SanDisk Extreme Pro 64GB UHS-I U3 SDXC Memory Card 2-Pack with Card Reader

SKU CH-X1W2-QYASY

Two 64 GB UHS-I U3 cards deliver up to 200 MB/s read and 90 MB/s write for 4K UHD video, bundled with a USB-C reader

  • Capture 4K UHD video smoothly with 140MB/s shot speeds
  • Transfer files faster at up to 200MB/s read speed
  • Store extensive media libraries on two 64GB cards
  • Protect data against weather water and shocks
  • Speed up post-production workflow with included USB-C card reader

Two-Card Kit for High-Resolution Capture

This bundle pairs two 64GB SanDisk Extreme Pro SDXC cards with a USB Type-C card reader, giving photographers and videographers a ready-to-shoot package for extended 4K UHD sessions. Each card carries a UHS Speed Class 3 (U3) rating, supporting sustained write performance for uninterrupted recording. The included reader connects directly to modern laptops and workstations without an adapter.

QuickFlow Offload and U3 Recording Support

The supplied QuickFlow SD USB Type-C reader enables media offloads at up to 90MB/s sequential transfer, reducing post-production wait times. On the cards themselves, shot speeds reach 140MB/s for fast burst photography, while sequential read peaks at 200MB/s when paired with compatible readers. UHS-I U3 specification guarantees the minimum write throughput required for stutter-free 4K UHD video capture.

Weather-Resistant Build

Cards are engineered to withstand weather, water, shocks and other harsh conditions encountered during location work. The bundled reader uses a USB Type-C plug, eliminating the need for separate cables or legacy USB-A ports on current devices. Buyers who need capacities beyond 64GB per card or who require UHS-II interface speeds will need a different product.

Questions about this item

How often will I need to replace these 64GB UHS-I U3 cards under heavy 4K video use?

The cards are built to withstand weather, water and shocks, and carry a SanDisk Lifetime Limited Warranty, so replacement is only needed if physical damage occurs or capacity is exceeded.

What speed ceiling appears first during long 4K UHD recording sessions?

Sustained write performance is rated at 90MB/s, which is the limiting factor for continuous 4K capture before the buffer fills.

How much heat or noise does the bundle produce when the reader transfers 64GB cards all day?

The bundle has no moving parts or fan; the cards and USB-C reader run silently and generate only minimal warmth during extended transfers.
