Do you guys have any recommendations for a portable hard drive? My laptop only has 250GB and is already 160 full. I want to get an HDD specifically for storing images for when I acquire my first DSLR. I will probably be shooting Fine JPEG at first but plan on shooting RAW when I decide to delve into editing. Maybe even JPEG+RAW. Looking for something durable with good write speed(of course). I'd say 250GB minimum. Anyone have any advice?
