Which one to buy? I don't know what to get, there are too many options out there. Based on your experience/knowledge, which would you recommend me? For what I've saw, this two are the best options..

1. Western Digital My Passport Essential SE 1TB External USB 2.0 Porgable Hard Drive

2. Toshiba Canvio Plus 1TB External USB 2.0 Portable Hard Drive

I've had a Western Digital external drive for over 5 years with no problems at all. It's only a 100G. Performs well and has never left me down. I was looking at the 1TB external drive a few weeks ago and decided I didn't need that much memory so I'll just keep my older one instead.

Do you really need that much memory??

I would recommend whichever is cheaper because I compared them and they were basically the same
