艾客優品AKiTiO NT2 U31C鐵甲威龍 3.5吋 USB 3.2 Gen2 2Bay磁碟陣列外接盒-操作簡單輕鬆備份
https://i2.wp.com/3cjohn.000webhostapp.com/title.png操作簡單輕鬆備份
近年來資料備份意識崛起，許多使用者了解資料備份的重要性，資料備份方式從簡單的USB隨身碟/隨身硬碟到複雜的NAS系統，USB隨身碟/隨身硬碟雖然方便，但沒有RAID功能還是會有資料損毀的風險，而複雜的NAS系統雖然功能強悍，但持有成本相對高很多，且必須透過網路方式存取(主流網路速度1Gbps傳輸率約125MB/s)；這次要介紹可透過USB3.2 Gen2存取的備份方案，由艾客優品AKiTiO推出的『NT2 U31C』鐵甲威龍 3.5吋 USB 3.2 Gen2 2Bay磁碟陣列外接盒，NT2 U31C採用USB 3.2 Gen2作為傳輸介面，最高傳輸速路為10Gbps，是網路速度的10倍，只要有 Thunderbolt 3與USB Type-C的電腦皆可使用，且支援UASP加速模式，可安裝兩顆3.5吋硬碟，且體積縮到最小，外殼採用金屬鋁材並內建風扇，可提高硬碟的散熱效果，單顆硬碟容量支援80GB~12TB，RAID模式支援Non-RAID、RAID0、RAID1與SPAN，使用者可依照使用環境與需求調整，系統支援Windows7以上或macOS 10.12.4以上版本，重點是操作相當簡單，選取完RAID模式後就設定完成即可開始使用，現在就來看艾客優品AKiTiO NT2 U31C鐵甲威龍 3.5吋 USB 3.2 Gen2 2Bay磁碟陣列外接盒帶來的效能表現啦。

艾客優品AKiTiO NT2 U31C鐵甲威龍 3.5吋 USB 3.2 Gen2 2Bay磁碟陣列外接盒真的是款非常方便的產品，透過後方的RAID模式切換，可輕鬆快速切換RAID模式，使用者可搭配各種不同環境使用，效能表現方面RAID0雖然表現較佳，但會使用這個模式的人應該不多，畢竟少了備份的主要功能，RAID1雖然只有單顆硬碟效能，但多了硬碟任意可壊一顆的特性，讓資料多一份保障，NT2 U31C可透過USB Type-C與Type-A介面，且支援UASP模式，讓效能可以發揮到最佳狀態，若採用兩顆SSD固態硬碟相信會有更不錯的效能表現，目前USB 3.2 Gen2傳輸介面越來越普及，擁有最高10Gbps的傳輸速率，讓資料備份可以更為快速且方便容易，想找一款採用USB 3.2 Gen2 Type-C且擁有RAID功能的備份外接裝置，相信艾客優品AKiTiO NT2 U31C鐵甲威龍 3.5吋 USB 3.2 Gen2 2Bay磁碟陣列外接盒是個相當不錯的好選擇。
