128GB microSDXC Game Turbo card

This 128GB microSDXC card carries the Game Turbo branding and delivers read speeds up to 100MB/s with write speeds up to 50MB/s. It meets A2, Class 10, U3, UHS-I and V30 ratings for sustained performance. The card is built for smartphones, tablets, action cameras, drones and handheld gaming devices such as the Nintendo Switch.

Upgrade from slower Class 10 or U1 cards

Moving to this U3 and V30 rated card is worthwhile when you record 4K video or run apps directly from the card. The A2 rating improves random read and write performance for faster app loading on phones and tablets. If your current card cannot sustain 30MB/s write speeds, this model removes that bottleneck.

Suits mobile gamers and 4K camera users

This card fits users who need reliable 4K capture and quick app launches on Android devices, action cameras or the Nintendo Switch. Buyers who require higher capacities beyond 128GB or faster sustained write speeds for professional video workflows should look at higher-specification cards.

Questions about this item

Does the 128GB microSDXC card fit a full-size SD slot without an adapter?

No, the card is microSDXC form factor and requires a microSD-to-SD adapter to fit a full-size SD slot.

What is the correct way to insert the card into a Nintendo Switch, and what step do users often miss?

Power off the console, open the kickstand cover, insert the card label-side up until it clicks, then close the cover before powering on.

When should the card be replaced if used for daily 4K recording on a GoPro?

Replace the card if write speeds drop below 30 MB/s, if the camera reports card errors, or after several years of continuous daily recording.
