Mercury Elite Pro Quad USB3.1 Gen2,支援 USB-C 10Gbps。這些或許在其他品牌都還能找到競品,但 OWC 這款 ThunderBay 4 mini,應該是真的沒對手了,2.5" SATA 4Bay,傳輸介面 Thunderbolt。基本上就是 ThunderBay 4 的迷你縮小款,但因為這個迷你,將這款 ThunderBay 4 mini 切入到一個沒有競爭者的 2.5" 產品定位。再加上 OWC 自家 SoftRAID 的 RAID5 功能,打造強硬的軟硬體壁壘,讓其他品牌難以撼動打入 Mac User 市場,實在高明。 這次選擇的是外接盒不帶容量的款式,所以盒裝正面貼有 0GB Enclosure 的貼紙。其中又分為兩個版本,純外接盒是 $8,250。而這次選擇的是具有 SoftRAID 功能的版本,價格是 $11,550,價差約 $3,300。OWC ThunderBay 4 mini 盒裝重量約 2,086g。 盒裝背面有產品功能簡介,其中標示採用靜音風扇,從產品片上便可以看到其風扇採用 Noctua 的風扇,具體型號後面介紹。保固標示具體三年保固,不過這是給內建具備容量的版本才有三年保固。像這樣單買 ThunderBay 4 mini 外接盒,保固只有一年。 打開盒裝,可以看到 SoftRAID 說明、產品說明以及一張 Acronis Cyber Protect Home Office 一年序號。 雖然本來就是看中 ThunderBay 4 mini 的極小體積,也預期體積不會太大。不過實際到手,從箱子中拿出 ThunderBay 4 mini 時,還是被其小巧的體積震撼到。相較 3.5" 的陣列外接盒,這個小體積真的是太棒了!重量也輕非常多。 3.5" 4 Bay 的外接盒機種又大又重,放在桌上勉強還可以,但絕對無法放到 iMac 後方與牆壁之間的空間。而 OWC ThunderBay 4 mini 橫放在 iMac 後,空間完全足夠,其尺寸為:寬 96mm x 高 117mm x 深 194mm。 機身後方,上 2/3 的區域是風扇出風。下方則是 I/O 區域,左側一個 Kensington 防盜鎖孔、兩個 Thunderbolt 以及一個電源輸入。電源規格為 12V ⎓ 6A 約 72W 規格。 所有主要硬體陳列。由左至右依序為 ThunderBay 4 mini 本體、電源供應器、電源轉接線、托盤螺絲、鑰匙兩把以及 USB-C to USB-C 線一條。 打開前面板一定需要鑰匙,所以鑰匙要格外小心收好,否則防諜未成,先雷到自己。有鑰匙在安全性上肯定是加分,但希望有無鑰匙的版本或下一代可以優先考慮這個方式,目前就看看之後可否自己改裝。現階段是常態性的把鑰匙插著,避免不見。 OWC 提供兩把鑰匙也算有個備份,而我自己的習慣,容易收一收,過一年後就忘記了。所以還是讓兩把鑰匙生人與共,比翼雙飛。最壞的打算也問好了,如果兩支鑰匙真的一起蛻變成蝴蝶飛走了,向 OWC 再購買一套兩把的價格是 $330,還算是負擔得起。 這是之前評測六顆 SATA SSD 的景象,土炮用了一個機殼的 3.5" 硬碟架當固定座,以方便 SATA 傳輸線和 SATA 電源線整理。其實光六顆 SATA SSD 就需要用到 12 條線(6 條 SATA 電源線+6 條 SATA 傳輸線),在裸測上其實非常繁雜,用上硬碟架後改善不少,雖然線多,但至少整齊。圖中也可以看到,採用正反交錯擺放的方式。這是因為有些 SATA 傳輸線頭是 L 型,透過交叉擺放拉出更大的間距才不會卡到。以及 SATA 電源線的線身即便很軟,但距離過近對接頭來說還是有一定擠壓的力量。藉由正反交錯方式,拉開距離避免線頭與 SSD 接頭承受太大的力量。而且這樣就可以簡單分為兩組(每組三顆)來管理,妙哉,妙哉。 不過這也體現出硬碟架的必要性,可以方便管理磁碟陣列。而且市場上大多陣列產品都針對 3.5" 硬碟來設計,好處雖是可以向下相容 2.5"。但對於明確只需要 2.5" 陣列的使用者來說,無疑就浪費了許多空間。偏偏專門給 2.5" 陣列的外接設備非常少,不論是 USB 協議和 Thunderbolt 協議,目前只有找到 OWC ThunderBay 4 mini 符合我的需求,若大家有看到類似的產品也可以回應分享。總之目前所看到的市場和競品,OWC ThunderBay 4 mini 鎖定的 2.5" 消費者的需求真的非常精準。 SATA SSD 部分選擇的是 Crucial MX500 4TB,不僅容量大、速度穩定、價格便宜、散熱好,實際運作時的溫度低,對於散熱上的壓力會比較小。不管是長時間待命使用或是追求靜音、改裝降低外接盒風扇速度,在溫度範圍內會有更多操作空間。這也是我這套組合選擇 SATA 而非 M.2 的原因,在 SATA SSD 本身發熱不高的情況下,MX500 在外接盒中有本錢挑戰完全被動的散熱改裝。而 OWC ThunderBay 4 mini 的托盤支架也滿特別的,採用中框固定的方式,且中框為鋁材質,重量意外地輕巧。 有點美中不足的是,Thunderbay 4 mini 採用外置電源供應器的方式,對於理線上會有一點煩瑣。不過外置電源的好處也明顯,假如哪天電源供應器壞掉,其實只要找個 12V ⎓ 6A,接頭通用的電源供應器就可以搞定,而不用去擔心機身內特規的電源模組。 後 I/O 部分前面有介紹,這邊想著重在 Thunderbolt 的部分。皆有螺絲孔支援 OWC ClingOn USB-C,可以更好地保護接頭。其實也有考慮過 USB-C 10Gbps 的機種,但是市面上沒有找到針對 2.5" 的款式。而且 OWC 價格其實也不貴,市面上許多 USB-C 3.5" 的外接陣列也要 $5,000~$6,000。而 Thunderbolt 產品經常是 USB-C 10Gbps 兩倍,但是 OWC ThunderBay 4 mini 單機是 $8,250,並沒有因為本身特殊規格而拉高太多價格。而這次選擇的是搭配 SoftRAID 的版本,價格是 $11,550。而 SoftRAID 的價值對 Windows 使用者來說不明顯,但對 macOS 的使用者來說非常方便,後面會再提到。而速度方面採用 Thunderbolt 雖然有點浪費,但其具有 downstream 設計,因此即便下行裝置再接個 USB-C 10Gbps SSD 的 1,000MB/s,加上自身四顆 SATA SSD 陣列約 1,500,兩者在 Thunderbolt 32Gbps 的資料頻寬是不會影響速度發揮。若使用 USB-C 10Gbps 就會一起塞車了,所以這也是 ThunderBay 4 mini 的可以更加彈性部署的優勢之一。 接著就是分解剖析其設計,上排由左至右是四個 2.5" Bay 的托盤、SATA 擴充板、Thunderbolt 板和內側前面板。下排則是後方風扇外殼、鋁擠型機身主體和 2.5" 硬碟籠。 Thunderbolt 板子的部分,中心是 Thunderbolt 晶片,為 Intel JHL6540,以 PCIe x4 連接到另一張轉接板。比較特別的是,以 Thunderbolt 產品來說,他不支援 PD 充電,Thunderbolt 僅作為傳輸使用。其實也非常合理,與其因為加上 PD 充電而讓電源供應器更大、板子更複雜、溫度更高以及整體成本售價提高,還不如捨棄 PD 充電的功能,專職做好儲存和傳輸即可。畢竟對於桌機使用情境來說,本身就沒有額外供電的需求,即便對筆電來說,供電也不是非常必要,因此我認為 OWC 這樣選擇是比較好的。板子上看來原本也預留了其他 I/O,可能是標準大小的 DisplayPort 接頭。電源則是從轉接板供應,從 Thunderbolt 板子右上角白色接頭輸入。 而滿有趣的是,常見 Thunderbolt 板子上同時會有電源輸入,讓電源控制與 Thunderbolt 晶片較近。ThunderBay 4 mini 是設計在轉接板上,電源輸入是右下角黑色接頭的排插。右上角則是輸出到 Thunderbolt 的電源,以及風扇控制接頭。 轉接板的另一面則可以看到四個 SATA 連接,下方兩顆 ASMedia ASM1062,一顆控制兩個 SATA。ASM1062 為 PCIe Gen2 x2 轉 SATA 的方案,而受限於 PCIe Gen2 x2 頻寬只有 1GB/s,加上其編碼方式為效率較低的 8b/10b,理論上實際傳輸速度只有 800MB/s。兩組 ASM1062 可以達到 1,600MB/s,這也是官方標示速度為 1,556MB/s 的原因。不過即便用上頻寬更大的方案,四顆 SATA 的極限大概也是 2,000MB/s 左右,並沒有完全吃滿 Thunderbolt 速度。但分析認為速度往上除了成本考量,可能也有 Thunderbolt 經過轉接後速度無法真實發揮,以及 Thunderbolt 優先提供頻寬給影響輸出而影響資料有效使用頻寬的顧慮。例如大多 M.2 PCIe Gen3 x4 SSD 實際速度也只有 2,000~2,800MB/s。而且還要考慮到 Thunderbolt 會優先將頻寬分給影像輸出,也就是在整個 Thunderbolt 匯流排上只要有影像輸出在運行,其他資料傳輸的頻寬就會被迫讓行而自降速度。因此若用上兩顆 ASMedia ASM1164(PCIe Gen3 x2 轉四顆 SATA),配上八顆 SATA SSD 在理論上吃滿其頻寬,實際表現速度可能也不會這麼理想,很可能僅比現在速度快一些而已。加上 OWC 算是非常早就推出這台 ThunderBay 4 mini,因此我覺得這樣的設計其實相當合理。此外大方向來說,接下來市場趨勢會持續朝 M.2 發展,應該不太有機會看到 OWC 或其他廠商推出 8 Bay 專門給 2.5" 的外接盒機種。 風扇為排風設計,使用 Noctua NF-A6x25 FLX,靜音效果不錯,散熱效果和壽命上也比較放心。加上這次搭配的 Micron Crucial MX500 4TB 本身發熱不大、金屬外殼散熱加。實際使用 SSD 溫度和 ThunderBay 4 mini 外殼就是溫溫的而已,散熱方面不太擔心。噪音方面比 iMac 27 5K 的風扇低轉速時時稍微大聲一點,但基本上已經算很安靜了。 電源經由背板輸入後,並非用連接線,而是經由板子連接到轉接板。滿特別的,比較少看到消費級產品有這樣的設計。對於拆裝上會稍微困難一點,但正常也不會有人拆開來看啦。 考量到 Apple Silicon 的 Mac 機種,搭配 Thunderbolt 外接裝置時,寫入速度會較慢的顧慮,這次還是優先使用 Intel CPU 的 Mac 來當測試平台。使用 Apple iMac 27 5K 2019。 在 macOS 中的 Disk Utility 可以將磁碟陣列設為 RAID0 或 RAID1,但無法設定成 RAID5。而 SoftRAID 的強項在於,在 macOS 上能做到 RAID5,不過先以最快速的 RAID0 來測試。在 SoftRAID 中,將四顆磁碟同時選曲,並執行「新增磁區」。 SoftRAID 會挑出新的視窗,開始引導建立 Volume。 根據預設 Block Size 為 16KB,也可以自行調整單元區塊大小。設定上比較方便,是比 macOS 內建的 Disk Utility 更方便之處。這個調整的差異,在於使用者可以針對不同檔案儲存類型來調整,藉此來優化讀寫效率。 現在我們有兩套 SoftRAID 序號可以運用,目前安裝在不同電腦。若在 A 電腦對磁碟陣列設定好 RAID 組態,將磁碟陣列搬到具備 SoftRAID 的 B 電腦上,也是可以正常運作。 以 Blackmagic Disk Speed Test 測試,檔案大小 5GB。寫入速度約 1,121MB/s,讀取速度約 1,286MB/s。 以 AJA System Test 測試,檔案大小 4GB。寫入速度 1,143MB/s,讀取速度1,339MB/s。 將檔案大小調整為 64GB。寫入速度 1,202MB/s,讀取速度 1,326MB/s。 另外這次使用 AmorphousDiskMark,設定測試為五次 4GiB,循序讀取速度接近 1,500MB/s,讀取也有 1,384MB/s。其中在 QD1 測試條件下,較符合實際使用場景,循序讀取速度約 1,028MB/s,循序寫入約 937MB/s。 除了在 Intel CPU 的 Mac 上測試,也在 Apple Silicon 平台測試。使用 MacBook Air M2。Apple Silicon 的 Mac 在使用 Thunderbolt 外接裝置時,通常讀取速度是正常,但是寫入速度會降低到一半,約 1,000~1,500MB/s。而 ThunderBay 4 mini 極限 1,500MB/s 的速度,其實也差不多。不過實際能測到多少,還是實操看看。 有趣的是,在 MacBook Air M2 上運行,讀寫成績還略好一點。以 Blackmagic Disk Speed Test 測試,檔案大小 5GB。寫入速度約 1,435MB/s,讀取速度約 1,298MB/s。 不過在 AJA System Test 中,Apple Silicon 的機種速度就稍慢一點。檔案大小 4GB。寫入速度 1,032MB/s,讀取速度1,249MB/s。 OWC ThunderBay 4 mini 本身主打的定位太精準,在 2.5" 市場完全沒對手。且採用 Thunderbolt 介面,讓速度可以比 USB-C 10Gbps 更高一些。雖然不見得能完全發揮四顆 SATA SSD 的速度,但是更高的總頻寬,適合同時執行更多儲存設備的傳輸。最重要的還是回到體積優勢,一般 3.5" 4 bay 外接盒都滿大的,體積大概是 ThunderBay 4 mini 兩倍,放在桌上不太方便。而 ThunderBay 4 mini 的小巧程度,甚至放在 iMac 背後都放得下。目前藉由四顆 Crucial MX500 4TB 組成大容量 16TB RAID0,完整使用其容量,並發揮 1,000~1,500MB/s 的速度,預計未來作為工作主力機的外接儲存。也會朝改裝 Fanless 或降低轉速聲音的方向嘗試,以期能做到長時間待命的外接儲存設備。
