Western Digital Gold 18TB Enterprise HDD in USED condition.Drive works great, no problems at all.Zero re-allocated sectors. See screenshots of tests/ data.22,200 power-on hours ( ~ 2 years 200 days ) with zero issues. These are rock solid, wouldn't be surprised if it goes for 10+ years. This model's warranty from WD is 5 years, but they're nearly $1000 new.Wiped and ready to be formatted. No original box, just the HDD in anti-static packaging.
