+Good performance and a stable connection to the Postgres database is critical to a smooth Immich experience.
+The Postgres database files are typically between 1-3 GB in size.
+For this reason, the Postgres database (`DB_DATA_LOCATION`) should ideally use local SSD storage, and never a network share of any kind.
+Additionally, if Docker resource limits are used, the Postgres database requires at least 2GB of RAM.
+Windows users may run into issues with non-Unix-compatible filesystems, see below for more details.

 The Immich Postgres database (`DB_DATA_LOCATION`) must be located on a filesystem that supports user/group
 ownership and permissions (EXT2/3/4, ZFS, APFS, BTRFS, XFS, etc.). It will not work on any filesystem formatted in NTFS or ex/FAT/32.
 It will not work in WSL (Windows Subsystem for Linux) when using a mounted host directory (commonly under `/mnt`).
