I think I may buy a 128gb SD/SDXC card to store my music, but I'm wondering if it'll be fast enough so that albums play in Itunes without lag/hesitation. Anyone have any experience with this?

Yes, you can play music and movies off the SD card with no problem, but don't cheap out on the card. Get one that is at least class 6 and you should be fine.
 
Apple's Tech Specs only confirm SDHC compatibility on 13" MBAs. SDXC compatibility is listed on MBPs with SD slots.
 
Even if the Air uses the USB bus and has a max speed of 480 mb/second you don't have sdxc cards yet that can saturate it. I think the fastest sdxc cards read at 95 and write at 45 mb/s.

Someone correct me if I am wrong.

Hm, ok. I guess the thing is that 64GB SD cards and above have to be SDXC, correct?
 
I just ran an benchmark on my 64GB class 10 Sandisk Ultra card on my 2012 MBA. 10MB/s write, 35MB/s read.

By comparison my SSD was 400MB/s write and 450MB/s read.
 
hell, I use a sandisk extreme sd card to record two tracks of audio at a time straight from my DAW. basically I'm using the sd card slot as a mini recording drive. your more than good for what your trying to do.

Is there any indication of what bus the SD Card reader is using on the 2012 Air?

The Extreme Pro SD Card from SanDisk is claimed to go "up to 95 MB/s" vs the "up to 30MB/s" of the Ultra SD Cards.

Pricy at ~$300, but perhaps a more flexible option to add space to an MBA. I'm thinking Parallels or Boot Camp partition, media storage, etc.
