512 GB microSDXC card for mobile and action cameras

The Samsung EVO Plus MB-MC512KA is a UHS-I microSDXC card rated at 512 GB capacity. It carries U3, Class 10, V30 and A2 speed ratings with a maximum read speed of 130 MB/s. The card includes a full-size SD adapter for use in cameras, laptops and card readers. It is suited to phones, tablets, drones and action cameras that accept microSDXC media.

Ideal for expanding phone storage

This card suits users who need more space for apps, photos and 4K footage on a single device. The A2 rating helps apps launch and run smoothly from the card. Buyers whose devices only support microSDHC or lack UHS-I support will not see the rated performance. Anyone requiring sustained write speeds above the V30 guarantee should consider cards with higher video speed class ratings.

UHS-I interface with 130 MB/s maximum read speed

The single specification that decides fit is the UHS-I bus combined with a 130 MB/s read ceiling. If the host device supports UHS-I, the card will deliver its rated transfer rates for large files and 4K recording. If the host is limited to older bus modes, actual throughput will be lower.

Questions about this item

What does the 130 MB/s read speed mean when the card is used in a phone or camera?

The 130 MB/s rating is the maximum sequential read speed under UHS-I; real-world throughput depends on the host device and file sizes.

How does the UHS-I interface with U3, V30 and A2 ratings affect performance?

UHS-I sets the bus standard; U3 and V30 guarantee a minimum 30 MB/s sustained write for 4K video, while A2 certifies faster app loading on Android.

What do I need to fit this card and the included adapter into my devices?

The microSDXC card fits any microSDXC slot; the bundled full-size SD adapter lets you use it in standard SDXC readers and cameras.
