can we buy those more reliable faster enterprise HDD?

Some places online sell them yes. You might find them at specialty computer suppliers locally as well, but they're not going to be for sale at your local electronics chain next to the washers, TVs, and HP computers. They cost quite a bit more than consumer ones though.

QUITE a bit more. You can find some on Newegg, but they're overkill for consumer applications.

The reason is that I want a reliable hardware. Hard Drives are become bigger and cheaper , which makes me feel that the quality is decreasing severely. I think businesses are thinking that hard drives are closer to something you need to dispose of every 1-2 years. back in the day, I cant remember any one replacing hard drives, it will live almost forever.(pre 2000 probably). The manufacturing companies that most people buy from, WD and Seagate, have high failure rate from reviews I read. I am not sure what other brand I should pick

This is why I look for reliable ones, cost more, but lasts longer and peace of mind.
