Choosing the Right Memory Card for Switch 2

The Switch 2 uses a new storage standard that differs from the original Switch, requiring microSD Express cards instead of standard microSD cards. Understanding these requirements helps you pick the right storage expansion for your gaming needs.

Why Switch 2 Requires microSD Express Cards

The Switch 2 needs microSD Express cards because standard microSD cards don't offer fast enough transfer speeds for the console's games. Nintendo designed the Switch 2 to run more complex games, which means larger file sizes and more data moving between the storage and the console's internal memory.

Standard microSD cards, including UHS-I cards, can't keep up with these demands. The games need faster read and write speeds to load quickly and run smoothly. If you try to use a regular microSD card in your Switch 2, it won't work at all.

The internal storage on the Switch 2 is limited, so most players will need additional space. MicroSD Express technology provides the speed boost needed for next-generation gaming performance.

microSD Express vs Standard microSD: What's Different?

MicroSD Express cards use a different technology than standard microSD cards. While regular microSD cards rely on older UHS-I (Ultra High Speed) standards, SD Express uses PCIe and NVMe interfaces. This is the same technology found in modern computer SSDs.

The speed difference is significant. Standard microSD cards max out at around 104 MB/s, while microSD Express cards can reach speeds over 985 MB/s. This means games load faster and the console can access game data without delays.

MicroSD Express cards are also backward compatible in their physical design, but the Switch 2 requires the Express standard specifically. You can't substitute one for the other in this console.

Capacity and Compatibility Considerations

MicroSD Express cards for Switch 2 come in several storage sizes. The most common options are 128GB microSD Express, 256GB microSD Express, 512GB, and 1TB microSD Express cards.

Your capacity choice depends on how you buy games. Digital downloads require more storage than physical cartridges. A single Switch 2 game can take up 15-30GB or more.

Here's a rough guide for storage needs:

• 128GB: 4-8 digital games
• 256GB: 8-16 digital games
• 512GB: 16-32 digital games
• 1TB: 32-64 digital games

All microSD Express cards work with the Switch 2 regardless of brand, as long as they meet the Express standard. The console will recognize any properly formatted microSD Express card you insert.

Building a complete gaming setup means optimizing every component. While your Switch 2 needs fast storage, your PC needs quality RAM. Learn more by checking out, DDR4 RGB Silver X: Transform Your Gaming Experience to upgrade your entire gaming ecosystem.

Performance, Storage Sizes, and Real-World Usage

MicroSD Express cards deliver read speeds up to 985 MB/s, which rivals entry-level SATA SSDs in PCs. The Switch 2 needs this speed to handle larger game files and faster load times compared to the original console.

Read and Write Speed Expectations

MicroSD Express cards use the PCIe interface, similar to NVMe SSDs in gaming laptops and desktop PCs. You can expect sequential read speeds between 800-985 MB/s with these cards. Write speeds typically range from 700-850 MB/s.

These speeds are much faster than the UHS-I cards used in the original Switch, which maxed out at 100 MB/s. The performance gap mirrors the difference between older SATA SSDs and modern NVMe drives in gaming PCs.

The faster speeds mean less bottlenecking when the Switch 2 loads game assets. Some cards include DRAM cache to improve small file performance, though this feature is less common in microSD formats than in full-size SSDs.

Game Load Times and Transfer Performance

Your game load times improve significantly with microSD Express cards. Games that took 30-45 seconds to load on the original Switch can load in 10-15 seconds on the Switch 2 with proper storage.

Transferring games from internal storage to your card takes minutes instead of hours. A 15 GB game transfers in roughly 20-30 seconds with high-end microSD Express cards. This speed approaches what you'd see with NVMe SSDs in laptops, though PC components still offer better sustained performance.

Background downloads and game updates happen faster too. The improved write speeds let your console install patches while you play other games without major slowdowns.
