  • SD Express 7.1 with PCIe Gen 3x1 and NVMe delivers up to 880MB/s read speed
  • Up to 700MB/s write speed cuts game load times, 2.7× faster than UHS-II cards
  • Dual PCIe Gen 3x1 and UHS-I interfaces work with new and previous generation consoles

  • V30 video standard supports smooth 4K UHD capture and playback

Built for Nintendo Switch 2

This 256 GB microSDXC Express card uses the SM2708 chip with SD Express 7.1, PCIe Gen 3x1 and NVMe protocol. It targets Nintendo Switch 2 owners who need faster game loading and 4K video capture in a compact form factor.

Thermals and power in normal use

The card operates from 0°C to 70°C without performance loss. Dual PCIe Gen 3x1 and UHS-I interfaces maintain compatibility across console generations while drawing power directly from the slot.

Upgrade path and when it matters

It replaces UHS-II microSD cards and delivers up to 2.7x faster read speeds. The jump is worth it when installing large AAA titles or recording 4K UHD video at V30 on Switch 2.

商品問答

Will this card reach its top speed in my original Nintendo Switch?

The card falls back to UHS-I on the original Switch so speeds will be limited to that interface rather than the quoted 880 MB/s read or 700 MB/s write.

Is the 256 GB capacity enough for several large Switch titles?

256 GB holds multiple AAA games plus 4K video clips; larger 512 GB and 1 TB versions exist if you need more space.

Does the V30 rating guarantee smooth 4K recording on Switch 2?

V30 certifies a minimum 30 MB/s sustained write which meets the baseline for 4K UHD capture on the console.
