I’m not sure why it would be different using SSD if you’re using the same config and workload but I wouldn’t worry too much about this size of load causing the drive to fail anytime soon. You may be able to reduce the load by disabling internal monitoring. To do that, set this in the config:
[monitor]
store-enabled = false
