Phast 1G SD & 리더기 성능 TEST ^^;

산드라 결과는 WiSi님이 올려주셨기에 생략합니다...

한가지 덧 붙이고자 하는것은 벤치결과는

SD의 속도보다 때로는 메모리리더기가 더

중요할 수 있다는 것이지요.

간단히 TEST한 결과로는...


100MB의 단일화일 전송 결과입니다.

I-Rocks - Write : 15초

               Read : 8초

ELLA      - Write : 27초

                Read : 10초


950MB의 짬뽕화일 전송 결과입니다.

I-Rocks - Write : 4분07초

               Read : 2분18초

               Delete : 56초

ELLA      - Write : 5분54초

                Read : 3분24초

                Delete : 56초


I-Rocks 멀티리더기는 기존에 가지고 있던것이고

ELLA는 이번에 공구한 제품이랍니다.

산드라 결과도 I-Rocks으로 하면 엄청난 차이가 있지요 ^^

ELLA는 휴대용으로만 써야 겠다는 생각을 하게 만드는 결과였습니다.

그럼 이만...

참... RW6100에서의 TEST결과도 올립니다.

이건 스크롤 압박이니 PASS하셔도 좋습니다.

 		읽기가 쓰기보다 너무 빠른 건 먼저 쓴 후에 읽으셨기 때문일 겁니다. 어딘가에 저장해 놓는지 한번 썼던 놈은 SD에서 하드로 가는 것이 아니고 Ram에서 하드로 가는 듯 하더군요. 100메가 짜리 화일을 SD에 저장해놓고 컴퓨터 껐다가 다시 하드로 옮기면 10초 이내에 읽지는 못할 듯 합니다.

211.210.189.116 		그래서 저장장치 읽기 테스트를 할 때는 항상 한번 하고 재부팅하고 다시 해야 하죠. 그렇지 않으면 두번째 한 것이 좋은 결과를 보여주죠. 100M를 8초에 읽으면 초당 전송률이 10M/S를 넘게 되죠.

 		그렇군요 ^^ 읽기 테스트에서 오류가 있었네요... 아이락으로 지금 다시 TEST해보니 쓰기와 동일하게 15초가 걸리는군요. 쓰기 테스트야 캐시속도나 하드속도가 SD속도보다 빠르니 별 문제가 안될것이고... 읽기 테스트는 다시해야 겠으나... ^^; 그냥 리더기 성능도 중요하다는 딴지 정도로만 봐 주시길~~~ ^^

 		참고로 이건 I-rock에서 산드라 돌린 수치랍니다.

용량이 커질수록 읽기와 쓰기 속도가 비슷하게 나오네요
