Delkin Power 64GB SDXC UHS-II Memory Card - Fast V90 Performance

In this review of the Delkin Power 64GB SDXC UHS-II card, the bottom line is simple: it is aimed at photographers and videographers who need sustained, high-speed recording for modern video formats and burst RAW shooting. The most compelling reason to buy is its combination of a V90 rating with real-world write speeds reported up to 250MB/s and read speeds to 300MB/s, which makes it reliable for 8K, 4K, HDR and 360 video workflows. For those prioritizing fast offloads and uninterrupted recording, this card consistently delivers.

Key Features

• High-speed read/write: Read speeds up to 300MB/s and write speeds to 250MB/s let you offload large files quickly and reduce downtime between shoots.
• Video Speed Class V90: A minimum sustained write speed of 90MB/s supports uninterrupted recording of high-resolution video and simultaneous multi-file streams.
• Optimized for professionals: Designed for continuous burst RAW photography and high-frame-rate video, it suits DSLR, mirrorless and UHS-II compatible cameras.
• Durable build: The card is shockproof, water-resistant and X-ray proof, giving confidence when working in demanding field conditions.
• Streamlined workflow: Fast read performance supports quicker transfers so editors and shooters can move to the next task without long waits.
• Warranty and support: Lifetime Warranty plus a 48-hour replacement guarantee for manufacturer defects provides added peace of mind.

Who It's For

This card is best for professional photographers and videographers using cameras that can exploit UHS-II bandwidth, especially when shooting 8K, 4K, HDR, 3D or 360 video and when continuous burst RAW capture is required. It also fits content creators who need fast offload speeds to keep a tight production schedule.

Casual users or those with older cameras that do not support UHS-II may not see the full benefit of the higher speed class and might prefer a lower-cost option. If extreme card longevity is your single top priority, mixed customer feedback on longevity suggests monitoring long-term use closely.
