$HOME/net/people/plgrid/<login>Storing own applications, and configuration files. Limited to 10GB.
$SCRATCH

/net/ascratch/people/<login>

High-speed storage for short-lived data used in computations. Data older than 30 days can be deleted without notice. It is best to rely on the $SCRATCH environment variable. Uses transparent compression.
$PLG_GROUPS_STORAGE/<group name>/net/pr2/projects/plgrid/<group name>Long-term storage for data living for the period of computing grant. Should be used for storing significant amounts of data. Uses transparent compression.

Current usage, capacity and other storage attributes can be checked by issuing the hpc-fs command.

Please note that if a storage space uses transparent compression, the data stored on physical disks is compressed on the fly. The compression might manifest as different sizes reported by utilities like ls and du, where ls by default reports apparent file size (the amount of data in the file), and du shows actual disk usage. In most cases, the apparent file size is larger than the disk usage. The actual disk usage (as reported by du) is used for quota calculation.
