Hi, the reason our cost is higher than your USB drive is because our product is BETTER and MORE than a USB drive.
(1) Note our system is much more reliable than a USB drive. We keep duplicate sets of storage for best protection against data loss; so if you have 10GB, on our system, we actually use about 10 + 10 + 4GB (overhead) = 24GB of storage.
(2) We provide download / upload service, which uses a lot of bandwidth;
(3) We host our system in a state-of-the-art Colocation where we lease facility space. The data center offer redundant power supply, redundant network connections, etc. Thus the service is much more reliable than any self-hosted services.
(4) Our product is really better than a USB drive. You can access your data from anywhere, anytime; your data will be safe even if computer crashes, gets hacked, or in any major disaster like theft, fire, hurricane, earthquake, etc, your data will be safe.
Please take a look at our services like: Online Sharing and Collaboration service, Complete FTP hosting service, etc: http://www.drivehq.com/help/features/
DriveHQ is a technology and service oriented company, we have the best technologies and features. If our service doesn't save you time and money, don't pay us. Otherwise, you will find our service very worthwhile. It is even cheaper than USB flash drive. But you know USB flash drive has very limited amount of storage, it doesn't let you share files remotely, and it is plainly not as safe or reliable as our storage.
