I bought Rasp 3 past few days with NOOBS sd card (Complete CanaKit on Amazon) and try to install it. I chose to install Raspbian only in NOOBS interface then.But it took nearly 5 hours for just 700 Mb,to say uhmm , downloading and extracting with speed about 0,1->0.5 Mbs... My SD card is Kingston 16gb class 10. Could someone tell me why it took so long to install the OS?
