    141tb = 144384g

    現在儲存廠家儘管主機板和芯片還是採用二進制算法,但是儲存容量都使用十進制的算法,之前因為這樣也被舉報偷工減料,但當幾乎所有的廠家都這麼做的時候,就變成了行業的默認標準了。 按照2進制的算法: 1TB = 1024 GB = 1048576 MB = 1073741824 B(Bytes) 但現在很多的硬盤,U盤儲存商家採用的 10 進制是: 1TB = 1 GB = 1 MB = 1 B(Bytes) 也就是 1TB 既可以是 1073741824 B,也可以是 1 B,也就是2進制換成了10進制算法,實際容量少了7.37%了。 所以廠家標明的硬盤是 1TB,可能是按照 10 進制計算,也就是 1 B 了,但是安裝到電腦後,由於電腦系統採用的是 16進制(可以看做是2進制的一種算法),系統格式化後會顯示 1 / 1024 / 1024 = 953.67GB 了,這個就是同樣的 1TB 使用了不同的概念所得出的差距了。所以硬盤容量,使用 2進制換算,在 953.67GB 到 1024GB 都可以被標注為 1TB 的硬盤容量。 所以您提到的硬盤容量 1TB 是否是 1024GB,需要看使用的是 2 進制,還是 10 進制了。
