Fail-safe exFAT driver with no data corruption

Unexpected power interruptions or device unplugs can cause data loss. Our patented fail-safe technology minimizes data corruption in case of a sudden power loss. This means no playback interruptions whether it’s music, movies, photos, or any other file saved on a portable storage device.

Improved exFAT performance and flash lifetime

Get the maximum I/O throughput out of your flash media. Our patented Smart Allocator feature ensures low fragmentation, reduced latency, increased performance, and maximizes the lifetime of inherently short-lived NAND flash.

Optimize hardware costs with data persistence for dashcams

Tuxera Persistence ManagerTM is a premium add-on designed to save super-capacitor costs primarily in dashcam use cases. The feature is configurable and controls how frequently the data is committed to the storage media. It also prevents data loss for Linux- and Android-based recording devices in case of power interruptions.
