About a year ago, we switched from DropBox to Microsoft's OneDrive (formerly SkyDrive) primarily because OneDrive had evolved to pretty well match all of the core functions of DropBox but offered substantially higher levels of storage on all tiers, free and paid. As of this writing, OneDrive provides you with 15 GB of free storage while DropBox provides only 2 GB (you can increase both limits in 0.5 GB increments with referrals to other people you know). Additionally, if you install OneDrive on your smartphone and turn on the "Camera Roll" function (more on that below), you'll get an additional 3 GB of storage space. Need more space? OneDrive gives you 100 GB for $1.99 per month, 200 GB for $3.99 per month, and a whopping 1 TB for $6.99 per month (this is actually part of the Office 365 Personal subscription service). By contrast, DropBox's only other individual price tier provides 1 TB of storage for $9.99 per month (and this obviously doesn't include any of the goodies from an Office 365 subscription).
