hdparm 小测:

/dev/sda:
Timing cached reads:   3156 MB in  2.00 seconds = 1578.06 MB/sec
Timing buffered disk reads:  142 MB in  3.01 seconds =  47.20 MB/sec
/dev/sdb:
Timing cached reads:   3098 MB in  2.00 seconds = 1548.47 MB/sec
Timing buffered disk reads:  124 MB in  3.05 seconds =  40.71 MB/sec
/dev/sdc:
Timing cached reads:   3220 MB in  2.00 seconds = 1609.79 MB/sec
Timing buffered disk reads:  422 MB in  3.00 seconds = 140.64 MB/sec
看来十几年了 ,机械硬盘也就提速3倍左右。
hd turn 测试:
最廉价的硬盘竟然和WD黑盘/RE4 差不多 ,性价比真的很高。
