Next up is optical discs and early flash memory variants such as Sony Memory Sticks, MMCs, xDs, and SD cards.

When is the last time you used one of these formats?

I vote for SmartMedia[0] in a FlashPath[1] adapter. It’s the “cassette adapter” of memory card readers.

Watched a 4k blu-ray last night. Let me know when streaming services are sending video with peaks of 100Mbps h.265 and audio with peaks of 4Mbps (and when I can get a home connection that can handle that). And when I can use streaming when utility power is unavailable and my telco DSL is too (they apparently don't have a battery at the remote terminal)

SD cards seem alive and well, although usually micro these days.

Sony Bravia Core is the closest with peaks of 80 Mbps.

The internet connection of course, they can't help you with.

If you're including micro SD cards, there's literally one on my phone right now. And optical discs remain good for watching movies, although I agree they're on the decline everywhere else. The rest I haven't seen in forever.

I was not including SDXC or even SHDC cards, only SD. I am trying to find a maximum capacity SD card to use in a Palm T|X, either 1 or 2 GB. Back when SDHC first came out, I often ran into issues with 2 GB SDHC cards not working on older devices. I think being difficult to find is another criteria to qualify as obsolete.

The odd thing about high capacity SD cards in general is that they are generally used as fixed storage. I have a 256 GB card that I put into a 11" laptop when I bought it and I haven't seen it since. I haven't used a CF or SD card like a floppy since storage hit 4 GB.

I agree that I spoke too hastily about optical media. Even modern gaming consoles have optical drives.
