What this card is and who it fits

The Team Group APEX microSD Express card delivers 256 GB of storage using the SD 7.1 standard with a PCIe Gen3 x1 lane and NVMe 1.3 protocol. It targets owners of next-generation handheld consoles such as the Nintendo Switch 2 who need faster load times and quick access to large game libraries. The card also carries an A1 application performance rating for smooth app operation.

Installation ease and common pitfalls

The card uses the familiar microSDXC form factor measuring 72 x 24 x 4.6 mm and weighs 1 g, so it slides into any microSD slot without tools or drivers. Full SD Express speed requires a host device with an SD 7.1 compatible controller; in older UHS-I only devices the card falls back to 100 MB/s read and 90 MB/s write. No extra power or firmware steps are needed.

Practical limits of the SD Express interface

Maximum sequential reads reach 800 MB/s and writes reach 700 MB/s when paired with a professional card reader or a console that implements the full SD 7.1 specification. In legacy UHS-I mode the ceiling drops to 100 MB/s read and 90 MB/s write. Operating temperature range is 0 °C to 70 °C and storage range extends to -40 °C to 85 °C at 2.7 V to 3.6 V.

Questions about this item

How can I verify the card is reaching its 800 MB/s read speed after setup?

Use a professional SD Express card reader and benchmark tool to confirm read speeds up to 800 MB/s and write speeds up to 700 MB/s.

What comes in the box and do I need a special reader for full speed?

The package contains the 256 GB microSDXC card only; a professional SD Express card reader must be purchased separately to achieve 800 MB/s read and 700 MB/s write.

Which capacity should I choose among the 128 GB, 256 GB, 512 GB and 1 TB versions?

All capacities share the same 800 MB/s read and 700 MB/s write ratings, so pick the size that matches your storage budget and game library needs.
