いろいろメモ: 6月 2016

NTT-Xストアにてクーポン割引でどちらも5780円でしたので、両方買ってみました。さて両者を比較してみると・・・

・Silicon Powerはカバー両面が金属製、
・CFDは写真の通り表側が安っぽいプラスチック。

CDFの方が放熱が弱いため、寿命が短くなる可能性があるかも。ただ、実際の発熱具合を比較してないので、何ともいえません。

データRead/Writeの比較ですが、まとめると以下のようになりました。

50MB, 1GBのRead/Writeは殆ど同じ。
16GBのWrite時間はSilicon Powerの方がSequentialで3倍遅くなった
。

ということで、CFDの勝ちですかね。大きなデータのやりとりしなければ、Silicon PowerでもOK。

詳細は以下になります。測定環境はOSがWin10以外はいつもと同じ(Corei7 3820/56GB)。

RW	Silicon Power S55	CFD CSSD-S6O240
50MB
1GB
16GB
Info

Silicon Powerの16GBで遅くなるのは、サイズが大きいために書き込みバッファで対応しきれない様子です。
