System and method for predicting future disk failures

A non-transitory machine-readable medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations of predicting disk failures, the operations comprising:

• receiving a diagnostic parameter of a target storage disk of a storage system having a plurality of storage disks;
• determining a first weight factor from a first quantile distribution representation based on a value of the diagnostic parameter, wherein the first quantile distribution representation represents a quantile distribution of values of the diagnostic parameter of a set of known failed disks;
• determining a second weight factor from a second quantile distribution representation based on the value of the diagnostic parameter, wherein the second quantile distribution representation represents a quantile distribution of values of the diagnostic parameter of a set of known working disks;
• calculating a third weight factor for the diagnostic parameter for the target storage disk based on the first weight factor and the second weight factor;
• and
• determining a probability of potential disk failure of the target storage disk based on the third weight factor.
