128GB Extreme microSDXC UHS-I Memory Card with Adapter - Up to 160MB/s, C10, U3, V30, 4K, A2, Micro SD - SDSQXA1-128G-GN6MA

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.

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.

Got the 512 GB model to expand on the Steam Deck's admittedly limited storage. Even if you got the largest storage model of the Deck (512 GB) it can fill up quickly. Games are just bigger nowadays. I think the newest Call of Duty is like 150 gigs. Just like every storage manufacturer, they advertise the storage in "GB" instead of "GiB", so when you actually plug it into a computer you lose some space in the conversion. In this case, after you format it on the Steam Deck (ext4 I believe) you end up with 468.2 GB of usable space. Which admittedly is a tiny bit bigger than the Deck's own 465.3 GB of usable space on the 512 model. It seems like every storage mfr. has their own way of making this GB/GiB calculation, and it's just plain annoying how they always favor giving you less storage than it says on the label. It's so common now it's pretty much standard practice with them, so what can you do. But losing 9% of your storage space is never fun, so it's always worth complaining about again. The largest game I have loaded on this card is Horizon Zero Dawn Complete Edition, which is 73.48 GB. And the stories are true, it loads pretty much just as fast as the Steam Deck's own SSD. The game's intro comes with a few somewhat lengthy cutscenes, and game developers have gotten pretty good at hiding the loading screens in the background now, but still there was absolutely no wait at all between gameplay sections. In fact, I have another older game "Destroy All Humans!" (2005) on the Deck's SSD that has more hard loading screens, and it just "feels" like it takes longer to launch and load new levels than Horizon Zero Dawn on the micro SD card. HZD had a few times where it would stutter during the intro cutscenes, and drop to 20 FPS very momentarily, but for some reason this seemed to clear up after about 30 mins in, and otherwise ran at around 35-45 FPS. Definitely watchable. Gameplay was much smoother, had absolutely no stutters, and ran really consistently at around 40 FPS. Definitely playable. And not all of that may be down to the card. I'm not sure if Horizon Zero Dawn uses pre-rendered cutscenes or not (basically a video file), but it might explain the odd stuttering that only happened during cutscenes, and not during gameplay. However you would think streaming even a 4k video file should be easy, stutter-less task for this card. Another reason could be Steam's own weird download behavior: if you want to download multiple games at the same time to load your new card up, each time you click "Install" on a new game, Steam will interrupt whatever download it was currently working on and immediately start downloading the game you just clicked on, putting whatever it was downloading before into a queue. As far as I know, there's no way to just add games directly to the queue, to have them each download 1-at-a-time uninterrupted. If there is that option I haven't found it yet. (You would think this would be the default behavior anyway.) This means when I clicked on 8 different games to start downloading at the same time, each time I clicked on the next one it would pause the current download at around 1% complete, and only pick it back up again once the last one I clicked on completed. This causes pretty bad fragmentation in your game data, with the first 1% of 8 different games stored at the beginning of the card. But it could explain the rare stuttering in the intro cutscenes that somehow miraculously cleared up after a little while. Solid-state storage is supposed to have much better random IOPS read performance than HDDs, but no matter what when you've got fragmented data you're going to get slower speeds than continuous reads. FYI, you can transfer games between 2 different micro SD cards directly on the Deck. I was using a temporary 64 GB card while waiting until this one arrived, and my Windows computer couldn't read the ext4 or whatever filesystem Deck uses, and I didn't want to mess around with new drivers to get that to work. But with a few USB-C to USB-A adapters and micro SD card reader, it's easy to do on the Deck itself. It won't show up on the Deck's Storage menu of the main interface, so you have to hold the power button down and switch to Desktop mode, where you can use the standard file browser to copy things over. Keep this in mind before you start troubleshooting your wonky series of daisy-chained adapters/card readers because you think they aren't working. And make sure you format the new card first. Another FYI: I had a little scare thinking I bricked my Deck or something when I first installed this card. I made sure to completely shut down the Deck before swapping SD cards, but I think that confused the bootloader. When I turned it back on the Deck had a completely blank, black screen, and Steam didn't load. It turned out the boot order somehow got switched, and it was trying to find the Steam OS on the new microSD card instead of the Deck's SSD. To fix this is easy, while it's off hold 'Volume Down' and click the Power Button - when you hear the chime, let go of the Volume Down button, and you'll be booted into the Boot Manager. There you can fix the boot order, and I haven't had it happen again since. Just search "steam deck recovery" online for more info, Valve has great instructions.

Bought this for additional game storage on my Steam Deck. Works as expected. No issues. Good value for the amount of storage.

In short this is a great card and it's speed falls close to it's advertised speeds. ADVERTISED ACTUAL READ: 160 MB/s 149 MB/s (93.13% of advertised speed) WRITE: 90 MB/s 109 MB/s (121.11% of advertised speed) The results above are from the SanDisk Extreme 128 GB card, SDSQXA1-128G-GN6MA bought in Q1 of 2021. Unfortunately, there are MANY fake SanDisk cards on the market everywhere and they can be very problematic if bought and used. I highly suggest you test ANY sd card that you buy. In general, I always want to get at least 90% of claimed speeds. Different hardware or software optimizations can make it to where you may not get speeds as high as claimed, but if you are close to them, close is good enough. Only read on if you are researching SD cards and verification or are just a nerdy person like myself. When looking up SD cards it's important to keep a few things in mind: * Investigate the claims for speed if it is important to you. The card may say xxx MB/s write speed* That asterisk may reference that the speed is only guaranteed when using a certain software. Since you might be like me and installing the card into a phone, that phone will most likely not use that software so the speeds will be lower. For a more real-world speed, look at reviews who have verified the speeds either in the device that you plan to use it in, or by other software to benchmark it. * Always test the speed of the card once you get it (The speeds above come from a program known as H2testw) * Always test the storage capacity of the card. * I highly recommend that you test your card using H2testw. It tests the two most important things about your storage: actual speeds, and actual storage. Fake or faulty cards cannot hit their advertised speeds. Fake cards often are edited to report a false storage to your computer. Say you buy a 128GB card and you read the size in Windows, 119 GB. Seems close enough right? Well this is not a guarantee of the real storage capacity. The card could be a 4 GB card that is written to report itself as 119 GB. For the first 4 GB of space or so there will be no issues with the card, aside from likely slow speeds, since fake cards often use slower, cheaper memory. After writing these 4 gigabytes however, you will inevitably have data corruption. The original 4 GB stored on the card will start to be overwritten by the next data to come. This can result in a total loss of date. This is the big danger with fake cards. It's one thing to have a slow card, but another thing entirely to lose your data. You could lose valuable data and there are times when this data cannot be recovered. * Know that your storage space will always be less than advertised. In my case, my 128 GB card has an actual storage space of 119 GB. This is in mainly due to the fact that the advertised capacity is often the unformatted, "RAW" size in decimal (base 10) storage. However, your computer reads storage in binary (base 2) storage. In this case, if we take 128 GB of decimal gigabytes and convert it to binary gigabytes, we get 119.21 binary gigabytes. When your card is formatted, it is formatted using base 2 since your computer understands binary. Decimal is essentially only used for advertising as far as us typical consumers are concerned. H2testw will test the true capacity by filling the entire card with however much information it can put into it, then reading it back and verifying that the information stored is correct. A fake card may be 4GB and allow 119GB to be written to it, but when the information is checked, there will be discontinuities in the data and the fake card will be exposed as such. Good luck finding a card that works for you.

Item arrived as promised and packaged securely and nicely. Works very well.
