Running out of storage is absolutely the most frustrating experience, because it forces you into an endless hell of deleting games, downloading new ones, craving old favorites, and redownloading them all over again.
Whether you are a dedicated hardcore gamer or a weekend casual player, grabbing the right memory card does more than just expand your Nintendo Switch capacity—it instantly upgrades your entire gaming experience to first-class.
In this guide, I will walk you through three crucial points: why your Switch desperately needs a memory card, what types are out there, and how to pick a high-performance card.
By the end of this read, you will safely leave those confusing specs behind and effortlessly take your gaming storage to the very next level.
1. Why You Should Upgrade to an SD7.1 Memory Card
Beyond capacity, speed is an absolutely crucial factor. Traditional UHS-I microSD cards worked perfectly on previous-generation consoles, but as game data sizes continue to explode, the demand for faster read speeds is skyrocketing.
Today, modern games easily consume tens of gigabytes, and a single AAA blockbuster can demand well over 50GB of space. Just look at massively popular titles like Hitman or Cyberpunk 2077.
| Feature | UHS-I microSD | microSD Express 7.1 |
|---|---|---|
| Interface | SD Bus | PCIe Gen3 x1 + NVMe |
| Theoretical Max Speed | ~104 MB/s | ~985 MB/s |
| Typical Real-world Speed | 80–100 MB/s | 600–880 MB/s |
| Random Read/Write (IOPS) | ~4K / 2K | ~65K / 52K |
| Primary Use Case | Phones, Cameras, Drones | Next-gen Consoles, VR, AI |
| Technology Generation | Legacy Architecture | SSD-like Architecture |
| Backward Compatibility | — | Backwards compatible (reverts to UHS-I speeds) |
MicroSD Express 7.1 leverages PCIe + NVMe technology to reach theoretical speeds of up to 985MB/s, nearly 10 times faster than traditional UHS-I microSD cards.
Because of this performance leap, many gamers are opting for high-capacity SD7.1 cards. With 256GB and 512GB options, you have ample space to keep all your games, patches, and DLCs in one place. It essentially turns your console into a dedicated portable library—everything is ready to launch at a moment’s notice, allowing you to install AAA titles and future updates with ease.
The defining difference of microSD Express 7.1 is its PCIe transmission architecture. The ultra-fast read/write performance of PCIe Gen3x1 significantly boosts data throughput. For gamers, this translates to:
- Faster game loading times
- Smoother data streaming
- Increased stability during heavy gameplay
Think of it this way: if UHS-I is a local road, Express 7.1 is an express highway—data passes through without a bottleneck, and your overall gaming experience becomes significantly smoother. Consequently, the SD7.1 memory card is the superior choice for next-generation gaming consoles.
2. Memory Card Types Compatible with Nintendo Switch
Currently, the Nintendo Switch series of consoles supports the following types of microSD memory cards:
| Memory Card Type | Capacity Range | Key Features | Switch Compatibility | Switch 2 Compatibility |
|---|---|---|---|---|
| microSDHC | Up to 32GB | Basic storage capacity | ✅ Supported | ⚠️ Compatible but not recommended |
| microSDXC | 64GB – 2TB | High capacity, standard choice | ✅ Supported | ⚠️ Limited functionality |
| microSD Express 7.1 | Common in 256GB+ | PCIe high-speed, next-gen performance | ❌ Not supported | ✅ Best choice |
For modern games that easily consume tens of gigabytes, microSDXC or microSD Express cards are much more practical choices.
If you are looking to balance high capacity with top-tier performance, the AGI TF338 microSD Express 7.1 memory card is undoubtedly the ultimate choice for upgrading your storage.
