All good. Sequential read/write: 300/300 MB/s

Working perfectly,

I’ve been using the SanDisk 128GB Extreme PRO (V90) SD card for a few months now, and it's honestly in a league of its own. If you're working with high-bitrate 4K or even 8K footage, or shooting high-speed RAW bursts, this card will keep up without breaking a sweat. Speed & Performance: With read and write speeds up to 300MB/s, this card is insanely fast. I use it with my Canon R10, and I’ve never hit a buffer wall, even when shooting extended bursts in RAW. Offloading files to my MacBook Pro is lightning quick, making post-production workflows far more efficient. The V90 speed rating guarantees sustained performance, which is crucial when shooting high-resolution video with no dropped frames. Reliability: SanDisk has always been my go-to for dependable storage, and this card holds up in every condition I’ve tested—hot, cold, dusty, and even slightly wet environments. Zero data loss, no glitches, and smooth performance every time. Capacity: 128GB is the perfect size for a full day of shooting high-res content. I can shoot 4K/8K video or hundreds of RAW images without worrying about swapping cards. Build Quality: Solid, professional-grade build. It’s shockproof, temperature-proof, waterproof, and X-ray-proof—exactly what I want when shooting outdoors or traveling. Final Verdict: If you’re a serious photographer or videographer who needs top-tier speed and rock-solid reliability, this SanDisk Extreme PRO V90 card is 100% worth the investment. It’s built for professionals—and it delivers. Highly recommended without hesitation!

Amazing card. The best.
