i have a 250gb drive that i actually bought used about 10 years ago. no idea how long it was "used" but it could be a 15yr old drive for all i know. it's still working just fine though but i got to thinking the other day it might be at the end of its life cycle. i have windows on an SSD but all of my personal files/games on the older HDD. should i upgrade and toss it or just keep working and not worry about it?
