Amazon thinks it has a way to entice you away from the likes of Dropbox or Google Drive: real, honest-to-goodness unlimited internet storage. It just launched two Cloud Drive plans that let you upload as much as you like, with the primary difference being what you can upload without worrying about caps. If you're only interested in preserving photos, an Unlimited Photos Plan costs a modest $12 per year, or free on Prime; you'll have 5GB to use for anything else. Should you have a lot of documents or a sizable video collection, an Unlimited Everything tier will cost a still-pretty-reasonable $60 per year. The one catch is that there's no truly free option. You can get a 3-month free trial, but you'll want to look at the no-cost alternatives if you don't expect to store gobs of files online.
