SDカードのベンチマーク

手持ちのSDカードのスピードを調べるべくベンチマークを取ってみました。
調べたのは、Sandisk 2GB 、Toshiba 16GB Class 4 、Team 8GB Class 6 、SilionPower 8GB Class 6 、SiliconPower 16GB Class 10 の5種類。
使用したベンチマークソフトはCrystalDiskMarkです。
おおむねClassが高く、値段が高いものが高速でした。
しかしシリコンパワーのClass 6とClass 10では一部逆転していました。

またdata2whateverやData2extに使用するにはClass 6、Class 10のものが必要でした。
お手持ちのカードが使えるか参考にしてください。
