I'm pretty sure he means brand-new versions, with the idea that high-end enterprise tech like this will eventually become inexpensive consumer-level tech, as it usually does.
Old drives on eBay are somehow usually in great condition and barely used in my experience.
You would be surprised! Enterprise stuff get decomissioned after a set amount of time, it doesn't matter if they still work.
True. In our storage we had complete servers and storage originally packaged in case server in our Datacentar would die. After x years we decommissioned both of them. It was a heartbreaking moment to throw stuff to recycling that was not used and mint packaged. I secretly hide some Pentium I laptops that came with storage and gave them to collectors.
you aren't getting a second hand enterprise drive anyway unless it's bootlegged. it's like infosec 101.
Any modern SSD would have secure erase. Whether it's used or not is uncertain.
