A term used to indicate the number of disk drives built into a computer. Hard disks, floppy disks, CDs, DVDs, and other drives built into a computer all have disks that rotate around a "spindle," so the total number of drives built into a computer is called "two spindles" (when a hard disk and a DVD-ROM drive are built in, for example) or "three spindles" (when a floppy disk, hard disk, and DVD-ROM drive are built in, for example). Currently, the minimum configuration is a "one spindle" with one hard disk built in to run the OS (basic software) and application software and to store data, but if the hard disk is replaced with an SSD that uses large-capacity flash memory, there will be no "rotating disks," so it will become a "zero spindle." Some manufacturers have already released "zero spindle computers" as special models of mobile computers with excellent portability.

パソコンに内蔵されたディスクドライブの数を示す際に使う言葉。ハードディスク、フロッピーディスク、CDやDVDといった、パソコンに内蔵されるドライブはいずれも「軸(スピンドル)」を中心に円盤が回転するものであるから、これらのドライブが合計何台内蔵されているかを「2(ツー)スピンドル」(ハードディスクとDVD-ROMドライブを内蔵する場合など)、「3(スリー)スピンドル」(フロッピーディスク、ハードディスク、DVD-ROMドライブを内蔵する場合など)などと呼ぶ。現状ではOS(基本ソフト)やアプリケーションソフトの起動とデータ保存に利用するハードディスク1台を内蔵する「1スピンドル」が最小構成となるが、ハードディスクを大容量フラッシュメモリーを利用したSSDに置き換えると「回転するディスク」が皆無となるため「ゼロスピンドル」になる。既に一部のメーカーが、携帯性に優れたモバイルパソコンの特別モデルとして「ゼロスピンドル・パソコン」を発売している。
