I think you're going to find out how slow it'll get when you reach the end of 2017 in blocktime.
Whatever you're using to do the download on also, you could try killing as many background tasks as you can if you don't need them (you could also boot the machine in safe mode with networking for Windows to make it faster or kill the desktop for Linux if you don't need a gui).
But if you currently use HDD, but have SSD on your device, you could try make symbolic link on directory which store UTXO.
It's also possible to move the files back from an ssd after the sync has completed so you don't have to worry about doing too many writes on it.
