I realized something tonight when I checked the prices of 500GB to 1.5TB 3.5inch hard disks. They are now cheaper to use for data or media storage than DVD-R or similar optical media (of reasonable quality).
I am planning to build a media server to store the stuff I download from *******. It would also replace my ancient pc working as my ******* download PC. At least using that, I can add more HDDs if i need more capacity in the future.
