Capacity and speed
The ALSEYE 256GB microSDXCEX card delivers sequential read speeds up to 800MB/s and write speeds up to 700MB/s. It uses a PCIe Gen3x1 NVMe interface while maintaining UHS-I backward compatibility. Rated C10, U3, V30 and A1, it supports 4K and 8K video recording.
Who it suits
Creators capturing 4K or 8K footage, drone and action-camera operators needing sustained write performance, and Switch 2 owners seeking faster load times will benefit. Buyers whose devices only support standard UHS-I microSD cards will not see the advertised transfer rates.
Deciding specification
The PCIe Gen3x1 NVMe interface is the single factor that unlocks the 800MB/s read and 700MB/s write ceiling. Without a microSD Express compatible host the card falls back to UHS-I speeds, so verify your device supports the Express standard before purchasing.

Questions about this item
How do I verify the card reaches the 800 MB/s read speed after setup?
Insert the card into a microSD Express-compatible host, then run a sequential-read benchmark such as CrystalDiskMark; a result near 800 MB/s confirms the PCIe Gen3x1 NVMe link is active.
What accessories are included and what must I purchase separately?
The package contains the 256 GB microSDXCEX card and a full-size SD adapter; a microSD Express card reader or a device with a native microSD Express slot is required for full speed and is sold separately.
Which capacity should I choose for 4K 8K recording on a Switch 2?
The 256 GB model provides roughly 30 minutes of 8K footage or several hours of 4K, making it the smallest capacity that balances recording time and cost for that console.
