I got this (http://www.simpletech.com/commercial/products/spu35320.php) external HD for xmas, wondering if it's decent or if I should return it, I can't find much on here about it. Wondering if I should return it, and pay a little more, to get this one (http://eshop.macsales.com/item/Other World Computing/MAU8F7250GB8/). Mainly it will be used for Time Machine (I take up around 80 GB on my computer), and a little bit of storage. Being portable is nice, but by no means necessary. The same thing goes for Firewire 800. Thanks all.
