512GB microSDXC card for 4K capture

The Samsung PRO Plus MB-MD512KA/AM is a 512GB microSDXC card rated UHS-I U3 Class 10 A2 V30 with sequential reads up to 160MB/s and writes up to 120MB/s. It includes a full-size SD adapter and carries six-proof protection against water, temperature extremes, X-rays, magnetic fields, drops and wearout. The card targets phones, drones, tablets and handheld gaming devices that need sustained 4K video recording and fast app loading.

Suited for 4K workflows; not for higher-speed buses

Creators capturing 4K footage on UHS-I hosts will benefit from the V30 sustained write rating and A2 random performance for installed applications. The bundle works well for expanding storage on compatible mobile devices and action cameras. Buyers whose cameras or readers support UHS-II or UHS-III interfaces will not reach those bus speeds with this card, and users needing capacities beyond 512GB should consider larger media.

512GB capacity with V30 headroom

The 512GB capacity holds hours of 4K video and large game libraries while the V30 rating guarantees at least 30MB/s sustained write for continuous recording. Peak writes of 120MB/s clear the buffer quickly during burst shooting. Workflows that demand sustained writes above 30MB/s or require UHS-II throughput will exceed what this UHS-I card can deliver.

Questions about this item

What device slot is required to use the 512GB microSDXC card?

The card fits any device with a microSDXC slot that supports UHS-I and the U3, Class 10, A2 and V30 speed ratings.

Will the included SD adapter work in an older SDHC-only card reader?

The adapter provides full-size SD mechanical compatibility, but the host must support SDXC capacity and UHS-I speeds to reach the rated 160MB/s read and 120MB/s write performance.

How can I confirm the card is delivering its rated speeds after setup?

Run a sequential read/write benchmark such as CrystalDiskMark or Blackmagic Disk Speed Test and verify results approach 160MB/s read and 120MB/s write on a UHS-I host.
