DATO Express 512GB microSDXC NVMe memory card

512 GB microSD Express card

The DATO Express 512 GB microSDXC Express card uses a PCIe Gen3 x1 interface with NVMe protocol to deliver SSD-class throughput in the standard microSD form factor. It targets creators and gamers who need fast removable storage for 4K or 8K capture and large game libraries. Backward compatibility with UHS-I hosts lets it operate in existing slots at reduced speed. Buyers whose devices lack microSD Express support will not see the advertised peak rates.

Thermals noise and power draw

The card weighs 1 gram and measures 0.59 by 0.43 inches, so it adds negligible mass and fits tight slots without blocking adjacent ports. No moving parts mean silent operation and no fan noise under any workload. Power is drawn directly from the host slot; the low-profile design keeps thermal output minimal during typical file transfers or video recording sessions.

Sustained load behaviour

Sequential read reaches up to 800 MB/s and write up to 700 MB/s on microSD Express hosts, while UHS-I hosts deliver up to 280 MB/s read and 180 MB/s write. U3, V30 and A1 ratings guarantee minimum sustained performance for 4K/8K video and app loading. Thermal throttling may reduce speeds during extended maximum-throughput writes, but the card maintains rated class minimums for the duration of the recording or transfer.
