Datalight Outperforms Other Linux Flash File Systems

Posted by: Thom Denholm

It's always gratifying when you run benchmarks and discover your product actually does outperform the competition. Months and months of development effort went in to making Reliance Nitro and FlashFX Tera run flawlessly in an open source environment. We were pretty sure our transactional architecture beat the pants off YAFFS2, JFFS2, and UBIFS, but until you run the final benchmarks, you really don't know for certain. Recently we ran tests on two platforms, a ConnectCore Wi-i.MX51 (Cortex-A8) and an NVidia Tegra 2 (Cortex ARM9). The Flash part used for all tests was a Samsung 512 MB part. The specific test used was IOZone, with a specified file size sufficient to be larger than the Linux cache, in order to better reflect the raw throughput. The results speak for themselves:
