Q&A-4 Supports simultaneous read/write across all 8 card slots, including cross-group and same-group card operations. Q&A-5 The 8 interfaces are grouped into 4 sets (adjacent SD/TF cards form a group). Each pair of slots within a group shares 104MB/s bandwidth, resulting in a total bandwidth of 416MB/s. Q&A-6 The DC 5V power interface is not required for light use. It may be needed when using storage cards exceeding 1TB capacity or connecting to a USB 2.0 port (this product does not include a USB 5V power adapter). Q&A-7 The included Type-C adapter supports connection to devices running Android, iOS, macOS, HarmonyOS, and other systems (including mobile OTG devices). Note-1 Data transfer rates depend on the memory card's performance and your computer's USB port speed. Note-2 If large file transfers fail, try formatting the memory card as follows: MS-DOS (FAT) for 32GB or smaller cards, exFAT for 64GB or larger cards. Note-3 The product's exterior is made of solid wood. Each piece may exhibit slight variations in grain pattern due to natural wood processing. Note-4 Handcrafted + precision-machined corners may contain wood shavings or minor imperfections, which are normal.replacement if significant issues arise!
