I bought this to replace an aging 400GB card in a Switch with a lot of games installed. The old card was beginning to slow to less than 1MB/s writes (not sure why, maybe the controller chip was struggling with a lot of bad blocks) and games would actually physically freeze up whenever writing anything (even short little autosaves were terrible!) I spent a day transferring all the data over to this and so far it’s blazing fast — far faster than the old one was even when it was new I think. I’m not sure about 100MB/s as a guarantee, but I was definitely getting a consistent 40MB/s at the very least (I never really tested it fully since reliability is the main factor here, but everything I looked at did at least that, usually more.)So far it seems reliable. I’ve been using it a while and performance is still consistent. No data loss issues or anything either. Only time will truly tell, but at least it’s off to a great start with generally better performance than I expected from a card in the Switch. (I don’t think it can even fully utilize > U1 if even that.)

I bought this to replace a Samsung 256GB that I was using in my Microsoft Surface as extra storage and for games on the Surface. I also use this Surface for a photo booth setup, and having the extra storage gives me a second location to backup photos from the event, should the SSD in the Surface go bad, crash, photos get erased, etc. Bottom line, good price, good deal, happy with it, works just fine.

My last GoPro was very, very picky about the sd cards and took several purchases to get to a happy place. Even some that were on GoPro’s own “ok to use” list would give me grief. This time I checked GoPro and Amazon reviews, this card was favorably viewed.I confirm, this sd card works on my GoPro Hero10 black, without fault, restarts, errors or other difficulty – and it holds a LOT of high res. video.

I just bought another one of these cards after having a good experience with PNY Pro Elite microSDXC cards in my smartphones and just ran two different tests using the latest version of CrystalDiskMark using two different card readers I have.The first card reader is a Kingston MobileLite Plus USB 3.2 microSDHC/SDXC UHS-II Card Reader.The second card reader is a Cable Matters Dual Slot USB C Card Reader (Model Number 201058).I will list the ASIN numbers for each card at the end of my review for easier searching.I cannot be sure if the card readers are limiting the ability of the microSDXC card to reach full advertised speeds or not. All I know is I get slightly different results with the two different card readers while plugged directly into a USB 3.2 Gen2 port on the back of my AsRock X570 Taichi desktop PC motherboard running the latest chipset drivers. Please note that the Kingston card reader has a USB-A type connector while the Cable Matters card reader has a USB-C type connector. However, the USB A and USB C ports that I used on my motherboard were right next to each other and again, both rated for USB 3.2 Gen2 speeds. My motherboard USB ports are rated for that USB protocol. The microSDXC card and the card readers are not. Please see my pics for the test results. The read and write speeds were within +/- 2-3 MB/s of advertised sequential read/write speeds with both card readers. I doubt anyone would notice the difference in real world applications unless you are doing time critical file transfers often. For the average consumer I’d say these cards seem to have a good price to performance ratio, especially when on sale. I can easily recommend these cards to friends and family and I do. Hope this helps you make a better buying decision. A good alternative to these cards to consider that are slightly better in advertised read speeds and potentially around the same price are the Sandisk Extreme brand microSDXC cards with ASIN number B07FCR3316. Those are rated to have a read speed of 160 MB/s with the same write speed of the PNY Pro Elite at 90 MB/s. The pricing seems to be within $5-10 of each other, so not much difference.The Kingston card reader’s ASIN number is B085P5FDXQ.The Cable Matters card reader’s ASIN number is B01KXWIHZY.

Great place to keep my files.
