## Jazz Disk Bench Pro - 측속 Description
Jazz Disk Bench는 SSD, SD 카드, 내부/외부 저장소를 위해 설계된 전문급 저장소 성능 측정 도구입니다. 업계 표준 테스트 방법으로 기기의 처리량을 정확하게 측정합니다.

주요 기능：
* 순차 속도 테스트：대용량 파일(영화, 게임 등) 복사 시 최고 성능 측정.
* 4K 랜덤 IOPS：시스템 반응성 평가. 랜덤 성능이 낮으면 기기 지연의 근본 원인이 됩니다.
* 프로 스트레스 테스트：2GB~100GB 테스트로 캐시 소진 후 안정성과 '실제' NAND 속도 확인.
* 외부 저장소 지원：USB 드라이브와 SD 카드 완벽 호환.

테스트 세부 정보：
* 순차 테스트：16MB 블록을 순차적으로 읽기/쓰기. 원시 전송 속도 테스트에 완벽.
* 랜덤 테스트(4K)：무작위 위치에서 4KB 블록 읽기/쓰기. OS가 앱을 실행하고 작은 파일을 처리하는 속도 반영.
* 스트레스 테스트：대량 데이터(최대 100GB) 순차 쓰기. 전문 사용자가 SLC 캐시 크기와 지속적인 NAND 쓰기 성능 테스트에 적합.

참고：외부 저장소 테스트 시 안정적인 연결과 쓰기 권한을 확인하세요.
