はじめまして。
CDIを利用していて非常に気になる状況が発生しておりますので相談に参りました。
具体的にはタイトル項目のとおりであります。
ホスト書き込み量に対してNAND書き込み量が現時点で約50倍（というか、この項目だけどんどん数字が伸びていっている状況です）というのは明らかに異常な数字であります。
当方のM5Pは一度初期不良により交換しているのですが、交換となったドライブでも同じような現象があり、当初は故障によるものかと思っていたのですが、交換となったドライブでもこれでは果たしてこれは仕様なのかバグなのか判断がつかない状況であります。
この項目に該当するSMARTの値は存在しないようで、Plextool（公式診断ツール）でもこの項目に該当する項目は無いのですが、一体何を元に算出している数字なのでしょうか？
