Security:  

SugarSync is indeed a secure online storage and sharing solution. During the transfer/sync process of uploading and downloading files, SugarSync utilizes SSL (secure socket layer) encryption. And while the files are being stored on secure servers, SugarSync keeps them protected with 128-bit AES (Advanced Encryption Standard) encryption. Furthermore, their servers are backed up redundantly in multiple data centers.

Your account and personal access webpage are password protected. You can even require that others who you allow access to the files via an emailed link have to input a special access code.
 

Storage Space/Price:  

Not only does SugarSync offer a unique combination of features, the service is available at a valuable price. You can try the service for free for 45 days with up to 10GB of storage. There are several purchase options, ranging from the basic plan (30GB) for $4.99 a month, to the Business plan (250GB) for $24.99 a month. The other options are the Premium Plan (60GB) for $9.99 and Professional Plan (100GB) for $14.99.

Each plan is available for purchase on a monthly basis (prices noted above), but you can also save some money by purchasing for the year and getting 12 months for the price of 10. For example, the $9.99 Premium Plan can be purchased for a full year for $99.99.
With competitive prices and flexible sizing, SugarSync offers their amazing service at a similarly great price.
