Customer Reviews (5.0 / 5 · 5 reviews)

Ruby U. ★★★★★

Was skeptical about the price, but the sustained write speed for my 8K RAW files is genuinely impressive—no dropped frames whatsoever. It transfers a full 128GB card to my computer in about a minute through my USB-C reader.

Sebastian G. ★★★★★

Pulled it out of the camera and the transfer speeds to my computer are noticeably faster than my previous card, saving me real time on set. The 128GB capacity is enough for a full day of 8K footage without needing to offload.

Michael K. ★★★★★

I've been using this card for my daily 6K shoots and the sustained write speeds are real—never once had a dropped frame. The transfer time when offloading over USB-C is ridiculous, cuts my workflow in half.
