I read the Raspberry Pi (1?) only supports transfer rates up to 20 MB/s. Does this statement hold true for the Raspberry Pi 2 B?
Would it therefore be worthwhile to spend any money on higher spec UHS-I U1 or U3 cards with maximum speeds of 90 MB/s?
Or could the same budget better be spent on a lower spec (just) Class 10 card (e.g. 45 MB/s) featuring a higher capacity (e.g. 64 GB SDXC instead of 32 GB SDHC)?
