Cache

Drive uses an independent cache file, apart from the cache Postlab uses. The maximum size and location of the cache can be set in Postlab's Preferences, under Drive:

Changes are applied the next time a Drive connects. If you change settings while a Drive is connected, reconnect it for the changes to be applied. Settings are for all Drives on your system, so if you're in multiple teams, these settings apply to all caches - on this computer.

Best Practices

  • Place your cache on your fastest disk, typically the internal SSD, or an at least as fast external disk. Using a slow disk for caches will result in significantly slower uploads.

  • Drive LOVES cache. The more the better. The larger your cache, the less data has to be redownloaded, so give it all you can spare. If Drive is essential to your workflow, we recommend dedicating a 1TB external TB3 NVME disk to the cache.

  • You can't have a too large cache, so feel free to set it to more than you have free space left. Drive will handle it gracefully, don't worry.

  • NEVER put your Drive cache on a network drive. No, also not on a Jellyfish's Cache share. 10GE only gets you so far, and it's nowhere near the 3000MB/s Apple SSDs give you.

  • Uploading huge files? Make sure your cache is larger than the largest file you're uploading. Uploading a 25GB file with a 20GB cache will not work.

Moving A Cache

If you don't have enough space for your cache, and would like to enlarge it to ensure more files are kept in cache, you can move a cache:

  • Quit Postlab

  • Move the .drivecache file to an external drive. The faster the drive, the better!

  • Start Postlab, go to Preferences > Drive

  • Set the cache location to the new disk, and increase cache size.

  • Connect Drive.

If the last step doesn't work after moving the cache, delete the cache and Postlab will build a new one.
