    FlashFX® Tera is a flash memory manager (FTL) that frees developers from the volatility and constraints of a single-source flash memory driver while handling wear leveling, bad block management, and other vulnerabilities of NAND flash memory. Versatility allows fast integration with over 300 flash chip part numbers.

Latency vs. Throughput: Perspectives in Measuring File System Performance

A Short History of Embedded File Systems Embedded devices such as mobile phones, digital cameras, and set-top boxes, and the operating systems upon which they rely have evolved dramatically over the last ten years.

Consider that ten years ago the vast majority of embedded devices did not use file systems. The rise of NAND flash, with its higher densities, and more deterministic performance characteristics (as compared with NOR flash), has satisfied consumer demands for more storage. Whether using raw NAND with a flash media manager such as Datalight’s FlashFX, or managed NAND such as SD cards and e•MMC, NAND flash has become the de-facto standard for storage media in portable embedded devices.

Likewise, consider that 10 years ago, today’s “big three” operating system vendors for mobile phones (Google, Apple, and Microsoft), had zero presence, not only in the mobile phone market, but virtually zero presence in the entire embedded space.

Finally, ten years ago, any embedded device which included a file system was a bit unusual to start with; one with a multithreaded file system was pretty much unheard of. Today it is common for a typical smartphone to have hundreds of active threads in the system, many of which are doing file system I/O.
