Embodiments of the present application disclose a method and device for balancing disk wear in a distributed cluster, electronic equipment and a medium. The method comprises: determining a source disk for data migration out and a target disk for data migration in from a cloud storage distributed cluster; determining to-be-migrated data from a write cache corresponding to the source disk; and migrating the to-be-migrated data from the write cache corresponding to the source disk to the target disk. The technical solution can directly migrate data from the write cache of the source disk to the target disk, without the need to eliminate and refresh the to-be-migrated data in the write cache to the source disk before data migration, thereby reducing the number of write refreshes of the source disk, slowing down the shortening of the service life of the source disk, and improving the data migration efficiency.

The application relates to a UV lamp drying device, which comprises a box body, a lampshade arranged in the box body, a lamp plate arranged at the bottom of the lampshade, a heat cavity formed by the lamp plate and the inner side wall of the lampshade, a UV lamp arranged in the heat cavity, a wind cooling assembly arranged in the box body, the wind cooling assembly comprising a cold air fan arranged at the top of the box body, the air outlet end of the cold air fan being communicated with the heat cavity through a ventilation pipeline, and a plurality of air outlets for air outlet being arranged on the lamp plate. The application has the effects of prolonging the service life of the UV lamp and improving the product quality of printed products.
