I love computers since I was a kid. I’m always fascinated with new technology, especially in the PC world. Many years ago, I was curious if the reviews I read were true and real. So, why not test them myself and share my first-hand experience? And thus, here we are. Thanks for reading!


  1. In time these Samsung 840 Evo and Pro SSDs will be super cheap to buy on Ebay (gently) used. That’ll be a good time to buy I think
