Professional content capture

The PNY EliteX-PRO90 is a 256GB UHS-II SDXC memory card built for professional photographers and videographers. It carries Class 10, U3 and V90 ratings to handle the most demanding write-intensive workflows. The card supports uninterrupted 8K Ultra HD video capture at 7680 x 4320 resolution as well as 4K and Full HD recording.

Thermals noise and power

As a solid-state memory card it has no moving parts, fans or active cooling requirements. It operates silently and draws negligible power from the host camera or reader. The card is rated magnet proof, shock proof, temperature proof and waterproof for reliable operation in harsh environments.

Build integration and workflow

The card fits any UHS-II enabled DSLR, mirrorless or advanced video camera and falls back to UHS-I speeds in older slots. Read speeds up to 300MB/s and write speeds up to 280MB/s accelerate ingest and post-production editing. V90 guarantees a minimum sustained 90MB/s for extended cinema-quality capture. It does not serve buyers who need larger capacities or alternative form factors such as CFexpress or microSD.

Questions about this item

How do I insert the EliteX-PRO90 into my UHS-II camera slot without damaging the second row of contacts?

Align the card label-side up with the angled corner matching the slot, then slide it in until it clicks. The extra row of pins on UHS-II cards sits deeper; forcing it sideways bends those contacts and drops speeds to UHS-I levels.

Will the V90 rating on this 256GB card degrade over time, and when should I replace it?

The V90 mark guarantees a minimum sustained write of 90MB/s for the card’s usable life. Replace it if sustained write benchmarks fall below 90MB/s or if the camera reports write errors during 8K recording at 7680 x 4320.

What is the first bottleneck I will hit when recording long 8K clips continuously?

The card’s sustained write floor of 90MB/s is the limiting factor. While burst peaks reach 280MB/s, extended 8K capture at 7680 x 4320 will throttle to that 90MB/s minimum once the internal buffer fills.
