Claim:
1. A method of proactively addressing conditions that affect input/output (′I/O′) performance in a non-volatile semiconductor storage system that includes a plurality of non-volatile semiconductor storage devices, the method comprising: monitoring, for a non-volatile semiconductor storage devices, one or more non-volatile semiconductor device-related performance attributes; determining, for the non-volatile semiconductor storage device in dependence upon the one or more non-volatile semiconductor device-related performance attributes, whether the non-volatile semiconductor storage device is exhibiting a behavior that may affect I/O performance, including determining whether the non-volatile semiconductor storage device is about to perform an internal cache flush; and responsive to determining that the non-volatile semiconductor storage device is exhibiting the behavior that may affect I/O performance, scheduling a proactive operation associated with the behavior on the non-volatile semiconductor storage device.
