Trying to make decision on hard drive solutions? I purchased a Samsung 500GB ($79.99) and 1TB ext drive ($137.99) on Black Friday. I also purchased Western Digital 1 TB for $42.99)!! I am trying to decide what makes sense. Most of my computers have at most 250 GB. Is SSD worth premium price, or should I go for the larger mechanical drive and save $$! Any perspective would be appreciated!
