Review on Crucial 2TB Portable SSD CT2000X6SSD9 by Nick Esquibel

As at least one other reviewer has noted, the under 4TB X6 uses QLC flash. While copying small files, working with videos, or transferring large files one at a time is fast, you can achieve speeds compatible with a spinning hard drive. While Crucial's marketing department brags about how fast they can write big texts, the legal department hides behind the words "as soon as possible" and similar small print nonsense. Welcome to the modern world of data storage. USB specifications that cannot be deciphered or trusted. USB cables that cannot be trusted according to the specification. Well, storage devices that are sold for speed but don't bother labeling them for speed only under conditions that are pretty limited in the real world.
