Were there two 10 TB hard drives instead of a single 20 TB hard drive and one of them would die, there would be a 50% chance that the file I was looking was still accessible. And if it wasn’t, rebuilding the dead hard drive would only take a day. LaCie is a company popular for it’s Thunderbolt storage.
