8. System Updates: Synology regularly releases firmware updates that include security patches and bug fixes. By keeping the DiskStation up to date with the latest software, you ensure that any known vulnerabilities are addressed.

Overall, the combination of RAID protection, disk encryption, user access control, network security, data backup options, antivirus protection, and regular system updates helps ensure data security and protection on the Synology DiskStation DS1813+.

The Synology DiskStation DS1813+ is a network-attached storage (NAS) device that offers various scalability options and expandability features to meet growing storage needs. Some of the key features include:

1. Storage Capacity: The DS1813+ comes with 8 drive bays, allowing you to install up to 8 hard drives or solid-state drives (SSDs). This provides a significant amount of storage space initially, and you can utilize various RAID configurations (including RAID 0, 1, 5, 6, and 10) to optimize data protection and performance.
2. Expansion Units: If the 8 drive bays are not sufficient, you can expand the storage capacity by connecting up to two DX513 expansion units. Each DX513 unit provides an additional 5 drive bays, allowing you to add up to 10 more drives to the DS1813+.
3. High Capacity Drives: The DS1813+ supports large-capacity drives, including 16TB drives, which allows for a maximum raw storage capacity of 160TB (with 10TB drives) when fully expanded with the DX513 units.
4. SSD Cache: To enhance performance, the DS1813+ supports SSD caching. By installing SSDs as cache drives, frequently accessed data can be stored in the faster SSDs, resulting in improved read and write speeds.
5. RAM Upgrade: The DS1813+ comes with 2GB of RAM by default, but it can be expanded to a maximum of 4GB. Increasing the RAM can improve the overall system performance, especially when handling multiple concurrent tasks and running resource-intensive applications.
6. Expansion Ports: The DS1813+ features two expansion ports that allow you to connect additional Synology expansion units or other compatible devices for further expansion or functionality.
7. Virtualization Support: The DS1813+ is compatible with various virtualization technologies, including VMware, Citrix, and Microsoft Hyper-V. This allows you to integrate the NAS into existing virtualization environments, providing storage for virtual machines.
8. Synology DSM: The DS1813+ runs on Synology's DiskStation Manager (DSM) operating system, which offers a wide range of built-in applications and third-party packages. DSM provides a user-friendly interface and allows for easy management and customization of the NAS.

Overall, the DS1813+ offers a flexible and scalable storage solution, allowing you to expand the capacity, improve performance, and integrate into existing IT environments as your storage needs grow.
