SanDisk has somehow managed to fit 128GB of storage into an updated version of its miniscule Ultra Fit USB 3.0 flash drive. The device, almost no larger than its USB connector, can easily take residence on your keychain, offering USB 3.0 transfer speeds of up to 130 megabytes per second. It also comes with a 5-year warranty, SecureAccess software for creating a password-protected 128-bit AES encrypted folder, and one year of free access to the SanDisk RescuePro file backup service. And while portability is the main selling point, users may find its best use as an instant storage boost for their ultra-thin laptops. Look for the $120 flash drive to arrive soon at retailers.
