Too flight hours !!!

I ordered this drive to remake an old PC whose drive was HS. I do not want to put too much and the other reviews were pretty good so I'm tempted.
At the reception I was disappointed because if the drive working properly, a small test in crystal mark told me he turned for over 37,000 hours. That seems too much for a disc whose announcement does not indicate what kind of "details".
So I sent the product that I was refunded without problem as always with Amazon.
