열어보니 생각외로 작다라는 느낌인데.. 신용카드랑 비교해봐도 확실히 작다 (규격상 폭이 34mm 니까..)
옛날.. PCMCIA 생각하면 2/3 정도 크기 될 정도?
그나저나 이거 어떻게 빼지? USB 처럼 안전 제거 없나?!
그 와중에 의외로 많이 튀어 나왔다.
처음에는 뻑뻑해서 그랬나 모르겠는데, 몇번 하니 딸깍 하면서 들어갔다 걸리는 느낌이 조금 나긴 한다.
항상 꽂아 놓고 쓰면 모를까.. 휴대하려면 빼고 다녀야 할 듯.
리눅스(우분투 22.04)에 연결하니 바로 인식된다.
물리적으로는 USB3.0 * 2인데 뜬금없이... USB 2.0 root hub는 왜 생긴거지?
