High-capacity microSDXC card for everyday use

The Samsung T7 microSD MB-MB512T is a 512GB microSDXC card built for casual gamers, amateur creators and everyday users. It fits smartphones, tablets, handheld consoles, laptops and cameras, giving ample room for photos, 4K video and game libraries. The bundled adapter extends compatibility to full-size SD slots.

UHS-I interface limits sustained throughput

The card uses the UHS-I bus, so maximum read speed is capped at 170 MB/s regardless of the host device. Write speeds will be lower than the peak read figure and vary with the device controller. U3 and V30 ratings guarantee a minimum 30 MB/s sequential write for stable 4K recording, while A2 rating improves random I/O for app loading.

512GB capacity decides suitability

The single specification that determines fit is the 512GB capacity. Users who need more storage for large media libraries or extensive game collections will require a higher-capacity card. Buyers with lighter storage demands may find a smaller card more cost-effective.

Questions about this item

Should I choose the 512GB model or a smaller 128GB card?

The 512GB model gives four times the space of the 128GB version, so you can keep a large game library, hours of 4K footage or thousands of hi-res photos without swapping cards.

What does the 170 MB/s read speed mean when I am actually moving files?

You can expect fast transfers when offloading 4K video or game installs to a PC; the card is rated for up to 170 MB/s read, so large folders copy in seconds rather than minutes.

How does the UHS-I U3 V30 rating affect real-world recording?

U3 and V30 certify a 30 MB/s minimum sustained write speed, which keeps 4K video recording stable without dropped frames.
