General Purpose (SSD)なEBSでベンチマーク

リージョン:ap-northeast-1
インスタンスタイプ:c3large
ボリュームサイズ:8GB
OS:AmazonLinux64bit
AMIID:amzn-ami-pv-2014.03.1.x86_64-ebs (ami-c9562fc8)

fioコマンド2.1.7を使って計測
ベンチマークのパターンはhttp://www.winkey.jp/downloads/index.php/fio-crystaldiskmarkで公開されている
ジョブファイルを利用。

連続して10回実施した結果は以下の通りでした。

取り急ぎまるっと結果だけはってます。
