A Petition for Fujifilm, and Sandisk


Recommended Posts

And Sony's latest debacle.

The only photography channel I trust, has never lied about recommendations, or camera lenses and other camera accessories; Proclaims that Sandisk is the only card that people should use.  However, they are sticking to the slow, and useless V30, (useless) instead of making a V90 SDXC card for the XT-4.  Not saying it is a bad card, or bad card company, just not good enough for 4K with 400mbps video that the XT-4 can produce.

The petition is this:  Work with Sandisk so they can give full quality SDXC cards for video use.  By that I mean V90 Sandisk SDXC cards.  People are paying big money for the junk V90 SDXC cards.  With the amount of money they are paying for the XT-4, they should get the full quality.  Not half the quality they pay for.

I use Lexar since the launch of X-T1 in 2014. I also use other UHS-II cards : Fujifilm, Sandisk, Sony  and Toshiba. I never had any issue with all these brands.

Thanks, good to have as many points of view as possible.

I'd suggest doing your research before complaining about this. The V speed rating is relatively new and Sandisk has not refreshed their UHS-II offerings since the V spec was released.

Sandisk's V30 cards are their latest UHS-I cards, and that is the highest rating that can be applied to UHS-1 cards. These are actually capable of almost V90 performance (measured sustained sequential writes of over 85MB/s) and would have been rated as V60 cards if that rating was available for UHS-1 cards (which are artificially limited to V30 as a max rating despite the top UHS-1 cards delivering performance that essentially matches the V90 requirements)

Sandisk's UHS-II cards all qualify for the highest speed ratings available at the time of their introduction. However testing on sequential write shows sustained write performance of over 240MB/s, some two and a half times better than a V90 spec would require.

Note if you compare performance, only one V90 rated card has faster sustained write performance than the Sandisk Extreme Pro UHS-II cards, and it's the Sony Tough card that's middle of the pack in terms of the top performers (most of which are not V90 rated). The fastest sustained write cards on the market are not V90 rated because the spec is too new)

So, in summary a quick check of actual performance would show you that Sandisk's top performance UHS-II cards had exceeded V90 spec before that spec existed. You should be using UHS-II cards for maximum performance in a X-T4 body.
