.
