I am thinking of using an SD card with a USB adapter (instead of a USB
memory stick) as way of having portable data.

(Q1) Is there any significant difference between the two in terms of
function or performance?

(Q2) Could a micro-SD card (with a "size" adapter) always be used in place
of a regular sized SD card?

Function no (except technical details you don't need to care about);
performance depends on what you buy.

It's actually a lot easier to identify high-speed SD cards than
high-speed USB sticks, because they have actual speed ratings. Class 2
are slow, class 6 are fast, and class 10 are round the corner.

Yes.

There are still SD-only USB adapters out there, so if your SDHC card
doesn't work in one, that'll be why.

MicroSD to SD size adapters are universal, they're just wires and a
shell.

Depends on tha Card and the adaptor. FWIW I have both USB sticks and
SD cards with an Adaptor. I couldn't tell you of any noticable
difference.

Yes, I do this also with the kids T4 DS games ;)

No problems at all here.
I am posting this from a Shivaplug running Linux on a 16Gb SD card
(formatted to EXT2).
I use that 16Gb card on the USB slots with a �1 adapter purchased
from the PoundShop. All work swimmingly fast.

MicroSD cards also no problems. I use several with an SDCard adapter
so I can carry around a few bootable distros is my pocket for quick
boot and maintenance of PCs. They are robust but so tiny and you can loose
them if you are not careful.

Yes. (Almost) all SD cards have a write protect switch.
Write protect switches on USB sticks are rare, to say the least
:-)
