# Job: Cache Particles on SSD

## **Description**

Cache particles on a workstation before running a job that requires the particles. This is useful when working with many particles, as it may take a long time to copy these over to the SSD. Pre-caching allows you to free up the GPU that would've normally been acquired during the caching process, allowing other jobs to use the GPU while caching completes. Read more about [SSD caching in CryoSPARC](/setup-configuration-and-management/software-system-guides/tutorial-ssd-particle-caching-in-cryosparc.md).
