Abstract
Provided is a predictive read ahead system for dynamically prefetching content from different storage devices. The dynamic prefetching may include receiving requests to read a first set of data of first content from a first storage device at a first rate, and requests to read a first set of data of second content from a second storage device at a different second rate. The dynamic prefetching may include determining different performance for the first storage device than the second storage device, prioritizing an allocation of cache based on a first difference between the first rate and the second rate, and a second difference based on the different performance between the storage devices, and prefetching a first amount of the first content data from the first storage device and a different second amount of the second content data from the second storage device based on the first and second differences.
