Although JFFS was very useful in its time, its wear-leveling algorithm tended to shorten the life of NOR flash devices.
尽管JFFS在早期非常有用，但是它的平均读写算法容易缩短NOR flash设备的寿命。
On the other hand, the improvement can enhance the management of wear-leveling algorithm to different types of files in the flash, achieve more efficient wear-leveling.
垃圾回收时在遵照磨损均衡原则的前提下提高写入数据效率，同时增强该算法对不同类型的文件存储单元管理能力，从而达到更加有效的磨损均衡。
