さらに1つ減らして95にすることに成功しました。
やったのはAcronis True ImageによるSSD全体のレストア（ファイル量にして約47.5GB）で、この30回目（約1426GB）の後で95になりました。その前にチェックした28回目（約1331GB）では96だったので、この間の1.4TB前後で変わったことになります。
ただ、今回はなぜかE1も1つ減って199になりました。

そうですねー。おそらく持っている人は相当数いて、その中には関心の高い人もいると思いますが、今回実感しましたが、これだけ書き込まないと変わらないということは、普通に使うだけではめったに変わらないわけで、目を引きにくいのかもしれません。

X25-Mの発表時のintelの資料を見ると、"100GB/day for 5 years"とあるので、
http://pc.watch.impress.co.jp/docs/2008/0820/mobile421.htm
単純計算で、少なくとも178TBの書き込みに耐えるということになると思います。E9の値が初期値99として0まであるとすると、1つ分が1.7TBになりますが、計算が合いません。といっても、どういう条件の書き込みか分からないので、何とも言えませんが。

いずれにしても、他の方の情報もほしいですね。もう80台に突入している人もいるのではないかと思いますし。

>寿命が数字だけでなくメーター表示できるとなお良いかも・・・。

格好よさげですね。他に思い付きですが、命が小さくなっていくようなイメージでもいいかもしれないですね。ハートのアイコンが段々小さくなっていくとか。

では、95になったものを貼ります。
