Review on 💯 Prograde Digital SD UHS-II 128GB Card V60: Boost Your Workflow with Lightning-Fast Write and Read Speeds – Ideal for Vloggers, Filmmakers, Photographers, and Content Curators by David Dortch

My new Fujifilm GFX 50S creates huge files. 120-150MB per RAW image file is huge. I've had pairs of 64GB UHS-II SD cards from Sony, SanDisk, and Lexar and haven't had any issues with speed, reliability, or longevity. Although they hold around 500 frames when shooting in RAW with only a second card backup, my wanderings are sometimes long and I knew I would be more comfortable with more space. Yes, some people recommend using more cards, but I would prefer not to change cards in the field due to the risk of losing them through drops or static electricity. I also don't want to carry around more gear than I need, so throwing Gnarbox into the mix isn't an option. The best solution for me was to just buy some bigger cards. Speed is of the essence with image files of this size. While these aren't the fastest cards ProGrade has to offer, their write speeds are still faster than their second-tier counterparts from all the brands mentioned above, as they all seem to hit the claimed 90-100MB/s. ProGrade, on the other hand, confirmed write speeds of 130 MB/s. That's just over half the rated 250MB/s speed of their top-of-the-line SD cards, but the price is nearly 70% lower (at the time of writing). So I picked up a couple of 128GB cards. This expanded my range to over 1000 pictures. By purely anecdotal, unscientific observation, the green "Write in Progress" LED stays on longer than when writing to my faster 300MB/s Sony, SanDisk, or Lexar cards. Since the fastest shot I've ever taken was a series of 5 bracketed shots, I rarely had to wait for the buffer to clear. If I choose to shoot bursts, I'm likely to be slowed down more by the 3fps speed than the card's write speed. Okay, so why not just buy a UHS-I 90MB/s card and save even more money? ? Well, UHS-II also offers faster read speeds, so simultaneous image uploads are greatly improved with a read speed of 250MB/s. Also, their additional software and warranty support add value that other brands either don't offer or offer much less than flawless performance.
