Design and Implementation of High Speed Recording File System Based on ExFAT
As a crucial component of data recording systems,file systems are vital to the performance of high speed recording devices.This paper conducts an in-depth analysis of the file requirements of high speed recording systems and innovatively ex-tends the ExFAT file system to develop a new file system JFAT.JFAT integrates logging function,enhances data reliability and features power-off recovery capabilities,thereby strengthening the stability of the recording system.Additionally,JFAT exhibits good compatibility,supports various mainstream operating systems including Linux and VxWorks,which makes it suitable for being used as a system installation disk.By combining fast read-write channels,TRIM commands and file pre-allo-cation with other hardware and software optimization methods,JFAT fully leverages hardware performance.In practical appli-cations,the data recording module using JFAT achieves a record speed of 7.6 GB/s per module and has been implemented in specific data recording device.JFAT not only improves the efficiency and reliability of file systems but also provides new techni-cal support for the development of high speed data recording devices.
