The advertised WD Black 4TB SN850X SSD deal was a historical offer, not a confirmed current price. An ExtremeTech article published November 27, 2024, reported the drive at $249.99 and described that as 64% off. The available information does not establish today’s price or stock.

What the 2024 Black Friday offer included

The deal covered the WD Black 4TB SN850X, an internal NVMe SSD. ExtremeTech’s November 27, 2024 article reported a price of $249.99 and a 64% discount. Those figures describe the offer at that time; they do not confirm that the price or discount is available now. Read the original ExtremeTech deal article.

What kind of drive is the SN850X?

The SN850X is a high-capacity internal NVMe SSD. The deal article presented it as an option for gamers, streamers, and creators, and reported sequential speeds of up to 7,300 MB/s. That speed is the article’s claim; it was not independently confirmed by the official WD result available here. A maximum sequential-speed figure also does not, on its own, predict performance in every real-world workload.
