| Brand | Model | Capacity | Format | Notes | | :--- | :--- | :--- | :--- | :--- | | | M3 Portable | 1TB / 2TB | FAT32 | The gold standard. Zero spin-down issues. Works with WiiFlow & USB Loader GX equally. | | Western Digital | My Passport Ultra (Gen 1 only) | 500GB / 1TB | NTFS | Do not buy the Gen 2 (USB-C version). The Gen 1 uses a legacy ASM1153 bridge chip that the Wii loves. | | Toshiba | Canvio Basics | 500GB / 1TB | FAT32 | Surprisingly perfect. Low power draw works even on launch-day Wii consoles with weak capacitors. | | SanDisk | Cruzer Glide (Flash Drive) | 128GB / 256GB | FAT32 | Warning: Flash drives are generally not recommended, but this specific model has a unique controller that respects the Wii’s timing. Do not use for GameCube games (stuttering FMV). | | Seagate | Expansion Desktop (External Power) | 1TB / 2TB | FAT32 | Requires a wall outlet, but never fails. Best for 24/7 homebrew setups. |
