The cache on the OCZ Summit drive is really what will help it stand
out from previous solid state offerings. While having cache on board with
standard hard drives has been the norm for many years, it was long thought
that the speed of flash memory negated the need to have dedicate memory on
drives for performance reasons. After all of our experience with JMicron
controller and the very slow writes they were famous for, we have learned
that cache is still a technology SSDs can take advantage of."
