Power on time is like 50k hours tho... Thats like 6 years...
I would not risk it. Im currently in move to replace my 500GB WD which has 33k hours of work.
For usual stuff to keep on it, yes, for important? No.
Just to be clear, you don't trust a brand new drive to hold your data either. Anything important needs to have backups right from the start.
It's an old drive, that's for sure and only 320Gb, but for $4... Why not!
Be sure to match the s/n number on the screenshot to the drive in case they are trying to sell a bunch of these (usually the case) under the same screenshot.
