Hobbiest here.
I import to a folder on my desktop, run the photos through photo mechanic for culling/sorting, and transfer a NAS for long term storage. The NAS syncs with OneDrive using the 1 TB that comes with office 365. Haven't run into the limit yet, but when I do I'm not completely sure what I'll do.
I'm going to attempt culling and sorting via iPAD, but I'm kind of dubious that it will be anywhere as fast a photo mechanic. If anyone is already going the iPAD I'm interested in hearing what software you're using.
