Replying to External Hard Drives

Anybody have any suggestions for hard drives?

I've been trying to take into consideration the average lifespan of different drives, transfer speeds (Thunderbolt seems to be the fastest available for my Macbook Pro), and storage size.

I'm fine with 1TB of space, as I'm just using them for storing my photos. Anymore would be overkill considering I typically delete the pictures I'm not too fond of.

Any help would be much appreciated!
