# Where should I store PostLab's caches?

In PostLab there are 3 categories of caches:

1. Productions - `Preferences > General > DEFAULT PRODUCTION LOCATION`
2. Drive - `Preferences > Drive > CACHE LOCATION`
3. Your host NLE - Final Cut Pro, Premiere Pro

Store these caches on a dedicated SSD or NVMe disk, whether internal or external over Thunderbolt 3/4.

In Final Cut Pro, set your Library's Cache to a folder outside your Library.

For Premiere Pro, if you're using Projects with PostLab Productions, PostLab creates Scratch Disks for you in the same folder where your Productions are cached (`Preferences > General > DEFAULT PRODUCTION LOCATION`).

{% hint style="danger" %}
Do not store PostLab's caches on:

* A spinning disk or a RAID with spinning disks.
* Solid-state hybrid drives (e.g. SSHD's or Fusion Drives).
* Shared storage - network attached storage (NAS), a storage area network (SAN), or cloud storage (e.g. PostLab Drive).
