After some system upgrades, I have 2 extra Seagate 3TB hard drives, model ST3000DM008. These are brand new and still sealed in the original box. Date of manufacture is February 4, 2019 so they are not old stock or anything like that - Amazon is just being stupid and not letting me return them without me taking a loss, so I'd rather pass the savings along here. $75 each. They sell for $85 new on Amazon: https://amzn.to/2F5umgr Weekday pick up in Burlington, MA near the mall between 10 and 6.
