※ 引述《rwhung (iceman何時露GG)》之銘言:
: *1 RAMDISK的用途: 主要'用記憶體取代硬碟,提升讀取速度
: 次要'反正主記憶體用不到(32位元版只用到3.X),不用白不用
: 虛擬記憶體的用途: 主要'用來取代主記憶體的不足
: (即分頁檔) 通常設為主記體的1.5-2.5倍,超過的話效能不見得提升
: RAMDISK比較適合的地方: A.常用的資料夾或檔案(必須注意回存)
: B.有些程式所存放在硬碟的暫存檔
: C.映像檔
: D.略...這好像不是我的功課....
個人之前在win7使用ramdisk時,有一點一直讓我很困擾,所以最後還是移除ramdisk
ramdisk快歸快,裡面的內容終究還是要從硬碟讀進去
因此在開機時會嚴重拖累開機速度,並影響開機時的操作流暢度
關機時也會影響
(傳統硬碟讀取算每秒120mb好了,讀個4g的ramdisk保守估計就要30~40秒)
後來用win8享受8秒神速開機之後,也不太想再去嘗試ramdisk了
ramdisk大概只對重度遊戲者把最常玩的遊戲灌進去會有明顯效益
不然就是設成photoshop暫存,然後把ramdisk設定成開關機不回存
這樣比較不會影響開關機
