I'm looking for a relatively inexpensive SD card, but I want it to be a minimum of Class 10 as it needs to have decent speed. Size isn't terribly important as long as it's a minimum of 8GBs. Must be a major name brand. (SanDisk, Samsung, Kingston, etc.) And it must be RaspPi compatible.
You can buy a 32GB Class 10 Micro SD card with adapter at Microcenter on sale for $7.99 (I bought a few there yesterday) and they are compatible with the Pi's according to the Raspberry Pi compatibility list. They are listed @ $14.99 usually (i think)
I wanted the 16GB ones, but they were out of stock, so I went for the 32GB ones.
Thanks!
