USB-C transfers power as well. Are you really using cds and floppies in the year of our lord 2020, or are you just strawmanning?

I use them quite often, as I work with a lot of legacy hardware and software.

  I've got a USB DVD burner hooked up right now. Easy as falling off a log.

Burning cds/dvds is still a very convenient and dense affordable form of offline storage for backups and/or content hoarding.

  Doesn't optical media degrade to the point of no longer being readable after a few years?

    My personal experience has been surprisingly good even with cheap TDK CDRs I burned in the 90s still reading just fine decades later. For especially valuable data you want to preserve for 100+ years, there are "archival quality" discs [0] [1].

  Really? With the cost of SD cards what they are? Like, I can get a 128GB SD card for $30. That would be 170 CD’s - nearly 30 DVD’s - which will eventually suffer disc rot. DVD/CD write speeds are very slow, comparatively speaking to even USB 2.0 transfer speeds - and increasing the speed, in my experience, makes exact copies of discs extremely error-prone. Explain how this is efficient? Genuinely curious, with the price of solid state storage these days. (I understand even solid state storage has a shelf life, but at least it also can’t be so easily harmed as a CD/DVD)

    SD cards are not intended for long-term archival purposes, not 10+ years. They don't go bad per se, but the data on them may not be readable after slowly discharging offline in cold storage for a decade or more. https://en.wikipedia.org/wiki/Data_rot#In_storage https://en.wikipedia.org/wiki/Data_rot#In_storage

    How about bluray? 25GB for ~$0.70. Personally had so many sd cards, and even usb sticks fail that adding another type of storage as a backup for important files really makes a lot of sense.

  A DVD holds, what? 14GB max? A microSD card can hold 500GB. DVDs (and even blu-rays) are far from "dense". They also require an order of magnitude longer to write, lose their data to bit rot faster than SLC flash, and require devices with mechanical motors for both reading and writing. I wouldn't call them convenient compared to flash memory, and I'm surprised anyone would.

    How long is SLC flash good for? Archival quality optical discs are marketed as having a 300+ year lifespan. I've never viewed SD cards as something appropriate for long-term offline storage, is SLC flash exceptional in this regard? I was comparing the convenience of optical to tape, which is bulky and annoying, and in my experience quite unreliable.
