If you need some more storage space, you might be looking at getting a 4 TB or even an 8 TB drive. A new consumer NVMe SSD like a Samsung 990 Pro would cost a fortune, but on eBay, you may have come across a used enterprise drive that is listed for 30% of the price. You might see some pretty great specs like high drive writes per day and power loss protection so you pick it up. But then in reality, when it arrived, it wasn’t just plug and play.
