Model comparison
Ninja DualZone 8 qt or 10 qt?
Ninja basket-size comparison
The DZ801 and DZ901SD are both two-basket Ninja DualZone models, but their exact U.S. pages do not provide the same level of detail. Compare the listed total capacity, the baskets' documented split, Smart Finish, counter dimensions and the manual information you need before treating them as interchangeable.
Start with what the pages actually establish
The DZ801 is listed as 8 qt total, explicitly split into two 4-qt baskets. Its exact page names Smart Finish and Match Cook: the first coordinates different cooking settings to finish together, while the second copies settings across zones. That gives a specific use case for a two-food meal and another for sharing a similar batch between drawers.
The DZ901SD is listed as 10 qt total with two independent baskets and Smart Finish. Its exact Stone & Gold page does not give an individual basket capacity and does not name Match Cook. It may be tempting to carry the gray DZ901's two 5-qt specification to the SD suffix, but a nearby finish listing is not a substitute for the exact variant's page. If you need to know whether a large cut fits one basket or require same-setting copy controls, verify those details before deciding.
What changes in a normal meal?
Both exact pages describe two independent baskets, so both can separate foods and let each zone use its own settings. Smart Finish on both pages is the clearest shared meal-planning feature: when two foods need different times or temperatures but you want them ready together, it coordinates the end time. The page-level feature set on the DZ801 is better documented for matching settings across baskets. The DZ901SD's exact page does not answer that question, so treat its Match Cook behavior as unknown rather than guaranteed.
The 8-qt DZ801 is the more transparent choice if knowing the drawer split matters: the manufacturer says two 4-qt baskets. The 10-qt DZ901SD has a larger listed combined figure, but that does not prove a single 10-qt cavity or a specific piece of food will fit. Even where an overall capacity is adequate, each ingredient still has to fit the actual basket opening. Neither model has an exact U.S. owner guide established in this review set, so full temperature/time ranges, basket dishwasher care and electrical supply remain questions to settle before purchase.
Side-by-side shape and counter fit
Both products use a side-by-side layout rather than vertically stacked drawers. SharkNinja lists the DZ801 at 14.96 inches long × 14.57 inches wide × 12.2 inches high and 16.76 pounds. It lists the DZ901SD at 16.93 inches long × 14.57 inches wide × 12.6 inches high and 19.4 pounds. These are manufacturer dimensions, not independently measured fit tests. On those figures, the 10-qt model is longer and taller while the listed width is the same. Confirm the maker's measurement orientation against your counter and leave room for drawers to slide fully out and for ventilation.
If you have a high shelf or want two baskets in a narrower side-to-side presentation, the Ninja DoubleStack SL201 offers two 4-qt baskets in a vertical arrangement. That trades the side-by-side footprint for height and a different drawer orientation. If your priority is one wide cooking area that can split into two zones, compare a removable-divider design such as the Ninja FlexBasket rather than equating any two baskets with a divided single drawer.
Mode names and care deserve a manual check
The DZ801 U.S. page contains two different six-function lists: its Details section names Broil, while its Highlights section names Max Crisp; the exact model image also shows Air Broil and Max Crisp labels. The DZ901SD Highlights list names Max Crisp, while its exact hero image shows an Air Broil label. Without each U.S. owner's guide, do not choose either by an essential Broil/Air Broil/Max Crisp requirement. The DZ801 page specifically confirms dishwasher-safe crisper plates but not dishwasher-safe baskets. The DZ901SD exact page does not state basket or plate care. Neither exact page establishes coating chemistry or a PFAS-free claim.
A practical decision rule
Start with the DZ801 if 8 qt total, two documented 4-qt drawers, digital buttons and the listed Match Cook/Smart Finish pair match your routine. (The exact program labels still need clarification.) Consider the DZ901SD if the 10-qt combined figure and Stone & Gold finish matter more, you do not require a documented 5-qt-per-side split, and Smart Finish covers your meal timing need. If a cleanable basket, exact mains rating, particular mode, probe, or minimum temperature is essential, do not guess: choose a documented alternative or wait for the exact code's U.S. guide.
