The company says over 70 terabytes are synced via the tool every day. BitTorrent first announced its Sync software back in January and released a private alpha. Between then and April 23, when the company release a public alpha, users synced over 200TB worth of data. In other words, over the past 13 days users have synced over 800TB of data. At this rate, the service will pass 10PB before even hitting a stable release.
