Review on Kingston Digital 32GB MicroSDHC SDC10G2 by Don Merritt

I bought these for a Raspberry Pi project expecting 32 gigabytes. My understanding is that "that's 32,000,000,000 bytes, not 32^9 bytes". The capacity of this card hardly exceeds 31,000,000,000 bytes and does not support the noob image. Read and write speeds were slow for a class 10 card, with write speeds just over 3MB/s. I haven't tested reading, but the Pi is noticeably sluggish compared to another with a real class 10 card.
