Any disk-IO heavy application will brick a card in record time. I worked on a lot of Pi-based systems at my last job (long term time-lapse photography) and we learned quickly to:

1. Buy high quality SD cards

2. Remove as much disk-IO as possible, using an external USB stick for raw data storage, logs, swap, etc

3. If you really need to make it stable, make the OS read-only

You mentioned USB sticks, but I just assumed they used the same type of flash memory that SD cards use?

Aside from USB sticks, any ideas on alternative storage suitable for RPis (something small)? I know you can get eMMC modules that fit into the SD card slot, but I would have guessed they'd have the same issue with writes.
