SanDisk Extreme 128GB SDXC Memory Card

180MB/s QuickFlow · 90MB/s Write

Fast Transfer · Sustained 4K Capture

180MB/s sequential read transfers a full 128GB card to a laptop in approximately 12 minutes, compared to over 20 minutes at the standard UHS-I 104MB/s ceiling. SanDisk QuickFlow Technology achieves this by engineering around the UHS-I interface limit rather than being capped by it — pairing with a compatible reader such as the SanDisk Professional PRO-READER unlocks the full 180MB/s. 90MB/s write sustains 4K UHD recording at 30fps on compatible cameras and handles extended RAW burst sequences without the camera’s internal buffer saturating. V30 (Video Speed Class 30) guarantees a minimum 30MB/s sustained write at all times — the minimum specification for reliable, uninterrupted 4K video recording on any V30-rated camera. U3 confirms the same minimum for UHS-rated devices.

Full-Size SD · Write-Protect Switch

Direct Camera Fit — No Adapter Needed

The SanDisk Extreme 128GB is a full-size SDXC card — the standard format used in the vast majority of DSLRs, mirrorless cameras, camcorders and hybrid cameras. It inserts directly into the camera’s SD card slot without an adapter. This matters in professional use: there is one less component to lose, one less failure point, and no risk of a microSD card becoming dislodged from a loose adapter. The mechanical write-protect switch on the side of the card locks the card into read-only mode when slid into the protect position. This prevents the camera from accidentally formatting the card or the computer from deleting files when connected via a card reader — a practical safeguard for cards holding an entire day’s irreplaceable shooting.

4-Proof + RescuePRO Deluxe

Field-Ready — Recovery Software Included

Shock, temperature, waterproof and X-ray resistant construction addresses the conditions that cameras and SD cards encounter in outdoor use — rain during a wedding shoot, temperature changes between a cold morning and a warm venue, airport security X-ray scanning, and the occasional dropped camera bag. RescuePRO Deluxe data recovery software is included as a download code and can restore accidentally deleted photos and videos from the card. For photographers working through a 128GB card in a single shoot, the ability to recover accidentally deleted material from earlier in the day without leaving the location is a practical and meaningful safety net. The lifetime SanDisk warranty covers manufacturing defects for the life of the product.
