128GB SDXC Card for Professional Capture

This SanDisk Extreme SDXC card provides 128GB of storage for professional photographers and videographers. It supports 4K UHD video recording and high-resolution sequential burst photography. The UHS Speed Class 3 (U3) and Video Speed Class 30 (V30) ratings guarantee sustained performance for demanding creative workflows. It is built for reliability in challenging shooting environments.

UHS-I Interface Limits at 180MB/s Read

The card operates on the UHS-I interface with maximum read speeds of 180MB/s and write speeds of 90MB/s. This bus standard caps the theoretical throughput below faster UHS-II or UHS-III alternatives. SanDisk QuickFlow Technology helps accelerate media offloads when paired with compatible readers. The practical ceiling suits 4K workflows but not 8K or high-bitrate RAW video pipelines.

Upgrade from Slower Class 10 or U1 Cards

This card replaces standard Class 10 or UHS Speed Class 1 (U1) media that cannot sustain 4K recording or fast burst clearing. The jump is worth it when your camera supports UHS-I U3/V30 and you need 90MB/s write speeds to avoid buffer bottlenecks. It is not for devices limited to UHS-I U1 speeds or workflows requiring UHS-II write performance.

Questions about this item

Should I choose the 128 GB version or a larger capacity?

The 128 GB model gives enough room for long 4K UHD sessions and high‑resolution bursts; pick a bigger card only if you regularly fill a full card in one shoot.

What does the 90 MB/s write speed mean when I am shooting?

It lets the camera clear its buffer fast enough for continuous 4K UHD recording and rapid sequential bursts without stalling.

How does the UHS‑I interface affect the 180 MB/s read claim?

UHS‑I is the bus used by this card; the 180 MB/s read figure is the rated maximum the card can deliver over that interface when paired with a compatible reader.
