  • Store up to 1TB of games and media
  • U3 and V30 ratings deliver smooth 4K video capture

High-capacity microSD for handheld gaming

The Patriot Viper 1TB microSD card delivers expansive storage for handheld consoles and mobile devices. It carries UHS Speed Class 3, Video Speed Class V30 and Application Performance Class A2 ratings. Read speeds reach 100MB/s and write speeds reach 90MB/s. The card is designed to hold large game libraries and high-resolution media.

Ideal for Switch, Steam Deck and ROG Ally owners

This card suits gamers who want a single high-capacity card for a Nintendo Switch, Steam Deck or ROG Ally. It also fits smartphones and tablets that accept microSDXC. Buyers who need more than 1TB of removable storage should look at alternative solutions. The UHS-I bus limits peak throughput, so workflows demanding sustained speeds above the quoted figures will not be satisfied.

V30 and A2 ratings guarantee minimum sustained write

The V30 rating ensures a minimum sequential write speed of 30MB/s for 4K video capture. The A2 rating provides higher random read and write IOPS for faster game loading and app performance. These two specifications together determine whether the card meets the performance floor required by modern handheld consoles.

Questions about this item

Does the 100 MB/s read speed generate noticeable heat during extended recording sessions?

The card uses a passive UHS-I interface with no moving parts, so heat output remains minimal even at sustained 100 MB/s reads.

Which host devices must already support UHS-I U3 V30 A2 for this card to work?

Any device with a microSDXC slot that meets UHS-I, Class 10, U3, V30 and A2 ratings — such as Nintendo Switch, Steam Deck or ROG Ally — will recognise the full 1 TB capacity.

Will the 90 MB/s write speed drop when used in an older Class 10-only camera?

In a Class 10-only host the card falls back to 10 MB/s minimum sustained write, so 4K capture at V30 rates is not supported.
