SKU: SDSDXVV-512G-GNCIN

Overview

The SanDisk SDSDXVV-512G-GNCIN 512GB Extreme SDXC UHS-I card is built for photographers and videographers who need reliable, high-speed storage without stepping up to the cost of UHS-II media. With read speeds up to 180MB/s powered by SanDisk's proprietary QuickFlow Technology and write speeds reaching 130MB/s, this card handles rapid burst shooting and sustained 4K UHD video recording with confidence. The V30 and U3 speed class ratings guarantee a minimum sustained write speed of 30MB/s, ensuring smooth, uninterrupted capture even during demanding recording sessions.

The card is well-suited for content creators, travel photographers, and event shooters who need a large, fast, and dependable memory card that works across a broad range of SDXC-compatible cameras and devices.

Frequently Asked Questions

What does SanDisk QuickFlow Technology do on this card?

QuickFlow Technology enables read speeds up to 180MB/s, which is beyond the standard UHS-I 104MB/s specification. It requires a compatible device to achieve these speeds and is available on the 64GB through 512GB capacities of this card.

Can this card record 4K UHD video continuously?

Yes. The SDSDXVV-512G-GNCIN is rated UHS Speed Class 3 (U3) and Video Speed Class 30 (V30), which means it sustains a minimum 30MB/s write speed — sufficient for uninterrupted 4K UHD video capture on compatible cameras.

How much usable storage does the 512GB card actually provide?

Formatted capacity will be somewhat less than 512GB because the manufacturer measures 1GB as 1,000,000,000 bytes, while operating systems use 1,073,741,824 bytes. Expect roughly 465–477GB of usable space after formatting.

Is this card compatible with the SanDisk Professional PRO-READER?

Yes. Pairing it with the SanDisk Professional PRO-READER SD and microSD reader (sold separately) allows you to take full advantage of the card's maximum transfer speeds during offloading.

What is the write speed of this card?

The card offers write speeds up to 130MB/s, which is also beyond the standard UHS-I specification and requires a compatible host device to reach.
