1. A method for storing data within a hybrid storage aggregate, comprising: receiving an I/O operation associated with a hybrid storage aggregate comprising a lower-latency storage tier and a higher-latency storage tier; evaluating the I/O operation to determine that the I/O operation comprises requested data corresponding to at least one of a non-sequential read operation for data within the higher-latency storage tier, data designated for low latency access, or a read operation for data predicted for frequent access; retrieving the requested data from the higher-latency storage tier; storing a copy of the requested data as copied data within the lower-latency storage tier; maintaining a temperature metric for the copied data; and if the temperature metric falls below a threshold, evicting the copied data from the lower-latency storage tier.
