意外にもAMDのCPUですね。
この型番で検索すると、HPのSL335sというスケールアウト環境向けサーバがよくヒットするので、DCにはこれらがずらりと並んでいる姿を想像してしまいました。

hdparm
AWSと同じくプランに応じてI/O性能に制限をかけているのでしょう。

# hdparm -tT /dev/sda
/dev/sda:
 Timing cached reads:   5920 MB in  2.00 seconds = 2965.53 MB/sec
 Timing buffered disk reads:   38 MB in  3.13 seconds =  12.14 MB/sec

# hdparm -tT /dev/sdb
/dev/sdb:
 Timing cached reads:   5612 MB in  2.00 seconds = 2810.77 MB/sec
 Timing buffered disk reads:  642 MB in 134.84 seconds =   4.76 MB/sec

/dev/sdbの書き込みがとても速いのですが、Read性能と釣り合いませんね。
