Samsung PRO Plus 512GB microSDXC

The Samsung PRO Plus MB-MD512SA/AM is a 512GB microSDXC memory card rated UHS-I, U3, Class 10, A2 and V30. It delivers sequential read speeds up to 180MB/s and write speeds up to 130MB/s. The card ships with a full-size SD adapter for broader device compatibility.

Creators needing sustained 4K video capture

The V30 and A2 ratings suit creators recording 4K footage and users running apps directly from the card. The six-proof protection handles water, temperature extremes, X-rays, magnets, drops and wearout. Buyers needing capacities beyond 512GB or faster UHS-II performance should consider other options.

UHS-I interface with 180MB/s read and 130MB/s write

The single specification that decides fit is the UHS-I interface combined with 180MB/s read and 130MB/s write speeds. Devices limited to UHS-I bus speeds will realise these rates. Hardware requiring UHS-II or higher throughput will not reach its potential with this card.

Questions about this item

Does this microSDXC card require a host device with a microSDXC slot to use its 512GB capacity?

Yes, the card is a microSDXC type and needs a device that supports the microSDXC standard to access the full 512GB capacity.

Will the included SD adapter let me use this card in an older laptop that only has a full-size SD slot?

The bundled SD adapter converts the microSDXC card to full-size SD form factor, so it fits standard SD slots on older laptops and readers.

How can I confirm the card is delivering its rated 180MB/s read and 130MB/s write performance after setup?

Run a benchmark tool such as CrystalDiskMark on a UHS-I capable reader; sequential results should approach 180MB/s read and 130MB/s write.
