Super fast! I have a camera that supports UHS-II and now keeps up with the fastest burst speeds without it having to pause while waiting to write to the card.

I tried another SDXC card (class10) in my camera for 4K video, and it wasn't fast enough. This is one of the fastest cards available and can save the highest quality 4K video with no problems. It is expensive compared to slower cards, but definitely worth it.

Very impressed, I am very aware of the counterfeit memory cards online but i thought I'm protected by PayPal worth giving it a shot. I'm normally a believer of if its too good to be true it usually is. Item arrived quickly and is 100% genuine. I am a photographer using the Sony A7rIII a high speed high resolution camera demanding a lot from the SD card and i have fully tested the speeds of this card and it is living up to expectations. To top this I also ran this past Sandisk and they have confirmed it is a genuine card with full warranty. So if you need a new SD card and want to save 40-50% get them from here, you wont be disappointed.

The card has far more writing speed than I actually need although if the time ever comes that I need to fire off 12 frames per second for an extended time then I know this card will be up to the challenge. Downloading 400 or so files to my laptop is a lot quicker as well and that's compared to the slightly slower 170mb/s cards I used to use. Overall very impressed and I've got the peace of mind as well for future shoots whatever they may be.
Actual memory of 128 GB card is 119 GB. With Sony a7 III It takes 18 minutes to write apr. 2600 uncompressed RAW files (48.3...48.6 MB) to that card which means it writes 2.3 images per second. Manual 3:2 24Mpx uncompressed RAW Silent shooting - ON (8fps shooting) Allows for ~31 images on buffer and ~58 total images in relatively fast speed, then continues at 2.3 images per second. Read on PC with a normal card reader is 150MB/s, but that probably can be improved. In conclusion, it is fast.
I love the writing speed of this card! While shooting wildlife photography you never know when you will need to keep up with a running animal and this card does the trick without staling so I don't miss a move.
we needed a fast chip with a large capacity for bird photography. while this is a pricey item, so was the camera equipment and if you buy a Ferrari you don't put used VW oil in it. this will allow the Equipment to run at full capacity for our needs.
Love using LensRental, efficient, price competitive and quick delivery. Return service always amazing as well!
Because I've never had a SanDisk memory card fail, I purchased an SDXC II for my Canon 90D. Although I mostly shoot photographs, this card's write speed is more than adequ7ate for shooting videos.
SanDisk cards, of any type are the most reliable on the market today. It is very, very rare to have a card fail.
