These are used drives that have about 35K hours (4 years) of power on time.
Good quality drives to be sure, but maybe not as reliable now as they once were.

Refurbished drive. I've had 4 white label drives running for a number of years without issue, planning on eventually getting 12 more and maxing out my servers.
Unfortunately that's years down the line :(

2nd catch, behind the power on time: PWDIS drives: if you're not using them somewhere with sata 3.2/3.3, you need to use an adapter for the power plug, or some tape, to block pins 1-3 (3.3v) as supplying it to these causes them to reset. Might be worth doing the taping anyway, if you're using an enclosure or cage (where you can't use the adapters)
