How does one go about "refurbing" an SSD? Do they really have guys with tweezers and micro soldering equipment take these apart and replace microscopic parts, then glue them back together?
They just take returns or system pulls, wipe them, re-package them, and re-sell them. I suspect that many sellers who are selling them in bulk don't even bother to test them, given that most of them are very reliable.
Since cheap new ones were becoming more difficult to find, I recently picked up a Samsung 870 Evo 1TB 2.5" SSD from Best Buy's eBay store. It arrived with less than 30 power on hours, less than 50 power cycles, and a grand total of 1.3TB of data having been written on it.
Assuming that it doesn't die prematurely (due to Samsung's apparent inability to write decent firmware for some of their products), it still has a ton of useable life in it if I need it as a replacement.
