SanDisk pushes the envelope with its newest Extreme PRO CFexpress 4.0 Type B cards, offering capacities from 128 GB to a staggering 4 TB. Targeted at professional video workflows, the line supports 12K resolution and delivers up to 3,700 MB/s reads and 3,500 MB/s writes thanks to a PCIe Gen 4 interface.

Performance varies by size. The 2TB and 4TB models sustain up to 3,100 MB/s writes, while the 1TB variant reaches 1,950 MB/s. Lower‑capacity cards hit about 900 MB/s. Larger SKUs carry VPG1600 certification; smaller ones qualify for VPG800 or VPG400, matching their burst capabilities. Thus, the 4TB unit can sustain 8K recording for hours without throttling and maintaining performance.

Durability matches speed. Cards survive 5‑meter drops and 70 N bend forces, making them suitable for on‑set use. SmartIdle trims heat by cutting power during idle periods, extending battery life on drones and handheld rigs. Prices begin at $249.99 for 128 GB and climb to $1,799.99 for the 4 TB model, all backed by a lifetime warranty today.

For videographers chasing the next visual frontier, SanDisk’s Extreme PRO CFexpress 4.0 cards offer the only combination of raw throughput, massive capacity, and rugged resilience. With a clear price ladder and industry‑certified performance, the line positions itself as the go‑to storage for 12K and beyond, replacing older CFexpress and SD cards on professional rigs today.
