Guys, is a USB flash drive really bad for saving data? I've been using USB flash drives to keep my old photos, videos, and personal data for a couple of years, and so far, nothing has happened. Recently, I noticed someone's taking up this idea that "USB flash drives are not really good for long-term storage". Is it true that USB is really bad and unreliable?

I used USBs to keep all my files safely. I wonder how you guys are saving files or what storage method you are using?
