Capacity and Scalability

Determine how much space you need now and in the future. Models range from 4TB to 32TB total capacity. Bays allow adding more drives later for growth.

Ensure the NAS supports Windows or macOS as needed. Some models offer specialized OS like Windows Server. Confirm compatibility before purchasing.

Warranty and Support

Warranty periods range from 2 to 5 years. Check if hard drives are included. US-based support can help with setup issues.

Physical Form Factor

Desktop models sit on a desk while rackmount units fit in racks. Choose based on available space. Rackmount requires a server closet.
