Works great with my camera! Beautiful photos and videos

My application is photography, specifically with an OM-5 camera. The cards are used to move batches of images between the camera and computers, or as a temporary backup. I'm mainly interested in out-of-camera speeds. I'm not too concerned with shooting at the maximum burst rate, which could be affected by SD card choice.Does it work as advertised? Yes. Would I buy it again in the same circumstances? No. I would buy the SanDisk Extreme Pro 200 MB/s card for $21 rather than this one at the Prime Day price of $85, and certainly at the after-sale price of $110.I did quite a few tests copying the same directory of RAW and JPEG files between various devices. There were 1,758 files in 37 folders. There were also a few small video files, but mostly 7 to 9 MB JPEGs and 17 to 28 MB RAW files. As a reference point, I copied from a SanDisk external SSD to my desktop's internal SSD, getting 780 MB/s. This simply shows that the USB-C port and the internal SSD would not be limiting factors. The USB 3.0 ports I used should also be more than adequate, rated at 625 MB/s or higher.Below I will omit the differences between my computer's USB-C and USB 3.0 ports, which I tested both at the front panel and using the backside mother-board mounted ports. This differences were small.Back to the title - I mentioned adapters. To use the speed of this new card effectively, I had to get a UHS-II compatible adapter. It was the JJC device here on Amazon of $18.99: https://www.amazon.com/dp/B09T63PQ1WWith this and the new card I got read speeds of 224 to 238 MB/s and write speeds of 79 to 87 MB/s. The read speed was around 78% of advertised, which is not bad for so many separate files. Write speed was only 31% of advertised, rather disappointing.Do you need the special adapter? Yes, if speed is important. With an Anker adapter which supports UHS-I I got read speeds around 76 MB/s with this card, much less than the 230 or so with UHS-II. Write speeds were about 45 MB/s, not much over half of the UHS-II speed.Why would I buy the slower UHS-I SanDisk card (https://www.amazon.com/SanDisk-128GB-Extreme-UHS-I-Memory/dp/B09X7FXHVJ/)? It is a $20 card and I got write speeds 74 MB/s with the JJC adapter and 55 MB/s with the Anker adapter. With the JJC adapter the UHS-II card was only slightly faster, and with the Anker adapter it was significantly slower.Read speeds went like this. The UHS-I card gave 154 MB/s compared to 230 for the UHS-II card, which is a nice advantage for the subject of this review. To me it is not worth more than 5 times the price for 1.5 times the speed. That was with the faster UHS-II adapter. With the Anker adapter read speeds were practically identical and write speeds were actually better with the Anker.I did test with one other card, an older 45 MB/s card. I gave over 90% of advertised speed with reading, better than the newer cards. Writing was 50 to 54% of advertised. Adapter type did not matter much. These are now down to $12.18, but I'd probably stick with the 200 MB/s cards

Love this brand and this product, specifically. As a professional photographer, I use these items almost exclusively to capture and store my most valuable assets for clients and projects. I have found them to be reliable, durable, and great value for the money. I have bought dozens and will continue to do so for as long as the quality remains the same and the price is good!

I got this card months back and it was a faulty card, fresh out of the box! I did however buy another one and it work out fine and sent the nonfunctional one back. Works great so far!

Good high speed sd card. Not a ton to say.
