Extremely Fast and Reliable for High-End Recording
Style: Card Only Capacity: 128GB
This SanDisk Extreme PRO SD card delivers excellent performance, especially for high-resolution video and fast shooting. The speed is the standout feature. It handles 4K and even 8K recording smoothly without dropped frames, and file transfers are noticeably faster compared to standard SD cards. It’s a great choice for cameras that require high write speeds, especially for burst photography or professional video work. Build quality feels solid and dependable, which is important when you’re trusting it with important photos and footage. It performs consistently without errors or lag. The 128GB capacity is also a good balance — enough space for large projects without constantly needing to swap cards. One thing to keep in mind is that to fully benefit from the UHS-II speeds, your camera and card reader need to support it. Otherwise, it will still work but won’t reach its full potential. Overall, this is a high-performance, reliable SD card that’s well worth it for anyone serious about photography or video. Easy 5 stars. ... show more

This efficiency has significantly improved my workflow, allowing me to capture and store more images without the usual delays I’ve encountered with other cards.

Must have UHS-II device or adapter for full performance
Style: Card Only Capacity: 128GB
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/B09T63PQ1W With 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 ... show more

Good Product - Shipping Concern

This memory card is perfect. Price on Amazon is comparable to Best Buy. The problem is with the shipping. Luckily I asked to have the product shipped in an Amazon box. Received a mangled exterior box, barely intact and luckily, the product and product box was not not damaged.

Reliable Storage for 4K Use, Just Not the Fastest Transfers
Style: Card Only Capacity: 128GB
Review Image by Rigoberto Gaetan
I purchased this SanDisk 128GB Extreme microSD card in 2020 and it’s still working perfectly. I’ve used it mainly for recording video and storing media, including 4K footage, and it has been very reliable. I’ve never had any crashes, corrupted files, or issues with devices recognizing the card, which is a big plus. Transfer speeds to a computer aren’t the fastest compared to higher-end cards, but for the price, the performance is fair and consistent. For recording video and everyday use, it does the job without problems. The included adapter is also convenient when moving files between devices. Pros: Very reliable, still working after years Handles 4K recording without issues Good value for the price No crashes or corrupted files Adapter included Cons: Transfer speeds are not the fastest Not ideal if you move large files very frequently Conclusion: This SanDisk 128GB Extreme card is a solid and dependable option if you want reliable storage at a good price. It’s not the fastest for file transfers, but for recording, everyday use, and peace of mind, it’s a great value. ... show more
