Overview and history
Datalight was founded in 1983 by Roy Sherrill, a former
CardTrick was announced in 1993 to support the
The first of four patents to eventually be assigned to Datalight, "Method and apparatus for allocating storage in a flash memory",[12] was awarded in 1999, followed up with an additional FlashFX-related patent, "Method and system for managing bad areas in flash memory",[13] in 2001.
In 2003, Reliance, a reliable transactional embedded file system, was released; a related patent, "Reliable file system and method of providing the same",[14] was awarded in 2007.
In 2009, Datalight released FlashFX Tera to support the growing size and complexity of
In 2013, another file system related patent, "Method and Apparatus for Fault-tolerant Memory Management"[15] was issued.
In June 2019, the Finnish storage software and networking technology company Tuxera signed an agreement to acquire Datalight.[16]

Reliance family
Reliance
First released in 2003, Reliance is an embedded file system[17] designed for applications with high reliability requirements.[18] Key features:[19]
- Provides immunity to file corruption, including after unexpected system interruption (e.g., power loss), via atomic transaction points.
- Does not need to check disk integrity at start-up, meaning a shorter boot time.
- Dynamic file system configuration for performance optimization.
- Full data-exchangeability with Microsoft Windows, via the Reliance Windows Driver.
Reliance has a maximum volume size of 2 TB and a maximum file size of 4 GB.[20]
Reliance Nitro
Released in 2009, Reliance Nitro is a file system developed from Reliance; it improved on the performance of original Reliance, primarily by adding a tree-based directory architecture facilitating faster look-ups. The maximum volume size on Reliance Nitro is 32 TB; maximum file size is constrained only by free space.[21]
Reliance Windows Driver
Datalight provides Windows drivers for both Reliance (Reliance Windows Driver; RWD) and Reliance Nitro (Reliance Nitro Windows Driver; RNWD); they provide exchangeability between Reliance-formatted media and Microsoft Windows. Both support Windows Vista and Windows XP; an older version of RWD supports Windows 2000. The drivers are bundled with tools to format media and a utility to check file system integrity.
FlashFX
Introduced in 1995, FlashFX is a flash media manager which allows applications to access flash memory as if it were a hard drive,[17] abstracting the complexity of flash media.[22][23] FlashFX operates either NAND or NOR flash and supports numerous flash devices.[24][25] It can be used with any file system.
Versions:
- FlashFX Pro: Supports around 200 flash chip part numbers and flash arrays up to 2 GB.Windows CE, VxWorks, Nucleus PLUS, and ThreadX.[27] FlashFX Pro is available for Windows Mobile (FlashFX Tera is not).[26]
- FlashFX Tera: Supports around 300 flash chip part numbers and flash arrays up to 2 TB. Has pre-ported versions for Linux, Windows CE, and VxWorks.[28] FlashFX Tera supports MLC NAND flash,[29] while FlashFX Pro does not; another improvement is Tera's error correction, which is more robust than Pro's.[26]
Products using FlashFX include Arcom's PC/104 computer,[30] Curtis-Wright's Continuum Software Architecture,[31] Teltronic's HTT-500 handset,[32] and MCSI's PROMDISK disk emulator.[33]
