    Perfect for Nintendo Switch Storage Expansion!
    Absolutely love this microSDXC card! I used it in my Nintendo Switch, and it works flawlessly. The read and write speeds are impressive—games load quickly, and transfers are smooth. Installation was simple, and the included adapter is a nice bonus if I ever need it for other devices. This card has been a reliable way to expand my Switch storage without any issues, and I’d highly recommend it to anyone looking for a fast, dependable, and affordable memory solution.

    This IS really faster than other memory cards I’ve tried! It’s a problem solver!
    Dont let the size fool you. This sdxc card really packs a punch – I usually use these in my time lapse cameras but this one is different as it actually works – what I mean is other cards seem to misbehave in my cameras and dont get the files written to them properly wich causes me to have to do a few extra steps to get the files functional – so I used the card in a time lapse camera that I was having trouble with and guess what? This one performs like it should have – no issues, no problems – files were all fine and perfect and I didn’t have to change anything! size and fit are perfect – this will be my goto Micro SDXC card from now on!

    Great except Amazon owes me 50 gb
    Got it for my Steam Deck. No issues at all, works perfectly so far but will update if anything changes. I do take a star away due to it not having a full terabyte of space. I know that every single sd card, flash drive, and ssd never has the full capacity regardless of brand. I was short about 50gb which is significant. Read and wrote speeds are lightning fast. Performs as well as any name brand. Just know you’re only getting apx. 95% of the storage that you paid for.

    Great Buy
    I recently bought the Amazon Basics 256GB microSDXC Card with Adapter, and it’s been an excellent purchase for the price. The card works perfectly with my phone and action camera, delivering fast read speeds close to the advertised 200MB/s—great for 4K video and large file transfers. The included adapter is a nice bonus and makes it easy to use with my laptop.

    Great for GoPro users.
    I will be getting more of these. They are recommended by GoPro to use. Huge storage capacity for the price of others. Performance is very good. No drop in video quality. I use for my hero 12 + 8. Plus works very well with my hero4k. I’ll load up on these when I place an order. They last all day when I motovlog and record.

    Parfait petite taille, fonctionne parfaitement sur mon s25 ultra avec une carte micro 256ga. Vitesse correcte de transfert dans les 2 sens.J ai ajouté un film de 24go sur la carte pour lire sur mon tel et ça fonctionne parfaitement. Testé. Des transfert du pc vers la carte et idem du tel avec cet adaptateur et c est c est vraiment génial. La partie usb est de qualité et pas besoin de forcer pour la mettre sur le tel. J ai pu lire sur autres articles du MM. Type que certains pouvaient endommagee la prise usb. Ici ce n est pas le cas.Je recommande fortement J en suis très satisfait

    This is a fairly (and surprisingly) decent Micro SD/uSD card reader from Amazon Basics that’s reasonably well-made and for the most part works as expected without issues. It’s reasonably small and compact although far from the slimmest that I’ve come across and tested due to its odd and slanted shape that’s just weird. It has a typical plastic shell that’s certainly not something to write home about; however, it does have a spring-loaded card slot, which is a surprise to me (and indeed a pleasant one at that).As for its dimension, it’s about 25 mm in length at the shortest side and 29 mm at the longest. As for width, it’s about 18 mm at the shortest and 23 mm at the widest. Finally, the thickness is about 11 mm; however, the slanted side has a length of 12 mm measured at the surface.As far as data transmission is concerned, it’s able to provide the [nearly] max speed supported by the various Micro SD cards that I’ve tested and the best result is about 175.25 MB/s for read and 155.85 MB/s for write, which is again fairly good. This particular card reader also supports OTG that many others don’t, so that’s certainly a point in its favor.Before purchasing this, I tried about half a dozen UHS-I card readers from various well-known brands including Kingston, UGREEN, and TP-Link etc. just to name a few. However, most of them weren’t able to achieve speeds faster than 104 MB/s (which is the max speed for UHS-I), and for the few that could go beyond 104 MB/s, they were capped at roughly 150 MB/s, which was weird.The max speed for UHS-I is 104 MB/s and that limit is increased to 156 MB/s (full-duplex) or 312 MB/s (half-duplex) for UHS-II; however that requires the use of an additional row of connectors on the cards as well as the card readers that relatively few have adopted even today.★ In the meantime, proprietary technologies have been developed by SanDisk and others to bump up the existing 104 MB/s limit to something much higher, including DDR200 (170 MB/s) and DDR225 (200 MB/s) and so on. This is the ONLY card reader that I’ve tested in the last month that’s actually able to achieve 175.25 MB/s (max 180 MB/s for the card in question) via UHS-I interface.Kingston used to have one that actually worked (from about 3+ yrs) but that’s no longer the case with the new version that’s available at the moment, so if you need a UHS-I card reader that actually works to go beyond 104 MB/s at the moment, this is THE card to get.≡ ValueAll things considered, this is a fairly decent uSD/Micro SD card reader that’s fairly small/compact and works as expected without issues. It’s the ONLY UHS-I card reader (out of the half a dozen or so cards tried) that’s able to go beyond 104 MB/s (max 200 MB/s claimed) imposed by the standard. I just wish that it has a slimmer and rectangular shell instead of one that’s oval and slanted at the rear, which is just odd and weird. It’s reasonably priced at $10 for what it provides and its overall build quality, features (i.e. DDR225, 200 MB/s), usability, versatility, and performance.
