Despite not being officially announced by Sandisk, the WD Black SN8100 is availa
ble for pre-order at Amazon (Germany) at the equivalent of $225 for the 1TB vari
ant, via momomo_us. With listed reads of 14.9 GB/s, this should be the fastest
consumer PCIe 5.0 SSD, at least if we're talking about on-paper specifications.
Beyond what the Amazon listing offers, technical details, including the specifi
c controller and NAND flash type, remain unknown.
尽管 Sandisk 尚未正式发布，透过 momomo_us 在德国亚马逊（Amazon Germany）已开放预
购 1TB 款，等值价格为 225 美元。标示读取速度达 14.9 GB/s，若仅论纸面规格，将成
为最快的消费级 PCIe 5.0 SSD。除了亚马逊页面显示资讯外，其具体采用哪款控制器及 N
AND 快闪存储器种类尚未可知。
Western Digital's flash-memory business has been handed over to the now-independ
ent Sandisk, following its spin-off from the company. In theory, this should ext
end to Western Digital's acclaimed WD Black lineup, though end-users are unlikel
y to experience any significant changes. The bottom line is that Sandisk will pr
obably be responsible for bringing the SN8100 to market, handling everything fro
m launch to customer support, but it will be marketed with Western Digital's wel
l-known WD label.
Western Digital 的快闪存储器事业在分拆后已移交给独立运作的 Sandisk。理论上，这也
包含了知名的 WD Black 系列，不过终端用户应不会察觉明显差异。重点是：SN8100 后续
上市及客户支援等环节，极有可能由 Sandisk 负责，但依旧沿用 Western Digital 的 WD
商标进行行销。
The SN8100 is the first PCIe 5.0 SSD under the WD Black product line, and is li
sted with impressive read speeds of 14.9 GB/s, beating the best from Samsung, K
ingston, and Crucial, at least if we're going by first-party tests. The SN8100 i
s positioned as a successor to the WD Black SN850X, which was among the fastest
PCIe 4.0 SSDs back in its day.
SN8100 是 WD Black 系列首款采用 PCIe 5.0 规格的 SSD，官方标示读取速度达 14.9 G
B/s，若依据厂商自家测试，已超越 Samsung、Kingston 与 Crucial 的顶尖产品。此款定
位为 WD Black SN850X 的接班人，当年后者曾是最快的 PCIe 4.0 SSD 之一。
The listing's claim of an average operating power of 7W or less strongly suggest
s the SN8100 employs Silicon Motion's power-efficient SM2508 controller. That be
ing 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'l
l know for sure when Sandisk provides a complete technical datasheet. The NAND I
Cs employ a TLC (Triple Level Cell) design with CBA technology, likely sourced f
rom 8th generation (218-layer) NAND jointly developed by Sandisk and Kioxia.
亚马逊页面标示平均功耗不超过 7W，极可能代表 SN8100 采用了 Silicon Motion 的高效
能 SM2508 控制器。不过，Western Digital 在 FMS 2024 曾展出过一款读取达 15 GB/s
的原型机，使用自家控制器，功耗水准也相近。待 Sandisk 公布完整技术资料表后，就能
得到最终答案。 NAND 芯片采用 TLC（三层单元）设计，并结合 CBA 技术，极有可能出自
Sandisk 与 Kioxia 共同开发的第八代 218 层 NAND。
The WD Black SN8100 offers sequential reads and writes of up to 14.9 GB/s and 1
4.0 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 lo
ses to the 9100 Pro in random writes, thanks to Samsung's proprietary Presto con
troller. The SN8100 is said to launch in 1TB to 4TB capacities, but as of writin
g, only the 1TB model is listed for pre-order.
WD Black SN8100 的连续读写速度分别最高可达 14.9 GB/s 与 14.0 GB/s，随机读写性
能标示为 2,300K IOPS。根据外泄数据，其在连续测试中击败所有同级 SSD，但因 Samsung
独家 Presto 控制器，随机写入速度略输给 9100 Pro。据称将推出 1TB 至 4TB 容量，不
过截至目前仅 1TB 款可预购。
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 deli
veries scheduled to begin on May 30. Hopefully, we will see an official announce
ment by then.
价格方面，1TB 款标示 225 美元（约 199.99 欧元），相当于每 GB 约 22.5 美分。相比
之下，PCIe 4.0 SSD 目前平均仅需 6–7 美分／GB，促销期间更低。考量到这点，德国地
区用户可在亚马逊预购，预计 5 月 30 日开始出货。希望届时能看到官方正式发布。
