Nope, this is not a check. Unfortunately.
Storage on the Raspberry Pi is pretty limited to the microSD card, which qualities greatly differ – see benchmark.
If you want to go over the 200MB (for now) barrier of the biggest microSD card (like SanDisk – not benchmarked yet), you will need to connect an external drive via the USB port… or use the Western Digital PiDrive, which directly integrates a USB connector on its electronic board.
WD released the PiDrive 314GB for Pi day 2016, I just got it and share with you the pictures. I will add the drive to my benchmark list.
