Some Western Digital drives comes with a "recommended workload". Examples of this can be found on some of their product spec sheets
Designed to handle up to 550 TB per year
This isn't a hard limit but, is a recommended design limit based on their claim based on their testing that failure is linearly tied to total data transfer. I don't believe it would void the warranty and I don't believe they would have any means to validate the total data transfer of the drive anyway. While many manufacturers use the MTTF (Mean Time to Failure) metric, WD has started to use a MPbF (Mean Petabytes to Failure) metric which is tied to the recommended workloads of their drives.
Western Digital wrote a white paper to defend their stance titled: Why Specify Workload? if you wanted to read their explanation on why they are choosing to use this metric.
In conclusion, MTTF alone is insufficient to fully describe the field
reliability of HDDs. This results from the fact that HDD failure
rates are more tightly coupled to the total amount of data
transferred rather than the total power-on-time. In order to more
fully characterize the quality level of HDDs, WD will now specify
both the MTTF and the maximum workload at which the MTTF will be met
