Here's a quick cautionary tale for other RX1 users who might try out a Transcend WiFi SD card as part of their street photography kit:
Purchased a Class 10 Transcend SD WiFi 32GB card so I could take snapshots, wirelessly transfer them to my iPhone, process them, then upload to the social network of my choice. Works flawlessly when shooting in JPG or JPG+RAW and also shooting in "Single Shooting Drive Mode". Was generally pleased and excited to use this when I was out and about shooting events and such.
The other night I went to see a rock show, got right up front and started shooting JPG's no problem. The band was amazing, so got really excited and wanted to crank out more shots, so I switched from JPG+RAW, to RAW only, and switched from "Single Shot" to "Cont. Shooting" mode. I fired away throughout the night, and had no problems that I was aware of. The previews in camera looked great, so I had no cause for alarm. When I got home however, I found out that the RAW files were corrupted, as the card couldn't write fast enough to keep up and introduced corrupted lines of pixels in the images. The thumbnail previews the camera used to playback the file in camera were fine, but the underlying RAW files were damaged.
Ug. This was the first "official" show of Bad Things, an amazing band that includes Shawn White (of snowboarding and skate boarding fame) as part of the line up. Who knows, could be in important show to look back on one day. To see almost 80% of all my shots corrupted really bummed me out. The shots that weren't corrupt were the ones I shot before switching to "Cont. Shooting" mode, as I'm guessing the card could handle writing the files when shot one at a time.
Yes, I'm able to fix some of them in post, but the fixes aren't exactly quick and easy.

Corrupted RAW file shot on RX1 to a Transcend WiFi 32GB SD card.
I should have switched cards to my Sony 32GB 94MB/s card, which has proved itself capable of handling shooting RAW in "Cont. Shooting Mode", so shame on me for not testing the Transcend first. Figured I'd pass along the warning to other shooters...
