SSD。Thunderbolt SSD 本身就是我經常使用的品類,因此就點進官網進一步看介紹,發現其是比較少見的 Thunderbolt、USB 雙模 SSD。也就是説,雖然都是 USB-C,但他既支援 Thunderbolt 協議,也能支援 USB 協議。USB-C 10Gbps 的外接 SSD 是目前市場銷量最多、能見度最高的品類。而 Thunderbolt SSD 雖然速度快,價格高昂且支援設備有限,個人手上大概有十顆左右。而像 PRO-G40 SSD 這樣同時支援兩種協議的外接 SSD,成本和價格自然更高。扣除掉簽了 NDA、在展場看過和沒有公開販售的,PRO-G40 是我在消費性市場、手上拿到的第二款雙模的外接 SSD。 <figure style="clear:both;"> <div role="button" tabindex="0"> <div

背面完全是橡膠材質包覆,手掌握持感不錯。因為表面摩擦力較大,拿在手上也格外順手。相較大多橡膠材質也比較不一樣,並非全黑,而是帶有一點灰色。且具有一定厚度,用力捏起來可以感受到它的彈性。表面非常光滑,雖然如同大多此材料,沾到小灰塵就會特別明顯,但是因為光滑,所以拍一拍、抹一抹就掉了。若真的不行,既然都防水了,就直接用水沖一沖吧。 <figure style="clear:both;"> <div

2,143MB/s,混合效能 3,179MB/s。循序讀取和寫入都有極優的發揮,更意外的是通常混合讀寫都會稍低,沒想到 PRO-G40 的混合讀寫還一路突破到接近 3,200MB/s。要知道,雖然在最佳效能模式是眾所週知的快樂錶,但是經驗上來說 Thunderbolt SSD 實測能發揮出理論值 90~60% 效能都算正常。而 SanDisk Professional PRO-G40 SSD 幾乎是貼著理論值在跑,這其中應該是有特別花心思調教過,才能有這樣的成績。這也是大多 DIY 玩家,即便買了頂規 SSD 和 Thunderbolt SSD 外接盒自己組裝,實測速度無法跑到那麼極限的原因。 <figure style="clear:both;"> <div role="button" tabindex="0"> <div

USB 協議的 External SSD。而 USB 的電腦,可以連接 USB 協議的 External SSD,卻無法支援 Thunderbolt External SSD。這就造成一個現象,價格較貴的 Thunderbolt SSD,其支援性、泛用性反而較差。如果不是像我們大多電腦都具備 Thunderbolt 介面,也刻意投資建置 TBT 生態,那麼跳級選擇 Thunderbolt 可能會讓你的工作流,或與別人協作上造成困擾。而像 PRO-G40 SSD 天生支援兩個協議,因此在傳輸上會方便很多。例如現在內部工作流,若不想透過內網傳輸,就會優先使用像 PRO-G40 這樣的雙模 SSD 來傳輸資料,既可以享受 USB 的泛用性,連接到支援 Thunderbolt 的電腦時,也能發揮 2,000~3,000MB/s 的高速。 <figure

$17,980。定價確實不算低,特別是現在 SSD 市場價格跳水劇烈。不過其在價值方面也充分體現其定價的能力,怎樣盡力把一款 SSD 做到好。Thunderbolt External SSD 本來就比 USB3.2 Gen2 10Gbps External SSD 貴一~四倍,而 PRO-G40 是兩者結合,價格比 Thunderbolt External SSD 高也是市場行情。且 SanDisk Professional 品牌,本身就是針對專業用戶的專業生產力需求,而不是普羅大眾的日常家用情境,在耐用性上的確也看到 PRO-G40 有更多著墨和保證,提供了五年保固。 <figure style="clear:both;"> <div role="button" tabindex="0"> <div
