Re: [問題] nas走內網速度 vs das走usb速度？

※ 引述《j8xx (翻譯官)》之銘言：
: 請問大大們，
: 因為目前在決定要nas還是das，
: 有一個是傳輸速度，大家是說nas傳的慢，但是如果是走內網一樣很慢嗎？跟一般外接硬
這個不好說, 跟錢有關

: 碟走usb的速度比誰比較快？
: 先感謝大大們惹

我的環境如下:
-------------

NAS: QNAP TS-h1277XU-RP 32G
SSD: Crucial MX-500 2TB x6
NIC: LAN-40G2SF-MLX

簡單說就是 6 顆 SSD 做 RAID-6, 透過 40GbE 的網卡傳輸
