Professional 128GB SDXC UHS-II Card

This Lexar Professional card delivers 128GB of storage for photographers and videographers who need reliable capacity. It supports 1080p full-HD, 3D and 4K video capture alongside high-quality stills. The UHS-II interface enables fast data transfer back to a workstation.

UHS-II Speed Class 3 Performance

Read speeds reach 150MB/s at 1000x rating while write performance meets UHS Speed Class 3 (U3) for sustained recording. The card draws power directly from the host device with no external supply required. Silent solid-state operation adds no acoustic noise to the shooting environment.

UHS-II Host Compatibility

The card requires a UHS-II capable slot to achieve the quoted 150MB/s read speed; older UHS-I readers will fall back to lower rates. It frees up internal camera buffer space during burst shooting and long video takes. No additional cables, adapters or software drivers are needed for standard operation.

Questions about this item

How do I install the Lexar Professional 128GB 1000x SDXC UHS-II Card, and what step do people often miss?

Insert the card label-side up into your device's UHS-II slot until it clicks; the step users miss is confirming the host device supports UHS-II to reach the 150MB/s read speed.

What maintenance or replacement will this 128GB card need over time?

No scheduled maintenance is required; keep contacts clean and avoid extreme heat. Replace the card if write errors appear or after heavy 4K video workloads wear the NAND.

What limit appears first during sustained 4K recording on this U3-rated card?

The sustained write capability of the U3 class is the first bottleneck; the 150MB/s figure applies to read transfers, not continuous write throughput.
