I know SD SLOTS can generally accept MMC cards, but I don't think MMC slots
will take SD cards; there are few devices which really need MMC cards
exclusively now.
What device are you trying to use a SD card on?
The "80x" is the data rate in CD-ROM drive speed, and 1x = 150kbps, so
80x=12000kbps.
That's a peak rate, if your device won't go that fast, you won't see any
benefit. A high-pixel digicam might actually crank data fast enough to see a
difference, a mobile phone probably won't.
You can likely get away with the cheapest good-quality card you can find.
I've got a noname 128M card in my digicam, has been perfectly fine for almost a
year of moderate use.
