Dropbox pioneered cloud storage and its sync technology remains the fastest in the industry.

Frequently Asked Questions
Editor's Take
I use Dropbox for work files and Sync.com for anything personal or sensitive — tax documents, legal papers, health records. That split says everything about this comparison. Dropbox is faster and more polished, but knowing that Sync.com literally cannot read my files gives me peace of mind that no amount of Dropbox polish can match. If you only want one, ask yourself: do I care more about speed or privacy?
