I have a Macbook with 120GB of storage and I really want more space to fit more music and movies and whatnot onto it without feeling like I'm pushing my computer to it's limits. The obvious solution is an external hard-drive but I've research Iomega, Western Digital, Seagate, etc and it seems every product/manufacturer has it's people who love them and had no problems along with people who hate them and had their drives not work, break in a couple weeks, or within a few months and just stop working, etc. External is definitely cheaper but with the low reliability rates it's putting me off. Not to mention it seems they slow people's computers down. Then I read about Western Digital's 320GB internal HDD which is almost triple of what I have now. With this I wouldn't have to worry about slow transfer speeds and my MB not recognizing the external, but then the trade-off is much lower HDD space options as well as them being more expensive. However internals are more reliable correct? I suppose this is a pointless question as if I ask for people's opinions I'm going to receive what I just said - some people who loved their externals and other's who hated it. Basically I really want to know what people think of upgrading your internal hard-drive as opposed to going the external route?
