SanDisk 256GB Extreme microSDXC UHS-I Memory Card with Adapter - Up to 160MB/s, C10, U3, V30, 4K, A2, Micro SD - SDSQXA1-256G-GN6MA

I picked up this 64GB SD card for my Panasonic Lumix DMC-ZS6, and it’s been working flawlessly. Just a heads-up: this camera supports SD, SDHC, and SDXC cards, but it maxes out at 64GB, so don’t go buying one of those huge 256GB cards if you have an old camera. They probably won’t work. 👍 Pros: - Fits perfectly within the camera’s limit and needed the included SD adaptor. - Stores thousands of photos at 12MP resolution. - Can hold hours of 720p video, which is the camera’s top setting. - No setup needed, just plug it in and shoot. 👎 Cons: - Nothing really, exactly what I expected it to do If you’re using an older camera like the ZS6, this card hits the sweet spot. It’s affordable, works great, and gives you way more space than you probably need.

I have 4 of these and have been using them several years now without failure in my dash cams. They're solid.

This microSD card has been perfect for my Raspberry Pi 4. The speed is excellent — everything runs smoothly and responsively. I installed Kali Linux ARM on it and still have more than enough room for the additional tools I plan to add. The price was great for the performance and storage capacity, and the quality is exactly what I expect from SanDisk. It arrived very well protected in the packaging while still being easy to access. Fast, reliable, and high quality — definitely a five-star purchase.

*UPDATE* Your adapter matters far more then you think. I do get advertised speeds when using my Kingston USB 3.2 MobileLite Plus UHS-II card reader. However when using ANYTHING else, the scores are underwhelming...that speaks more to the lack of quality of most USB MicroSD card readers then the MicroSD cards themselves. I got this card originally for my Raspberry Pi, so I didnt go for a 128gb card because its not really needed for a Raspberry Pi certainly not with the projects im using it for. The Pi ran pretty well on it, but as time passed and I looked into benchmarking, I took it out of my Pi, cleared it and benchmarked. I have seen quite a few benchmarks from people running an older version of Crystal Diskmark then me and with a 128GB card that performed as advertised spec-wise...but my benchmark tests were a bit underwhelming, my suspect is the adapter so I will be buying a USB 3.2 adapter and see how that goes, I just hope it works for all cards and not just the cards of the brand who makes the adapter. I tested all of the following methods on 2 different computers both using USB 3.1 Gen 1 SS ports, with a USB 3.1 card reader(Transcend USB 3.1 Gen 1) which has shown in the reviews of it here on amazon to benchmark around the same as my results show, nothing above 95mb/s, so I do believe its bottlenecked at the adapter. I used Crystal DiskMark 7, I also tested using h2testw and doing an actual file transfer. The results are as follows: Crystal Diskmark: BEST results, using peak performance test: 95mb/s sequential read 70mb/s sequential write 7.5mb/s random read 3.42mb/s random write 1838 read IOPS 834 write IOPS AGAIN, this was THE BEST results I got by far with Crystal Diskmark, other tests with the same program didnt do as well, and this is nowhere near the IOPS performance that it should have. This is A1 level IOPS performance. H2testw performance: (writing/verifying entire card) 57.4mb/s write 73.5mb/s read Real life file transfer. Using 6GB folder: Peak write speed: 61mb/s Consistantly around 35-40mb/s Dropped as low as 9mb/s, and CONSISTANTLY dropped as low as 10-20mb/s, and this is a SMALL FILE. I have photos I can upload as verification but this review is not letting me. The Sequential Read speed and Random read/write on MUCH cheaper cards match this 64GB card, the only noticable difference is sequential write is faster on this(SanDisk Extreme) card then others. For comparison I used a 32GB Kingston Canvas Select Plus purchased from MicroCenter (A1/C10/UHS-1/V10 rated) it got VERY SIMILAR benchmarks outside of sequential write which is was significantly slower(17mb/s)...but all random read/write and read speeds were the same. Kingston Canvas Select Plus results CrystalDiskMark results: Sequential read: 95mb/s Sequential write: 17.6mb/s Random Read: 6.62mb/s Random Write: 3.27mb/s Read IOPS: 1615 Write IOPS: 800 Will update when I have a better higher speed working adapter. One concern I do have was in the real world transfer test the speeds dropping significantly, and the h2testw...but maybe that could be the adapter as well? Seems unlikely but I suppose its possible its not able to sustain the speeds. Good card, well see if its great when I get a better adapter.

The SanDisk 128GB Extreme microSDXC UHS-I Memory Card has exceeded my expectations in terms of speed, reliability, and overall performance. Whether you're using it for 4K video recording, gaming, or expanding storage on your smartphone or tablet, this memory card handles it all with ease. With transfer speeds of up to 160MB/s, this card allows for lightning-fast data transfers, making it perfect for shooting and storing high-resolution photos and videos. I’ve been using it with my action camera, and the performance is flawless – no lag, no skipped frames, just smooth and reliable operation. The included adapter is a nice bonus, making it easy to use this microSD card in a variety of devices. The durability of the card is also impressive, as it’s built to withstand harsh conditions like extreme temperatures, water, and shock. Pros: Blazing fast transfer speeds up to 160MB/s Perfect for 4K video recording and high-res photography Reliable and durable in tough conditions Comes with an adapter for added versatility Ample 128GB storage capacity Cons: None so far! This memory card has performed flawlessly for all my needs. Overall, the SanDisk Extreme microSDXC is a fantastic choice for anyone who needs high-speed, high-capacity storage. Whether you're a professional or just need extra space for your media, this card delivers outstanding performance. Highly recommended!

This is one of the fastest traditional MicroSD cards on the market if not THE fastest and performs great at a lot of tasks. I use this in my Asus ROG Ally X(the updated one that doesn't cook MicroSDs) and it is more than enough for emulation up to PS3 as well as older PC games. This is a great way to expand my Ally X's storage without needing an even more expensive SSD than I've already put in it. That it's removable makes it infinitely useful for transferring material from my main PC. I cannot speak for its speed for other uses, however it is the fastest MicroSD card I've ever owned by far. Pretty expensive for the capacity and speed but there is literally almost nothing better for this specific application. Good stuff!

Alles ok!
