Seagate 4TB portable HD
Using it to backup all my videos and photos, so far it hasn't missed a beat, it's replacing my other older smaller HDs and consolidating them onto one.

I was very surprised when I picked up my new hard drive. It was half the size and weight of the previous ones I've purchased. Much easier to store .
