Wow.
80MB write.
Only 10MB less than what Sandisk had 1.5 years ago.
I come here for the whining
Indeed, but compare the prices…the Kingston has more bang for your buck 🙂
That’s because it takes multiple attempts to actually write.
Kingston has horrible reliability.
Kingston has horrible reliability? Maybe you work for Sandisk 🙂 Or wait, it’s extreme fanboyism or pure trollism.
P.S. I’ve used a lot of Sandisk and Kingston producs and the reliability is the same. Sandisk has an advantage in speed but that advantage is overpriced (like 1.5 or 2 times the price for the omologue product)
Sandisk Extreme Pro 32GB is $60 on Amazon, vs $54 for the Kingston. Sandisk lists 95R/90W, vs 90R/80W for the Kingston, but its U1 vs U3 in Kingston, so minimally guaranteed speed might be better in the Kingston (the listed are some peak speeds rarely achievable in practice).
I don’t work for SanDisk.
I’ve seen Kingston play a game where they present a reasonable product. Then, they present the cheaper successor with unreliable control chips or lack of proper shielding, and then, it malfunctions repeatedly.
Kingston isn’t as bad as Adata–they don’t consistently make faulty products but I find them better to avoid. SanDisk and Lexar don’t play games, as far as I’ve experienced. If the price is a bit higher (and it usually is), I buy fewer and wait for a promotion.
My kingston cards lasted longer than my sandisk cards. However, the sandisk was blazin fast while it worked.
These UHS-I class 3 cards are not bringing anything new to the table as these cards only need to support 30mb/s. Sandisk has been supporting 90mb/s writes for a while now. This is just are marketing standard for 4k video support.
What is of more interest is the new UHS-II cards that support up to 260mb/s writes. Fujifilm’s X-T1 support this new standard and we need more manufacturers to jump on. If the GH4 has supported UHS-II then it would likely be able to write 10-bit 4:2:2 to the card directly instead of requiring an external recorder.
UHS 2 cards write less than 30Mbs during video recording. If you try to stick a UHS 2 card with a 4K recording device the footage will look choppy. You have to use a UHS 3 card to record 4K.
The 90MB/s on the older SanDisk cards is a maximum PEAK speed, not a minimum CONTINUOUS speed. Who cares how fast a card can go for a second or two, for video you need a reliable constant speed.
The testing I did on my Sandisk shows a consistent 90mb/s write. 3x the requirement of 4k video
But Kingston is a big sh1_t brand
Good luck if you want to trust your best life moments to this piece of crap
Kingston, Sandisk and Lexar are the most reliable card on the market. Period.
What is a GH4?
I thought its name was G4K..?? to the cards, I have tested Transcend and Kingston, both are crap. I had serious problems with them. Sandisk is the one and only as it seems..
with this super FHD, we need to have new pc hardware to edit it comfortably I guess right?
Should drop all this card crap and just have a micro SATA3 1.8″ SSD… job done.
I really do have to wonder what makes this particular introduction of a card noteworthy as its own story (as opposed to an advertisement).
Hi all!
I read that Sandisk extreme pro sdhc/sdxc new UHS II will also do 280mb/s… But I was kind of shocked that the speed was for continuous burst mode shooting and transfer speed when copying files, only 30mb/s for continuous shooting video..

Proberly the same for the Kingston card…
Thats proberly why the gh4 will not be able to record 4:2:2 1080p internally? Pls someone comment me thnx!
