Sharing large files can be a pain, especially if you have to carry sensitive data around on a USB drive or worry about the potential security loopholes of storing it on a cloud service. While gimmicky inventions like the vibrating USB drive get us excited for a minute, iTwin has an innovative solution for tackling the security concerns of toting important files on a portable device. The two-part USB drive, which hooks up two computers remotely by transferring files over the Internet, has expanded its file-sharing service to Mac OS X users.
Unlike a USB device that stores data on an actual gadget, iTwin's device only requires the user to install software once. With the plug-in, the user can stick the iTwin into the USB port to share files. When the user wants to take those files to another computer, he has to unplug the "twin" piece of the device and bring it with him from a home computer to a work computer, for instance.
The only requirement is that both computers be connected to the Internet before the files can be sent through military-level encryption. Also, the second piece must physically plug in to the second computer, which adds an extra layer of security. The extra paranoid can set up a password for even more security. If the USB device gets lost, the owner will have the option to deactivate it.
The design eliminates the need to store files in the cloud, essentially creating a personal cloud. While there's no limit to how much information the USB drive can store, its upper limit depends on the primary computer's hard drive.
