Capacity and class

This is a 512GB SanDisk Extreme Pro SDXC card rated UHS-I U3 V30 A2. It targets photographers and videographers who need sustained write performance for 4K UHD capture. The card delivers read speeds up to 250MB/s and write speeds up to 170MB/s. It is built to withstand harsh conditions during extended shoots.

Who benefits and who does not

Creators recording 4K UHD at 30 fps or shooting high-resolution bursts will appreciate the V30 guarantee and A2 app performance. Users requiring faster sustained write speeds for higher bitrate codecs or 8K workflows should consider cards with higher video speed class ratings. The UHS-I interface also limits maximum throughput compared to UHS-II or UHS-III alternatives.

Deciding specification

The V30 rating guarantees a minimum sustained write speed of 30MB/s, which is the critical figure for uninterrupted 4K UHD video recording. If your camera demands a higher minimum write speed, this card will not meet that requirement. Verify the required video speed class before purchasing.

Questions about this item

Does my camera need an SDXC slot to use this 512GB card?

Yes, the card is SDXC format and requires a host device with an SDXC-compatible slot.

Will this UHS-I card deliver its 170MB/s write speed in my older UHS-I camera?

It will operate at up to 170MB/s write speed provided the camera supports UHS-I; older non-UHS hosts will fall back to lower speeds.

How can I confirm the card is sustaining V30 performance after formatting?

Record a 4K UHD clip at 30 fps and verify continuous writing without dropped frames; the V30 rating guarantees minimum 30MB/s sustained write.
