SolidStore 파일 시스템에 대한 일반 정보

Windows 파일 시스템에서는 시간이 지남에 따라 파일이 조각화됩니다. 이는 운영 체제가 파일을 작성할 때 순차적으로 남은 디스크 공간을 채우기 때문입니다.

오래된 파일이 삭제되면 생긴 여유 디스크 공간은 디스크의 다른 부분에 위치할 수 있으며, 따라서 각 파일은 여러 조각으로 나눠질 수 있습니다.

이러한 파일을 읽거나 쓸 때 하드 디스크 헤드는 계속해서 이동해야 하므로 읽기/쓰기 속도가 느려지고 디스크의 기계적 마모가 발생합니다.

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 One video archive (see Creating archives). 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:

• Enable high read/write speeds, approaching the physical access speed limit of the hard disk.
• Increase the service life of the hard disk.
• Solve the problem of data fragmentation: as data is written only in looping mode, fragmentation is minimal and does not accumulate with time. This way, the read/write speed remains high throughout the operation of the video surveillance system.

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 One video archive, it can be written as a regular file in the existing Windows file system.
