                Home NAS Comparison
              
          
    The comparison is done based on 5 years usage and 1TB of storage. Below are the rationale

Most hard drives has warranty till 5 years
After 5 years some revolutionary technology may replace existing
1 TB is a good amount of data a beginner YouTuber will produce.

Assumptions


If the 1 TB storage need changes the comparison would be void.
Also this excludes the taxes as it changes by geography and time.
