Capacity and intended use

The SanDisk Extreme Pro SDXC card provides 512GB of storage for cameras and devices that accept full-size SD media. It targets photographers and videographers who need sustained write performance for 4K UHD recording and sequential burst shooting. The U3 and V30 ratings guarantee a minimum write speed of 30MB/s for uninterrupted capture. Buyers who need more storage or faster sustained writes for higher bitrate formats should consider other options.

UHS-I bus limits

The card operates on the UHS-I interface, delivering read speeds up to 170MB/s and write speeds up to 90MB/s. These figures represent the practical ceiling of the single-lane UHS-I bus, so transfer times will not exceed this bandwidth. Host devices must support UHS-I to achieve the rated performance; older readers will fall back to lower speeds. Workflows that demand higher throughput than the UHS-I maximum will not benefit from this card.

Durability and daily handling

The card is built for harsh conditions with temperature-proof, waterproof, shock-proof and X-ray-proof construction. This ruggedisation protects data during outdoor shoots, travel and security screening. The standard full-size SD form factor fits directly into compatible cameras, laptops and readers without adapters. Users with devices that only accept microSD will need a separate adapter, which is not included.

Questions about this item

Which capacity of the SanDisk Extreme Pro SDXC UHS-I card should I choose for 4K UHD video and burst photography?

The 512GB model gives ample space for extended 4K UHD recording and long sequential burst sessions without frequent card swaps.

What does the 170MB/s read speed mean when I offload footage to my workstation?

You can transfer large 4K files and RAW bursts at up to 170MB/s, cutting ingest time dramatically compared with slower cards.

How does the UHS-I interface affect the 90MB/s write rating in camera?

The card is rated for up to 90MB/s write, which the UHS-I bus supports for sustained 4K UHD capture.
