I haven’t made the jump to an external SSD. I still use external hard drives to store old backups, movies, shows, images, and videos. External SSDs never really seemed “affordable” enough to me, so I sacrificed the transfer speeds in favor of lower cost per GB. If you’re the proud owner of one of the newer external SSDs, boasting 1,000–4,000 MB/s speeds, you might be surprised to know that these blazing-fast speeds require way too many prerequisites. And most people are probably using systems and cables that aren’t equipped with the bandwidth needed to deliver these speeds. Your external SSD might feel fast enough to you, but unless you monitor the real-time transfer rate, your drive could be operating at only half its speed, or even worse. External SSDs rated for USB4 need a 40 Gbps connection, which is easy to break if even one link in the entire chain doesn’t support the required bandwidth.
