KingstonCanvas React Plus 256GB SDXC Memory Card UHS-II 300R/260W U3 V90 for Full HD/4K/8K - SDR2/256GB

The media could not be loaded.  I've been using Lexar 2000x V90 cards for professional photography work with high end Sony mirrorless cameras the past couple of years. I always felt they were a bit slow to clear the buffer but thought this was just the limit of technology, and needed CFexpress Type A cards to see more speed.In researching some reviews of "best SD cards for Sony A1", I came across a group test that highlighted the underperforming Lexar 2000x cards, with a write speed half of that advertised. These Kingston SD cards came out on top of the group test so I gave them a go.It is a huge difference when clearing the buffer during high fps bursts - see the video comparing a short burst using both Lexar and Kingston cards. The current price is unrivalled vs other top tier SD cards - I'm struggling to find fault with them and am about to order a bunch more to replace all my Lexar cards.Since I've only just received them I can't comment on their longevity but will update this review when appropriate.

What l like :Kingston is well known make but cheaper than SanDisk or Sony. Works well with canon r10 at 13 frames per second canon c raw with no buffering

A quick and non-very-technical review here.I have used this in a Sony a7riv and it doesn’t seem much faster or slower than Sony’s v60 M series which is 277/150 and similarly priced. I assume Sony’s V90 would be much faster, so this is just ok for the price.

Cheapest of the big brand UHS-II, as fast as the best, historically very good brand (can't comment on longevity as my card works!) ... Really no point buying any other brand, get this one.

Got some of these after upgrading to the Sony A7IVThese allow me to outrun the buffer while my older cards would slow down quick

I independently researched new SD cards for my new camera and this card by Kingston came out best, whilst others were surprisingly disappointing. Sor far it works very well.

A fast card for writing in camera. Clears buffer quickly, even with RAW.

I recently got two of the Kingston 128GB V90 UHS-II cards to use on my A7SIII. I was able to shoot in all the 4K formats, including the whopping XAVC S-I 4K 60p 4:2:2 10-bit 600mbs, since this card is rated V90 so it will sustain an extended write rate of 90MB/s (fyi 600mb/s = 75MB/s) though do bear in mind 128GB will only give you 28 minutes at that data rate because the files are so enormous..
