| Abstract | Embodiments of the invention relate to calculation of error rate for data storage which includes determining a completion status of a read operation of data stored in a storage device, the completion status being one of at least partially complete or not complete. The fault monitoring count is incremented based on the completion status being not complete. The fault monitoring count is decreased based on the completion status being at least partially complete. The fault monitoring count being decreased according to a value based on the number of bytes successfully read. The error rate indicator value is being calculated based on an exponential decay rate related to the number of bytes read. The fault monitoring count threshold is monitored every time the fault monitoring count is incremented and the storage device is identified as faulty once the threshold limit is exceeded. |
