I'm trying to figure out if it would be worth spending an extra $30-$40 for a 7200rpm 64mb cache drive. I found a couple Seagates that fall into that category. But if the drive is used for music, movies, and some apps that I didn't need running on the ssd will there be a big enough improvement over the green? I'm not sure why, but the Frys website has the Western Digital listed as a Sata 3 5400rpm drive, but the one I got is an intellipower Sata 6. The model numbers are identical, but the Frys employee said that Western will sometimes use same model #'s from discontinued drives for new ones and change packaging.
