Or just use pruned mode if you don't need past transaction/blocks information. Besides HDD with small capacity have lower price/space ratio, you can get 4TB HDD for $100 which have price $0.025/GB while the one you mentioned have price $0.04/GB.
Along with this, if moneys tight, you can buy a second hand hard drive from a trusted and experienced broker generally they'll still be cheaper but you'll have to run a few things first just to check the drive is a big as the broker claims it to be...
Although op doesn't seem to have been here in a while so this might be a void comment.
