测试一下LS Pro下面各种设备的读写速度

1.  4G微硬盘 USB1.1 ：
root@LS-GL7D6:~# hdparm -Tt /dev/sdb1
/dev/sdb1:
Timing cached reads: 236 MB in 2.01 seconds = 117.41 MB/sec
Timing buffered disk reads: 6 MB in 4.02 seconds = 1.49 MB/sec
2.  2GB USB2.0 U盘：
root@LS-GL7D6:~# hdparm -Tt /dev/sdc
/dev/sdc:
Timing cached reads: 220 MB in 2.00 seconds = 110.00 MB/sec
Timing buffered disk reads: 20 MB in 3.48 seconds = 5.75 MB/sec
3.  内置SATA硬盘，Seagate ST3160815AS
root@LS-GL7D6:~# hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 232 MB in 2.00 seconds = 116.00 MB/sec
Timing buffered disk reads: 36 MB in 3.00 seconds = 12.00 MB/sec

4.  2G SD卡+飚王USB2.0读卡器
root@LS-GL7D6:~# hdparm -Tt /dev/sdc
/dev/sdc:
Timing cached reads: 210 MB in 2.00 seconds = 105.00 MB/sec
Timing buffered disk reads: 20 MB in 3.19 seconds = 6.27 MB/sec

同时后台运行mldonkey和transmission，CPU负载在0.6左右，测试数据可能有些偏低。
