Hard drives are pretty much the least reliable component in a computer.
They are also the part you want to fail the least, because you will lose data when they fail.
Refurbished drives have very low warranties, and have a reputation for failing. They are untrustworthy.
So, don't buy a refurbished drive. As much as speed is good, buying a disk that is so unreliable that it has already failed once is definitely a bad deal.
Also, the performance difference between different brands for their equivalent models is very small.
