Tesla Dashcam USB Drive Size Limit Explained
Tesla does not publish a hard size limit for Dashcam drives, but 128GB is the practical minimum if you want more than a few hours of history.
Tesla does not publish a hard size limit for Dashcam drives, but 128GB is the practical minimum if you want more than a few hours of history. Use exFAT when you format the drive, since it supports large volumes like 1TB or 2TB without the file size limits of FAT32. Here is a rough estimate for multi-camera footage (actual size varies by software and scene complexity):
- 128GB: about 25 to 35 hours of rolling footage
- 512GB: about 100 to 140 hours
- 1TB: about 200 to 280 hours Remember that SavedClips and SentryClips do not overwrite as quickly as the RecentClips loop, so extra space helps you keep important events.
