Claim:
1. A method comprising: receiving a write request having data directed towards a storage container stored on a plurality of solid state storage devices (SSDs) included in a storage array connected to a node; issuing an input/output (I/O) storage operation to store the data to a first SSD of the storage array; in response to an I/O error detected from the I/O storage operation, incrementing a first counter in a memory included in the node, wherein the first counter is associated with a first I/O error type; associating a set of counters with each SSD of the storage array, wherein the first counter is included in the set of counters associated with the first SSD, wherein the first I/O error type is a recovered error; and in response to the first counter exceeding a first predetermined threshold after a first periodic interval, issuing an alert to migrate the data from the first SSD to a second SSD of the storage array, and placing the first SSD into read-only service, and wherein the first predetermined threshold is chosen such that an expected failure of the first SSD occurs after a migration period for the data.
