Example implementations relate to determining a device wear-rate. An example system for determining a device wear-rate can include a plurality of filter drivers to: monitor system requests for I/O associated with a device of the system and transmit information associated with the system requests to a filter manager. The system can also include the filter manager to catalog the information, a service to collate the information across a plurality of machine configurations and workloads, and a processor to determine a wear-rate of the device based on an analysis of the collated information.
