Samsung MicroSDXC 5 Stars

[This review was collected as part of a promotion.] I do a lot of photography and 3d printing. I purchased the Samsung T7 microSD mainly for 3d printing purposes. The thing that sticks out the most, is the speed this card has. It's the fastest I've ever owned, not to mention the adequate storage space. I purchased a second one for my camera and may get a 3rd for my cell phone. It's warranted for 3 years and protected against water, heat, drops and wear. A must havein my opinion.
I would recommend this to a friend!

[This review was collected as part of a promotion.] I'm currently using my new T7 card in a security camera. I replaced the regular 32GB microSD that only held 12 hours of footage, while this 128 GB card is holding 2 days and still has 100 gigs left. I know, doesn't make sense to me either. So far, I don't really see any difference in playback.
The cool thing is this card can be used in virtually any device that takes microSD, and it's performance would be more noticeable in a game console or phone where apps can be played directly from the card or in high definition video editing. I will be experimenting with these soon!
Another thing to note, these are waterproof and practically indestructible, for those of you who are rough on your microSD cards.

[This review was collected as part of a promotion.] I purchased the T7 128gb micro SD card for a laptop and general memory needs.
So far it's been great.
The packaging now only comes with the card (no reader or storage).
I'm using it in a Samsung Galaxy Pro 4 laptop and used Samsung Magician software to test it and run speed tests.
Everything functioned as advertised and I expect it to continue to perform well for many years based on my low usage and newer tech.
See photos for speed tests and what the item looks like in it's OEM packaging.
I would recommend this to a friend!

Great Micro Card

[This review was collected as part of a promotion.] Samsung T7 128gb micro SDXC - Loving this card so far. I have been using for my digital camera for pictures and videos. It formatted without issue. Transfer speeds are good. I like to transfer my pictures/videos to my laptop for editing and from there to an external storage deivce. Handles large files well, without slowing down during upload. Upload was very fast. Great micro card, already looking to purchase a second one for our underwater camera. I have always purchased Samsung memory cards and this one did not disappoint. Only downside...no adapter or case.
I would recommend this to a friend!

[This review was collected as part of a promotion.] I’ve been using the Samsung T7 128GB microSD card for photos and videos, and it’s been really reliable so far. The setup was quick, and my device recognized it instantly. File transfers feel fast and smooth, even with larger files. I also like having plenty of storage space without worrying about running out quickly. Overall, it’s a solid and dependable microSD card for everyday use.

Does what a good memory card should do!

[This review was collected as part of a promotion.] Slotted it into a GoPro and it was recognized right away. No formatting needed. Pulled the footage off after a shoot and transfers hit close to the rated 170 MB/s with a decent reader.
Didn't stall halfway through like cheaper cards tend to do.
4K records without dropping frames, which is really all you want from a card in an action cam. The V30 rating holds up under sustained writes. A2 doesn't matter as much in a GoPro but nice to have if you ever swap it into something else.
The card itself feels solid. Not flimsy like some no-name ones where you worry about the contacts. Samsung lists it as waterproof, X-ray proof, and magnet proof, which I have no plans to test but nice to know it's built for being tossed in a bag with the rest of the gear.
I would recommend this to a friend!
