Extreme Pro UHS-II SDXC Memory Card, 64GB

SanDisk Extreme Pro UHS-II SDXC 64GB — Extended Buffer for High-Bitrate Production Days

The gist: Double the capacity of the 32 GB model with identical V90 / UHS-II specs — the practical choice for videographers who shoot extended client sessions and need one card to last a full production day without an interrupting swap.

• 64 GB V90 capacity: Holds roughly 80+ minutes of high-bitrate 4K RAW before offload is needed — covering a full brand shoot, documentary day, or corporate event on a single card.
• 260 MB/s write prevents buffer stalls: V90 sustained minimum keeps data flowing at the rates that cameras like the Sony A1 or Nikon Z9 demand during continuous high-bitrate recording — no pauses, no missed moments.
• 300 MB/s ingest to editing rig: Full 64 GB offloads in roughly four minutes via a UHS-II reader — maintains tight turnaround on same-day edit deliverables.
• Better cost per GB than 32 GB: At ~$60 for 64 GB vs. ~$45 for 32 GB, the larger card delivers more storage per dollar while running the same professional V90 spec.

SanDisk’s official SDSDXDK product page confirms the V90 Video Speed Class rating and 300 MB/s read specification apply across all capacities in the Extreme Pro UHS-II SDXC line.

Best for: Cinematographers, documentary videographers, and studio production teams running UHS-II camera bodies who need to minimize card swaps during critical recording windows. Skip it if: Your workflow shoots to CFexpress or XQD — a card reader and media type mismatch means this card won’t fit. Runs ~$60 — check the current price before buying.
