A microSD card with a capacity of up to 1.5 TB is suitable for expanding the memory of the Samsung Galaxy Tab S10 Ultra (WLAN only), as the tablet supports microSD cards up to this size. High speed microSDXC cards, ideally Class 10 or higher, are particularly recommended to ensure optimal performance, especially for 4K UHD video recording. A 1 TB microSD card that fulfils these criteria is therefore well suited to expanding the tablet's memory.
