ssd_path, which is a fast drive location on the worker node that particles will be copied to and read from when being processed. CryoSPARC manages the SSD cache on each worker node transparently.
Cache particle images on SSDoption turned on, particles will be automatically copied to and read from the SSD path specified. Furthermore, if multiple jobs within the same project require the same particles, the cache will be re-used and the copying step is skipped. If more space is needed, previously cached data will be automatically deleted. Setting up an SSD cache is optional on a per-worker node basis, but it is highly recommended. Nodes reserved for pre-processing (motion correction, CTF estimation, particle picking, etc.) do not need to have an SSD.
--ssdpathto specify the path of your SSD drive when you connect your worker to your instance. If you don't want to configure an SSD cache for a workstation node, specify the

--ssdreserve: The minimum amount of free space to leave on the SSD (MB)

Cache particle images on SSD. Turn this option off to load raw data from their original location instead.
Cache particle images on SSDparameter is always on for every job you build, but if you'd like to keep this option off across all jobs in a project, you can set a project-level default.
