RAM: Opt for NAS systems with at least 2GB of RAM. 4GB or more of RAM is recommended for demanding applications such as virtualization and video transcoding.

4. RAID Configuration:

RAID (Redundant Array of Independent Disks) is a technology that combines multiple hard drives into a single logical unit, providing data redundancy and improved performance. Different RAID levels offer different levels of data protection and performance.

RAID 0 (Striping): RAID 0 stripes data across multiple drives, improving performance but providing no data redundancy. If one drive fails, all data is lost.

RAID 1 (Mirroring): RAID 1 mirrors data across two drives, providing data redundancy. If one drive fails, the other drive contains a complete copy of your data.

RAID 5 (Striping with Parity): RAID 5 stripes data across multiple drives and includes parity information, providing data redundancy. If one drive fails, the data can be reconstructed from the parity information.

RAID 6 (Striping with Double Parity): RAID 6 is similar to RAID 5 but includes double parity information, providing even greater data redundancy. RAID 6 can withstand the failure of two drives without data loss.

RAID 10 (Mirroring and Striping): RAID 10 combines mirroring and striping, providing both data redundancy and improved performance. RAID 10 requires at least four drives.

The best RAID configuration for your needs will depend on the balance you want to strike between performance, data redundancy, and storage capacity.
