SanDisk SDSDXVA-128G-GNCIN 128GB Extreme SDXC UHS-I Card 4K

Name: SanDisk SDSDXVA-128G-GNCIN 128GB Extreme SDXC UHS-I Card 4K
Brand: SanDisk
SKU: SDSDXVA-128G-GNCIN

Overview

The SanDisk 128GB Extreme SDXC UHS-I card is built for photographers and videographers who need dependable high-speed performance without stepping up to the premium price tier. With read speeds reaching up to 180MB/s thanks to SanDisk's proprietary QuickFlow Technology, offloading large batches of RAW photos or lengthy 4K video clips becomes significantly faster than with standard UHS-I cards. Write speeds of up to 90MB/s keep pace with sequential burst shooting and continuous 4K UHD recording, backed by U3 and V30 speed class ratings that guarantee a minimum sustained write throughput of 30MB/s.

The 128GB capacity strikes a practical middle ground — large enough to hold thousands of high-resolution photos or hours of 4K footage, yet priced accessibly enough to keep multiples in your kit bag. The card is designed for use in DSLR and mirrorless cameras, action cameras, drones, and other devices with full-size SD card slots. For maximum transfer speeds when moving files to a computer, SanDisk recommends pairing the card with their Professional PRO-READER SD reader, which is optimized to work with QuickFlow Technology. It is a well-rounded choice for creators who want fast, reliable storage without overspending.
