SSD full in the middle of a Premiere Pro edit?

You drop a clip on the timeline and Premiere throws a disk-full warning, or Media Encoder refuses to export because the scratch disk is out of space. The quick wins are worth knowing. Premiere keeps two space hogs you can clear: the media cache, under Edit then Preferences then Media Cache on Windows or Premiere Pro then Settings then Media Cache on macOS, where Delete removes conformed audio and index files; and the scratch disks, under File then Project Settings then Scratch Disks, which default to the folder next to your .prproj and hold previews, auto-save and captured media. Point those at another drive, or delete the unused cache, and you buy some room back.

The catch is that none of this moves the real weight: the camera originals. On a 1 TB or 2 TB SSD, a few 4K or 6K shoots plus their proxies fill the disk again within days, and you are back to hunting through Finder or Explorer, deleting shoots you might still need. Ten minutes of cleanup becomes half a day, and you delete the wrong thing once or twice a quarter.

Sanbila removes the heavy half for good. Your originals upload to cloud storage on import, with a redundant backup copy, and only the light proxies, 10 to 50 times smaller, sit on your SSD. The local cache has a size limit you set, from 5 GB to 500 GB, and when it is reached, least-recently-used eviction removes the oldest proxies first and never touches an original. Nothing you delete is lost, because a cleared proxy re-streams from the cloud on demand.

Pin the rushes of the project you are cutting now so they are excluded from eviction, and unpin them at delivery. You still keep Premiere's media cache on a fast drive for conformed audio and indexes, but the disk no longer fills with camera files you are not using. When you do need an original, Premiere reads it via a local mount at export, and the full resolution file streams in without ever living on the SSD. The disk-full warning stops being a daily event.
