好幾年沒碰電腦的新玩意，最近才又重新開始，發現好多連聽都沒聽過的東西
最近更新電腦的古董配備，加上了一顆intel 330 120G SSD
搜尋之下知道它的控制晶片有壓縮資料再寫入flash的中間動作
因此出現了一個疑問
分割區對齊這件事是讓NTFS 4K block和flash存取單位能夠一個蘿蔔對應一個蘿蔔坑吧？
那原來在NTFS上16K/佔4K x 4的資料
經過sand force chip的壓縮後，
到了flash上，可能是11K，13K，也可能是不到1K(那種填入全0連續資料的)
這樣NTFS上的一個4K，還能映對flash上的一個4K嗎?
稍微google一下，使用關鍵字"sand force 對齊 壓縮"看到多半是介紹文和測試文
題外話
有個生產音響的朋友，往來台灣大陸，還有電路設計工作都在一台筆電上，
除了抓來的影片存在外接磁碟上
今天問他2010年買的intel 80G SSD健康度，他傳圖片過來，健康度和壽命都還是滿的
不知道該幫他慶賀還是intel程式有盲點
