正好相反....
Fixed Size 在建立時，就佔好空間
沒有 "馬上霸佔好 xx GB" 的是 Dynamically expending
一樣建立 20GB 的 virtual disk
Fixed size 在 host 端一次就佔足 20GB，就算 virtual disk 裡頭都是空的，還是佔 20GB
Dynamic 先佔一點點小空間，做為 metadata 用，通常不過數十~數佰 KByte
當裡頭的增加了 1GB 的資料時，host 端的檔案才會從 xxxkbyte，長到 1.xxGB
(但裡頭的資料從 1GB 刪除成 0 時，host 端的檔案並不會自動縮小)
不過，上限一樣都是 20GB (因為這是原始設定)
二者的優缺點正好互異
Fixed size 好處是減少 fragment，順便增加 disk i/o 效率；但就是佔空間
Dynamic 好處就是節省空間，可在有限的空間切出更多的 virtual disk；但缺點就是容 fragment
