SanDisk 64GB Extreme microSDXC UHS-I Memory Card with Adapter - Up to 160MB/s, C10, U3, V30, 4K, A2, Micro SD - SDSQXA2-064G-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.

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!

*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.

I haven't had good luck with Sandisk micro SD cards. I haven't had any failures but these are my two issues: 1. On large file transfers - more than 1gb - Sandisk tends to overheat and lose transfer speed. This is worse writing TO the card than reading from it. Transfer speeds are stil ok, but nothing like the speeds I get from my USB 3.1 port with a thumbdrive. Several years ago the problem was so severe my files got corrupted even when the on-board thermal protection was throttling my transfer speeds down to 5-10 megabytes per second. In the past two years data loss has ceased to be a problem, and the speed hit on large file transfers is much less severe, although Samsung continues to run faster, in real life big file transfers, than San Disk, at least for me. 2. I don't think Sandisk really meets the specs required for "extendable" or "unified" storage on Android, that or it throttles so early the perfomance on small, constant file reads and writes suffers more than it should. I almost always get an error message with their A1 cards on budget (Qualcom 42x chipset) phones complaining the storage is slow and hence not optimal as unified storage. I haven't gotten this error message with my two Fire HD 10 9th gen tablets on this latest A2 iteration, however, which may be a function of the chipsets and memory controller used in these tablets or maybe the upgrade from A1 to A2 makes a difference. I purchased two Fire HD 10's, 2020 editions/9th gen (the second one purchased on Prime Day for just $80, which is insanely cheap) and two of these A2 class Sandisk 128gb micro SD cards. A2 means the memory controller built into the micro SD card should be fast enough to run apps (not gaming apps!) from the card, not just read storage data. The real challenge is for app-rated (A1 or A2) card to handle data reads and writes for multiple apps at the same time. "Same time" is critical - it's not reading a single big file that creates problems for micro SD cards, it's reading small files at nearly the same time to handle the needs of multiple apps running at the same time. The way to avoid any performance issues is to NOT allow the operating system to "move" apps from true internal storage to the SD card. Only data. The first 128gb drive installed perfectly easily in my first Fire as "portable" or "removable" storage but that is not surprising. The second card was installed as "internal storage" in the second Fire glitched several times, crashing once, and not recognized by the tablet as storage at all. I don't know what I finally did to get past the glitches. but as far as I can tell what finally worked was first formatting it as "portable" storage first, rthen ebooting, then re-formatting it as "internal" storage. I was "offered" a chance to move some apps onto the SD card after formatting as internal storage. DO NOT do this - the 32gb of internal, faster storage is a much better place to run apps from, not the SD card even though it is A2 "app-friendly" classified. All CONTENT will automatically go to the SD card in the future, such as downloaded Netflix and Prime Videos. Pay attention to the following issues which might develop: 1. Simultaneously downloading videos or other content AND watching a previously stored video. This can tax the memory controller in the SD card since essentially the device is attempting to read your video and write your downloading episodes at the same time (subject to buffering). It shouldn't be a problem,but it might. I usually download content when I'm not using the tablet. 2. Moving lots of content from external storage - like a thumb drive - to internal storage. The process is ALWAYS a lot faster going from USB 3 thumbdrives to internal factory storage, and slower when writing to the SD card. In my review title I mentioned I prefer Samsung. Without doubt they make more dependable SD cards that more consistently "hit" their specs and don't throttle down as much on large file transfers. However, Sandisk pretty much "owns" the A1 and A2 "app friendly" micro SD space, and they frequently go on sale. Since they no longer "corrupt" large file transfers (I'm talking about moving a 30gb music collection to an SD card in a computer, not just a couple of gb), I no longer avoid Sandisk like the plague. Still, as they say, once burned twice wary. I'm hunting for reviews from Raspberry Pi users. Running an actual operating system from a micro SD card is equally hard, or harder, than running Android apps. So far, the micro SD cards recommend for those Raspberry Pi systems are NOT A1 or A2 class or even necessarily "faster" micro SD cards - apparently speed on larger files doesn't necessarily correlate to the speed required for smaller, constant file transfers that an operating system needs. It's good to see micro SD card prices become so low and commodity-like. I can remember when cards were a dollar a gigabyte, or much more. For under $20 I'm more than willing to give this Sandisk A2 128gb micro SD card a workout in my Fire HD 10 9th gen. I'm also a little surprised to see all the new brand names. I'm used more to Samsung and Sandisk at the top, with Kensington, Patriot, etc. as the next tier. My guess is Chinese subcontractor factories feel less bound to have a long-standing brand name and are just going direct to market. Time will tell how this works out for consumers.
