Hard disk and SSD cost per TB, prices and ratings

Found this cool site that aggregates HDD and SSD prices from Newegg on a daily basis and lists by price per terabyte: http://edwardbetts.com/price_per_tb/

Unfortunately, it doesn't allow filtering or sorting of the data, so here are some quick and dirty examples.

int_hdd=$(links2 -width 200 -dump http://edwardbetts.com/price_per_tb/internal_hdd/)
ext_hdd=$(links2 -width 200 -dump http://edwardbetts.com/price_per_tb/external_hdd/)
ssd=$(links2 -width 200 -dump http://edwardbetts.com/price_per_tb/ssd/)
