답변1

짧은 버전:

당신의인텐소 외장 SSD고성능 모델을 구입했다면 이미 최고의 성능을 달성한 것입니다. 그러나 최고급 성능 모델을 구입하는 경우 다음을 수행해야 합니다.

  1. 먼저 다른 USB3.1 케이블을 사용해 보세요.
  2. 케이블 문제를 해결한 후 제조업체에 문의하세요.

긴 버전:

  1. 모든 USB 케이블은 동일하지만 일부는 다른 케이블보다 더 동일합니다.

    USB 2.0 레이아웃:

    Pin     Colour      Name    Description
1       Red         VCC     +5 VDC
2       White       D-      Data -
3       Green       D+      Data +
4       Black       GND     Ground

    USB 3.x 레이아웃:

    Pin     Colour              Name                Description
                A connector     B connector
1   Red                     VBUS                Power
2   White                   D−                  USB 2.0 differential pair
3   Green                   D+
4   Black                   GND                 Ground for power return
5   Blue        StdA_SSRX−      StdB_SSTX−      SuperSpeed receiver differential pair
6   Yellow      StdA_SSRX+      StdB_SSTX+
7   N/A                     GND_DRAIN           Ground for signal return
8   Purple      StdA_SSTX−      StdB_SSRX−      SuperSpeed transmitter differential pair
9   Orange      StdA_SSTX+      StdB_SSRX+

    따라서 케이블이 손상되었거나 잘못된 케이블이 있는 경우 케이블을 교체해야 합니다. 그렇지 않으면 USB 2.0으로 돌아갑니다.

  2. SSD의 두 가지 주요 부분은 컨트롤러 브리지와 실제낸드 게이트작은 조각. 당신에 관한 한,지능형 마이크로컨트롤러 브리지예유능한~의초고속하지만 SSD의 실제 NAND는오직고속테스트 결과에 따르면.

    SuperSpeed와 고속 NAND의 차이점은 무엇인가요?

    따라서 (소형) USB 스틱에는 SuperSpeed ​​지원 컨트롤러와 NAND가 포함되어 있지만, (대형) SSD에는 SuperSpeed ​​지원 컨트롤러만 포함되어 있고 그에 맞는 NAND는 포함되어 있지 않습니다.

    많은 정보를 제공해주셨지만 SSD의 실제 모델번호는 알려주지 않으셨기 때문에 Intenso가 자사 웹사이트에 USB ID를 공개하지 않기 때문에 최고 성능 모델이 아닌 고성능 모델을 구입하셨는지 확인할 수 없습니다. . 일반적으로 최고 성능 모델은 고성능 모델보다 가격이 2배 더 비싸므로,만약의 경우에최고 성능의 모델을 구매하셨으나 제조사로부터 혼선이 있어 해당 제조사에 연락하여 교체를 요청하셔야 합니다.
