代码: 全选
/dev/sda: #local
Timing cached reads: 952 MB in 2.00 seconds = 475.79 MB/sec
Timing buffered disk reads: 108 MB in 3.05 seconds = 35.44 MB/sec
/dev/sdb: #usb2.0
Timing cached reads: 924 MB in 2.00 seconds = 461.57 MB/sec
Timing buffered disk reads: 68 MB in 3.07 seconds = 22.18 MB/sec

no security measure is worth anything if an attacker has physical access to the machine
