 If you are a **CRC supernode** or install all the components of the Elastos blockchain:

 * **RAM**: **32 GB** or more
-* **HDD**: **200 GB** or more
+* **HDD**: **300 GB** or more
   * A solid-state drive (SSD) is a plus but not a must. A hard drive (HDD) should be OK.
   * Disk usage will always increase because blockchains are growing. You should monitor your disk to ensure it is big enough to hold all the programs.
 
 A single chain may require fewer resources. For example, you only install the mainchain as a verification node.
