    Hello all,

    I am just wondering what does HD's cache do in plain english? Like 2 MB cache, 8 MB, and rarely 16 MB (only Toshbia I seen this).

    TIA.

    When you make a large request to your HD, the HD can get it and store it in cache. The CPU can do whatever it wants and get it whenever it feels like it. It's a buffer. It's like your HD is a water tap. The CPU is you. When you'r' thirsty, you can drink directly from the tap a few times or you can tie your shoelaces while filling a glass and then take the glass. The cache is the glass. It makes the HD run more efficient.
