Apple’s iCloud may be a little limited as a cloud storage solution compared to services like Dropbox, but the sheer number of iDevices on people’s hands have already pushed the year-and-a-half old platform to the top among US consumer cloud services. According to a report by Strategy Analytics, out of 2,300 poll respondents, the combination of iCloud and iTunes Match accounted for a 27% usage share.

Dropbox came in second snagging an impressive 17% share considering the company doesn’t have a product ecosystem tied to the service. Amazon Cloud Drive was a close third with 15% while Google Drive holds 10%.

The survey found that cloud storage is particularly popular among people ages 20 to 24 and the most common use for cloud storage is music. Of those surveyed, 90% of iCloud, Amazon and Google Drive users store music files in the cloud. Meanwhile, those with Dropbox accounts appear to have more diverse uses for their cloud storage space, as audio represents a lower (but still sizable) 45% of the content on that platform.

“Music is currently the key battleground in the war for cloud domination. Google is tempting users by giving away free storage for 20,000 songs which can be streamed to any Android device, a feature both Amazon and Apple charge annual subscriptions for,” notes Strategy Analytics’ Director of Digital Media Ed Barton.

Interestingly, a full 55% of those surveyed hadn't used a cloud media service at all, which suggests that there's still plenty of room to grow and users to win over in the world of cloud storage.

It’s worth mentioning that with a polled base of 2,300 people -- all of them in the U.S. -- we don’t expect these numbers to accurately represent actual market share but it should give you a general idea of what’s popular among users. For what it’s worth, Apple announced in January 2013 that iCloud had passed the 250 million user mark, while Dropbox announced in November 2012 that it had reached a milestone of 100 million users. Google and Amazon haven’t shared any official numbers for their respective cloud storage solutions.
