128GB Extreme SDXC UHS-I Memory Card - 150MB/s, C10, U3, V30, 4K UHD, SD Card - SDSDXV5-128G-GNCIN

This SD card works great with my Sony A7III and has been completely reliable. I use it for both photos and video, including high resolution stills and 4K recording, and it has handled everything without issues. The speed is excellent. Write and read performance is fast enough to keep up with continuous shooting and video recording without buffering or dropped frames. File transfers to a computer are also quick, which saves time when offloading large files. I have not experienced any corruption or errors. Images and video files have remained intact and consistent, which is critical when using a card for important shoots. Picture quality is exactly as expected with no glitches or data issues. Heat resistance has not been a problem. Even during longer shooting sessions, the card does not overheat or cause performance slowdowns. It fits securely in the camera and has not caused any connection or recognition problems. Overall, this card is easy to use, dependable, and performs exactly as advertised. It has been a solid choice for my camera, and I would confidently buy it again.

I tested this drive with a USB adapter for a PC, and tested with large video files to get an idea of the read/write speeds. The read and write speeds exceeded the specs, working with about 15GB of data. I was reading at about 185 MB/s over 15GB of data read from this drive and written to an NVMe which is a bit faster. Considering this is rated for 150MB/s, that's VERY good. The write speed was also excellent. This disk is rated for about 70MB/s and I got closer to 85MB/s. Once again, writing to this drive, and coming from an NVMe, it was writing at about 85MB/s, and this is rated for 90MB/s. However, the way my system wrote to this drive was almost as if this has about 4GB very fast cache, or it has a small segment of very fast storage, because my system showed that within about 5-6 seconds it had already written about 4GB to it. Then it slowed down and it was showing something like 160 - 180MB/s for a time period, and then the write operation for the PC showed as complete. The USB adapter though was still showing activity, meaning that data was still in the process of getting written, and probably from it's fastest storage to slower storage. The time I calculated for the write time included all the time that the USB adapter was showing activity. If I would have based the write time on when the computer showed the write was completed, the write speed would have been more like 100MB/s I tried to read about these SD cards but couldn't see anything about faster cache or a small amount of fast storage, but that's the way the disk seems to work as far as what the Operating System showed. I know that modern SSDs use that strategy to improve performance, so when you test write operations, you always have to write more data than the size of the cache to see the speed that the main storage runs at. Also, the read/write speeds are listed as "up to", so there is no guarantee that you'll get the speeds that are listed for any period of time. All I know is that working with 15GB of data, this disk performed exceptionally well. Either way, I'm very impressed with it, and as long as it lasts a long time I'll be happy. It was a great price when I bought it and worth every penny.

High quality memory cards. These are my go to. Read and write speeds are perfect for any device. They are very fast. Easy to install in any device. Fit snuggly. SanDisk has always been top tier.

I use these in my Pentax K&F camera, and they work great. They can capture photos as fast as my camera's burst rate and are always ready for my next shot. They are a must-have for any photo project you may have.

Although pricey, this Super fast card is worth it. Loads of memory storage, works perfectly for digital still shot and video cameras, especially for above 1080p to 4k Ultra resolutions. One thing, you must make sure that your device is compatible, this card will either not work or will improperly function if your device cannot handle it's speed and memory. Check your camera specifications first. Also, good idea to transfer and back up these files asap to an external hard drive, because having so much storage on one card could cause a glitch that may cause you to have to format the entire card because of one corrupt file. For the most part, this is a great card, pricey, but worth it. Works perfectly with my 4k Ultra Sony Cam.

Wonderful storage and with all the space I never run out.

Having UHS-II is nice but having more memory cards with lots of space is better than having less cards because like all things, it's not a matter of "if" it will fail but "when"—so load up on lots of SD cards. Don't get too big because if you lose that card, that is a lot to lose. Everyone who buys memory cards should test if it's fake, so if you're on Mac, try Disk Speed Test by Blackmagicdesign. If you're on Windows, I recommend h2testw. 1. Insert your SD card into your computer 2. Run h2testw.exe 3. Select “English” 4. Click “Select target” 5. Select your SD card’s drive letter 6. Ensure “all available space” is selected 7. Click “Write + Verify” 8. Wait until the process is completed The test took about 30min for me. The time varies due to SD card size. If the test finished without errors, your SD card is good and you can delete all .h2w files on your SD card. If the test shows any other results, your SD card may be corrupted or damaged and you may have to return/replace. I bought 4x of SanDisk 128GB when it was $24 for my mirrorless. It's Sandisk—reliable, durable, and best bang for your buck.

It works great! I use it for music recording.

Fits my Canon T7 and says I have 999 photos available. Great disk. Will buy another later for a backup.

I have been having issues with my Spypoint cameras for a while and the SDcards always seem to fail. Since I have tried Sandisk Extreme cards, no issues whatsoever. My cameras stay outside most of the year and these weather proof cards are awesome!

Perfect, work fine with my Sony and Nikon cameras ...
