Cache

Last updated 1 year ago

PostLab Drive uses a cache file to manage and serve data. This cache acts as a warehouse:

  • When downloading a file, its chunks are stored in the warehouse, ready to be served to your NLE.

  • When you upload a file, it's moved into the warehouse, broken down into chunks, ready for transport as soon as there's bandwidth available.

  • Once the warehouse is full, and there's room needed, the oldest chunks are removed from cache.

  • Once there's room, new file chunks are brought in.

Preferences

Cache Location

PostLab Drive creates a .drivecache bundle in Current location for each Drive and Workspace you connect.

Do not use drives with spinning platter disks (measured in RPMs) or solid-state hybrid drives (e.g. SSHD's or Fusion Drives) for your Cache Location.

Cache Size

If PostLab Drive's cache file is like a warehouse, this is where you specify how big the warehouse will be. You do this by specifying the Current cache size on your local Mac.

Set the Current cache size by:

  1. Using the slider

  2. Entering a value in GB

You can set the Cache Size up to 10000 GB, or 10 TB.

Applying Changes to Drive

Changes are applied the next time you connect to your Team's Drive. If you change Drive's preferences while a Drive is connected, eject Drive, modify the desired preferences, then reconnect Drive to apply your changes.

Drive's Preferences, like all PostLab Preferences, are configured and applied locally to the Mac you're using. This is true even if you belong to multiple Teams and use PostLab on multiple Macs.

Moving A Cache

If your Drive’s Cache Location is low on space, and you wish to enlarge Drive’s cache so more files stay locally cached:

  1. Quit PostLab.

  2. Launch PostLab, then go to Preferences... > Drive.

  3. Set the Cache Location to the new disk, then increase the cache size.

  4. Connect Drive.

If you cannot connect Drive after moving the existing .drivecache bundle, delete all .drivecache bundles for your Drive or Workspaces, reconnect Drive, and PostLab will generate a new one.

Best Practices

  • The bigger the cache size, the better. A larger Drive cache means less data redownloading over time. Your cache can never be too big so feel free to set the Current cache size to more than your free space if you use a non-system disk for caches. Drive will gracefully make cache setting changes in the background, don't worry.

  • Never put your Drive cache on a network drive. Compared to direct-attached storage, local area network throughput has its limits.

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

Move the .drivecache file to

If you move or copy an existing .drivecache with from one Mac to another, any pinned content will also transfer to the destination Mac. The Team Member on the destination Mac will need an external drive that matches or exceeds the size of the transferred .drivecache, and may need to change their .

Cache files need lots of random IOPS, so don't use a spinning disk or a RAID with spinning disks. Any SSD will do, though. If Drive is essential to your workflow,

Set Current location to a folder on a dedicated SSD or NVMe, internal or external.
an external SSD or NVMe disk.
