Using a faster MicroSD card like a SanDisk Ultra MicroSD cards is the easiest way to make your Raspberry Pi 2 run faster.

This SanDisk 8GB MicroSD card has enough storage to install 2 or more operating systems on the Raspberry Pi 2. I think 8GB of space should be the minimum size of SD card you use if you are planning to use the Raspberry Pi for using desktop operating systems like Raspbian, OpenElec, Arch Linux, etc since some operating systems for the Pi can use many GB of space once you install all your programs on the Pi 2. You’ll also not save much money by using a 4GB MicroSD card instead of a 8GB MicroSD card because a 4GB card cost around $5.50-5.80. The money savings is sometimes less than a dollar by using a 4GB MicroSD card instead of a 8GB card. Most 4GB cards are also slower, and maybe less reliable than SanDisk Ultra series of MicroSD cards. The slower speeds, and lower reliability of cheaper 4GB cards can make using the Pi 2 slower, and less reliable with more random reboots, freezes, and slowdown problems.

The 48 MB per second read speeds, and faster write speeds makes this card one of the best MicroSD cards for the Raspberry Pi 2 because your Raspberry Pi 2 will startup faster, and open programs, and files a lot faster than using a slower MicroSD card. The faster write speed of this MicroSD card will make installing the operating systems, programs, and files on to the MicroSD card a lot faster than using a slower MicroSD card.
