雖然說隨著儲存需求的提升,大家對於NAS已經有不少的概念,但多數人對於NAS可能還停留在那裝著3.5吋硬碟的笨重機器。現在NAS在配置、設計上都有大幅的進步,低噪音的無風扇設計,還是更輕巧的2.5吋NAS都是常見的機種。這次介紹的則是以無風扇低噪音為賣點的QNAP HS-453DX,不僅是無風扇設計,在網路埠的部分還搭載了高速的10GbE網路,讓你區域網路內的傳輸更加快速。

愛拍照就需要NAS

NAS是Network Attached Storage的縮寫,直接翻譯就是網路儲存裝置。在過往資料量沒有這麼大的時期,其實靠著電腦備份照片、資料就已經很足夠。但現在4K影片、大量高解析度照片塞滿你的運動攝影機跟手機,沒有個安全的地方備份跟存取實在很不方便。而且現在家用NAS選擇也多很多,不僅有不少2.5吋的迷你NAS,還有外型好看或是低噪音的設計,都讓這裝置放在家中不會太突兀。

低噪音、無風扇設計適合家用

HS-453DX外觀像是個薄型的藍光播放機,頂蓋是大面積的鋁合金面板,除了增加外型設計的分數外,還有個作用就是「散熱」。NAS本體的散熱並不靠風扇,使用的是無風扇設計,內部的處理器、晶片組散熱怎麼辦?答案是靠散熱片的被動散熱,而這大面積的金屬頂蓋,就是散熱片的延伸,靠著低發熱量的晶片與大面積散熱片達到無風扇散熱。

沒有了風扇最直接的影響就是少了噪音,這類小型NAS過往為了散熱安裝的風扇大多受限於體積,風扇葉面較小必須提高轉速才能達到一定的散熱效果。省去了風扇自然就沒有風扇運轉的噪音,還多了個附贈的優點那就是「免清潔」,不須要幾個月就打開NAS清潔風扇,算是省去不少麻煩。最後則是個迷你的優點,那就是少了風扇耗電量少了一些些,算是不無小補。

也因為沒了風扇的噪音與共震,許多人會把NAS做為家裡的Roon Server串流伺服器,相較大部分可串流 Roon Server NAS 的箱型設計減少許多共振,確保音質不受影響,HS-453DX在外型、功能與抗噪音方面都十分適合用來做為家中的串流中樞。當然除了音樂之外,串流影片也是常見的用法,也能讓NAS在備份之餘有更多的應用。

可擴充的M.2快取、雙硬碟槽

儲存空間的部分主要是靠著2個支援快拆的3.5吋硬碟空間,當然你也可以換成速度更快的SSD或是2.5吋硬碟。另外HS-453DX還有預留2個M.2 2280插槽可以安裝SSD用於快取,系統記憶體則有2個插槽,出廠時可選擇要4GB還是8GB的版本。

此外,處理器搭配的是Intel Celeron J4105四核心處理器,另外還有雙HDMI輸出,充當HTPC也沒什麼大問題,也能支援4K影音串流播放還有即時轉檔。不論是要看電影,還是重溫運動攝影機的影片都很方便。

高速10GbE網路埠

QNAP這次在HS-453DX上還給了10GbE的網路埠,可以讓你用高速的有線網路傳輸資料,當然要跑到10GbE的速度在線材、裝置端都需要同步最佳化,才能跑到接近理論速度。但給了10GbE的網路埠,至少在網路傳輸上不用擔心頻寬吃緊的問題,也能減少傳遞大檔案的時間,或是給予多人環境下更有餘裕的頻寬條件。

外型、硬體兼具的特色NAS

整體來說,HS-453DX有著2018年Computex d&i設計獎及CES 2019 創新獎的加持,還有無風扇低噪音的特性,有別於傳統NAS給予的刻板印象,另外在10GbE網路、Intel Celeron J4105、HDMI 2.0雙輸出以及雙M.2預留插槽,則是代表有足夠的硬體規格應付現在NAS要面對的影音新環境。如果近期想要找個有別於一般的家用NAS,那麼安靜又有特色的HS-453DX不妨可以考慮看看。
