No matter how many I buy I will never have enough hard drive space. It is getting ridiculous. I can fill up at 250 GB hard drive so fast. I am going to have to start buying larger ones and combining them.  I’m thinking it is going to have to be at least a 500 for it to even be worth it.  I might even try to go higher than that.  I figure I will spend less in the long run if I get a bigger one now.
