Scratch space for RStudio Workbench is highly variable. A lot of scratch work can be pushed to file shares and databases, as opposed to local disk. Generally speaking, R will not need as much scratch space as SAS since R does not write its intermediate data files to disk. Nevertheless, it's always good to have some scratch space on the R server. Depending on data volumes and the number of users, 250 Gb - 1 Tb of disk space per server will be sufficient for most use cases. If you plan to support large data workflows, then we recommend more than 1 Tb of disk space.
