Fragmented files accumulate over time in the Windows file system. This is due to the fact that the operating system sequentially fills the free disk space when writing files. Free disk space, which appears when old files are deleted, can be located in different parts of the disk; therefore, each file can be split into many fragments. When reading or writing such a file, the hard drive head must constantly move, which reduces the read/write speed and causes mechanical wear of the disc.
AxxonSoft has developed its own file system SolidStore especially for storing video archives. The system is installed on a blank physical or logical drive, which is fully allocated to Axxon Next video archive. In developing SolidStore, it was taken into account that recording will only be sequenced in one direction (looping mode), and the newest data is written in place of the oldest. By optimizing the reading/writing process we managed to minimize the travel of the hard disk head along its surface and to achieve three important advantages:
SolidStore relieves the user from the need to periodically stop the video surveillance system and run the Disk Defragmenter tool. This significantly increases video surveillance uptime and the protected facilities remain under the watchful eyes of the security personnel.
If it is not possible to allocate a separate disk for Axxon Next video archive, it can be written as a regular file in the existing Windows file system.
