I know blockchain size 80GB
How can I speed up blockchain download?
Later on, I've noticed (and tested) the speed is mainly limited by my harddrive. If you can, use a SSD (if you're not already doing it). When I tested this from a ram-drive, my CPU become the limitation, while running from my laptop's hdd the CPU was mainly idle waiting for the disk.
I have a SSD
kutaypc:~# hdparm -Tt /dev/sda
/dev/sda:
