512 GB microSDXC card for mobile and action devices

This Samsung Micro SD T7 card provides 512 GB of storage in the microSDXC format. It is built for mobile phones, tablets, action cameras, 360° cameras, drones, laptops and gaming consoles. The UHS-I interface works with devices that support the UHS standard. Buyers who need more than 512 GB of capacity should consider higher-capacity cards.

Thermal and power behaviour in daily use

The card operates between -13 °F and 185 °F and survives storage temperatures from -40 °F to 185 °F. It draws power at 2.7 V to 3.6 V during normal operation. With no moving parts the card runs silently and adds negligible heat to the host device. It is rated for 10,000 mating cycles for long-term connector reliability.

U3, V30 and A2 speed class for sustained write

Sequential read speeds reach up to 170 MB/s. The U3 and V30 ratings guarantee a minimum sustained write speed of 30 MB/s for 4K video capture. The A2 rating supports faster app loading and random I/O on compatible devices. Cards without these speed classes may drop frames or slow down during continuous recording.

Questions about this item

How do I insert the microSDXC card into my device and which orientation mistake should I avoid?

Align the gold contacts facing down and the notched corner toward the slot; forcing it upside-down can damage the 10000 mating-cycle connector.

What maintenance or replacement will this card need over time?

No scheduled maintenance is required; the card is rated for 10000 mating cycles and operates from -13°F to 185°F, so replacement is only needed if physical wear or capacity limits are reached.

What is the first performance limit I will hit during sustained 4K video recording?

The V30 speed class guarantees a minimum 30 MB/s sequential write, which is the bottleneck before the 170 MB/s read ceiling becomes relevant.
