Reliance Nitro Linux Filesystem Competitive Comparison

Tuxera Reliance Nitro is a transactional file system created specifically to protect critical system and user data from corruption in embedded devices where power loss may occur. It ensures rock-solid data reliability while providing the performance to deliver an optimal user experience, and it works with a broad array of storage media – including flash memory, RAM, hard disk, USB mass storage, SD/MMC, e•MMC and UFS– and virtually any 32-bit or 64-bit operating system.

Market leading Linux-based devices strive to provide the best user experience possible. Choosing the file system that provides the most reliable, consistent and fast operation can make the difference between user delight and user frustration. You know your system best and this comparison is designed to help you gain perspective on the advantages offered by Reliance Nitro that could help you achieve your goals.
When testing an embedded flash file system for performance, it is important to consider data beyond just reads and writes.

Faster Mount Times

Because Reliance Nitro always maintains a "known good state," it has a mount time advantage particularly after power loss. In situations where there is random I/O penalty, such as in Hard Disk Drives and e•MMC, this advantage is magnified. Journaling file systems such as ext3 and ext4 will need to perform random reads to build the journal. Since Reliance Nitro always keeps the disk in a known good state, there is no need to run integrity checks during the file system boot, even after a disorderly shutdown.



Reliance Nitro is architected to write to the media only when required, providing an improvement in the endurance of the underlying flash media. In these tests we monitored the number of erases required by the FSIO Test, which measures flash file system I/O. With the default configuration, Tuxera’s solution erases 70% less than the ext4 file system on Linux.
