U3測試 SuperTalent ST4/Apacer AH350 - 儲存設備

這次測了兩支USB 3.0 dongle:
1. Super Talent ST4 64G
號稱4ch的dongle
2. Apacer AH350 16G
號稱...最輕的usb 3.0 dongle
不囉嗦..直接上數據

4K QD 32接在 NEC反而測不完, 會當掉..
懶得去找原因. 數據跟樓上I公司原生非常接近.

一分錢一分貨, 尤其是512K以下的寫入性能根本叫做不同次元.
不過兩隻都被老老的Kingston DTU30 G1 32G電..(Storage_Zone #1DrHB3O1)

目前這些所謂單晶片的U3碟, 小檔案寫入能力看起來都蠻糟糕的.
像是常見的黑鷹, 貴森森的Kingston HyperX, 上面這支號稱4ch的ST4已經有好一點點,
但是還是稱不上強悍...甚至打不贏前一代雙晶片兜起來的方案..

這樣不就只是cost down了嗎..>_<

Host controller 部分,I公司的產品看起來跟NEC上代產品差不多.
不過也許是這兩隻dongle都還無法測出host controller真正的實力吧..

下次目標:
號稱變態的Super Talent RC8 50G..
