SSD RunCore Pro IVはTRIM機能をサポートしていない(?)

Ubuntu 12.04にバージョンアップしたかったのは、以前にSSDに換装したため、10.04だとTRIM機能がないし・・と思っていたからなんだけど...

12.04を入れただけでは自動設定にはならないらしいというので、ちょっと調べてみると、もしかして対応していないのか?えっ、そんなことって

メーカーの商品特徴(参照)には

Garbage Collection機能内蔵でSSDの弱点であった速度劣化を防止。Trim処理が不要です。

とあったけど、「不要」って、TRIMをサポートしてないって意味なのかな???
 

sudo fstrim -v /
fstrim: /: FITRIM ioctl failed: サポートされていない操作です
