Wd Black Sn850x Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Samsung is the best-performing wd black sn850x brand in July 2026, moving 14,000 units across 4 ASINs for 48.3% of Top 10 volume. Sandisk follows with 5,000 units (17.2%), ahead of Kingston on 4,000 units (13.8%).

With 5 brands splitting the Top 10 and 79.3% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $162.00 to $319.49, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, 2 ASINs forced its way in: B0DN7CYYSD booked 2K units at $185.99, with ▲ 100.0% MoM change. On the growth side, B0DM1R7KHZ leads positive momentum with ▲ 1900.0% MoM growth on 1K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
