RamDisk nedir ve nasıl kullanılır?

Nedir?
RAMDisk, eski tip mekanik hard-disk-lerin okuma ve yazma hızlarının düşüklüğünden bir nebze kurtulmak için kullanabileceğiniz faydalı bir yazılımdır. :) Kısacası; bu yazılım ile bilgisayarınız, fiziksel disk yerine (hard-disk) hali hazırdaki RAM-lerinizi (sanal) disk olarak kullanır.

Kullanımı
Basitçe, tanımladığınz sanal partisyon dizinine çok sık kullandığınız bir programı kurduktan sonra bilgisayarınızda belirgin bir hız artışı sağlanabilir.

Örnek
Google Chrome'da kullanımı;
Web Tarayıcısının, diske kullandığı dizini, yeni tanımladığınız sanal diske ayarlamanız ve aşağıdaki örneğe bakarak yeni bir kısayol tanımlamanız yeterlidir.
"C:\Program Files\Google\Chrome\Application\chrome.exe" --user-data-dir="G:\chrome_userdata"

-- G:\chrome_userdata; sanal disk dizini
