[情報] WD SN8100 出現在德國亞馬遜

Despite not being officially announced by Sandisk, the WD Black SN8100 is available for pre-order at Amazon (Germany) at the equivalent of $225 for the 1TB variant, via momomo_us. With listed reads of 14.9 GB/s, this should be the fastestconsumer PCIe 5.0 SSD, at least if we're talking about on-paper specifications. Beyond what the Amazon listing offers, technical details, including the specific controller and NAND flash type, remain unknown.

儘管 Sandisk 尚未正式發布，透過 momomo_us 在德國亞馬遜（Amazon Germany）已開放預購 1TB 款，等值價格為 225 美元。標示讀取速度達 14.9 GB/s，若僅論紙面規格，將成為最快的消費級 PCIe 5.0 SSD。除了亞馬遜頁面顯示資訊外，其具體採用哪款控制器及 NAND 快閃記憶體種類尚未可知。

Western Digital's flash-memory business has been handed over to the now-independent Sandisk, following its spin-off from the company. In theory, this should extend to Western Digital's acclaimed WD Black lineup, though end-users are unlikely to experience any significant changes. The bottom line is that Sandisk will probably be responsible for bringing the SN8100 to market, handling everything from launch to customer support, but it will be marketed with Western Digital's well-known WD label.

Western Digital 的快閃記憶體事業在分拆後已移交給獨立運作的 Sandisk。理論上，這也包含了知名的 WD Black 系列，不過終端用戶應不會察覺明顯差異。重點是：SN8100 後續上市及客戶支援等環節，極有可能由 Sandisk 負責，但依舊沿用 Western Digital 的 WD商標進行行銷。

The SN8100 is the first PCIe 5.0 SSD under the WD Black product line, and is listed with impressive read speeds of 14.9 GB/s, beating the best from Samsung, Kingston, and Crucial, at least if we're going by first-party tests. The SN8100 is positioned as a successor to the WD Black SN850X, which was among the fastestPCIe 4.0 SSDs back in its day.

SN8100 是 WD Black 系列首款採用 PCIe 5.0 規格的 SSD，官方標示讀取速度達 14.9 GB/s，若依據廠商自家測試，已超越 Samsung、Kingston 與 Crucial 的頂尖產品。此款定位為 WD Black SN850X 的接班人，當年後者曾是最快的 PCIe 4.0 SSD 之一。

The listing's claim of an average operating power of 7W or less strongly suggests the SN8100 employs Silicon Motion's power-efficient SM2508 controller. That being said, Western Digital did show off a prototype 15 GB/s SSD last year at FMS 2024, which leveraged an in-house controller, with comparable power draw. We'll know for sure when Sandisk provides a complete technical datasheet. The NAND ICs employ a TLC (Triple Level Cell) design with CBA technology, likely sourced from 8th generation (218-layer) NAND jointly developed by Sandisk and Kioxia.

亞馬遜頁面標示平均功耗不超過 7W，極可能代表 SN8100 採用了 Silicon Motion 的高效能 SM2508 控制器。不過，Western Digital 在 FMS 2024 曾展出過一款讀取達 15 GB/s 的原型機，使用自家控制器，功耗水準也相近。待 Sandisk 公布完整技術資料表後，就能得到最終答案。 NAND 晶片採用 TLC（三層單元）設計，並結合 CBA 技術，極有可能出自Sandisk 與 Kioxia 共同開發的第八代 218 層 NAND。

The WD Black SN8100 offers sequential reads and writes of up to 14.9 GB/s and 14.0 GB/s, while its random read and write performance is listed at 2,300K IOPS. According to the leaked numbers, it beats every SSD in sequential tests, but loses to the 9100 Pro in random writes, thanks to Samsung's proprietary Presto controller. The SN8100 is said to launch in 1TB to 4TB capacities, but as of writing, only the 1TB model is listed for pre-order.

WD Black SN8100 的連續讀寫速度分別最高可達 14.9 GB/s 與 14.0 GB/s，隨機讀寫性能標示為 2,300K IOPS。根據外洩數據，其在連續測試中擊敗所有同級 SSD，但因 Samsung 獨家 Presto 控制器，隨機寫入速度略輸給 9100 Pro。據稱將推出 1TB 至 4TB 容量，不過截至目前僅 1TB 款可預購。

In terms of pricing, the 1TB variant is listed at $225 (€199.99), or about 22.5 cents per Gigabyte. This is significantly more expensive than PCIe 4.0 options, which currently average around 6–7 cents per gigabyte; even less during sales. Bearing that in mind, German users can pre-order this SSD at Amazon, with deliveries scheduled to begin on May 30. Hopefully, we will see an official announcement by then.

價格方面，1TB 款標示 225 美元（約 199.99 歐元），相當於每 GB 約 22.5 美分。相比之下，PCIe 4.0 SSD 目前平均僅需 6–7 美分／GB，促銷期間更低。考量到這點，德國地區用戶可在亞馬遜預購，預計 5 月 30 日開始出貨。希望屆時能看到官方正式發布。

ChatGPT 怎麼翻得爛爛的，
我明明有開思考模式了......

以前 Gen5 SSD 總是會帶給人燒燙燙的印象，
所以板上一直不是很推薦購買，
最近搭載台積電 7nm 等級製程的控制器好像準備推出產品了，
不知道科技能不能征服 Gen5 SSD 的熱量，
讓 Gen5 SSD 進入主流市場。
