# Features and Benefits

## Features

* **SSD Storage:** Supports swift data retrieval and reliable data storage.
* **Storage Size:** The minimum cluster size is **2 TiB** and the maximum cluster size is **42 TiB**. It is a usable space; hence, you do not have to reserve free space for optimal performance.
* **NFSv4.2:** The latest NFS protocol version, **NFSv4.2**, allows standard read and write operations directly to storage.
* **Encryption at rest:** Provides encryption at rest, by default.
* **Root squash security:** Network File Storage's built-in security mechanism reduces the risk of unauthorized root-level access from the client machine to the NFS server. Enabling this feature prevents superuser privileges to the root user on a client machine. It also prevents potential attacks on the NFS server when the client machine is compromised.

## Benefits

* **High Performance & Reliability:** **NFSv4.2** protocol provides high availability and durability and the following benefits:
  * Reduced protocol overhead with compound operations and caching.
  * Efficient file operations with minimal server interaction.
  * Live data movement without interruption.
  * Detailed file-level access and performance telemetry.
* **Seamless Management:** Benefit from proactive IT infrastructure management and maintenance with IONOS’s managed Network File Storage.
* **Efficient Data Sharing:** Easily distribute and manage data across multiple VMs within a VDC, with centralized data organization and fine-grained POSIX access control.
