얼마전에 구입한 삼성 micro sd 카드(class10, 32G)로 간단한 실험을 해보았다.
micro sd 카드를 USB(2.0?) adapter에 꽂았을 때:
~$ sudo hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 1232 MB in 2.00 seconds = 616.46 MB/sec
Timing buffered disk reads: 90 MB in 3.07 seconds = 29.36 MB/sec
micro sd 카드를 SD adapter에 꽂았을 때:
~$ sudo hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 800 MB in 2.00 seconds = 400.17 MB/sec
Timing buffered disk reads: 8 MB in 3.19 seconds = 2.50 MB/sec
happy hackin'
