Pros & Cons
👍 Pros
- 120MB/s rated read speed exceeds the Switch's internal storage bandwidth, ensuring game load times from the card are not meaningfully slower than internal storage for typical titles.
- A1 performance rating guarantees minimum random I/O specs, preventing the frame-rate hitching and load stuttering that unrated cards can introduce during active gameplay.
- 256GB capacity accommodates the full digital Switch library most users accumulate — large first-party titles average 6–14GB, putting 15–30 major titles comfortably on a single card.
- Bundled multi-slot card reader with SD, Micro SD, M2, and MS support adds genuine utility for PC-side transfers without an additional accessory purchase.
- Waterproof, temperature-proof, shockproof, and X-ray-proof durability ratings provide meaningful protection for a card stored in portable hardware subject to travel conditions.
👎 Cons
- Real-world write speeds on the Ultra line typically fall well below the rated read figure — while sufficient for Switch downloads, users who also use this card for high-bitrate 4K video recording on other devices will find the write performance a limiting factor.
- UHS-I bus interface (not UHS-II) caps theoretical maximum throughput at 104MB/s on the bus itself, which sets the ceiling for future use cases on devices that support UHS-II speeds.
- The A1 rating, while suitable for Switch game loading, is the lower of SanDisk's two app performance tiers — demanding applications on Android devices or sustained high-IOPS workloads will perform better on an A2-rated card.
- The bundled card reader connects via USB-A, which may require a separate adapter on newer laptops that have transitioned exclusively to USB-C ports.
