Amazon Basics microSDXC Memory Card with Full Size Adapter, A2, U3, Read Speed up to 100 MB/s, 256GB, Black

“Reliable memory cards with fast transfer speeds and plenty of storage space. Worked perfectly for my devices without any issues. Great value for the price and useful for photos, videos, and extra storage.”

Excellent value for a 256GB microSD card — I honestly was not expecting this level of performance at this price point. The Amazon Basics branding had me a little skeptical at first, but after putting it through its paces, I am genuinely impressed. Speed & Performance: The card delivers on its A2 and U3 ratings. Read speeds are consistently near the advertised 100 MB/s, which makes file transfers fast and smooth. I use it in my dashcam and security camera and have experienced zero dropped frames or buffering issues. The A2 application performance rating also means it handles app loading and random read/write tasks reliably. Storage & Reliability: 256GB is plenty of space for extended video recording, photos, and app storage. I have been using it daily for several months with no data loss, corruption, or errors. It gets warm but never hot, even during continuous 4K recording sessions. Compatibility: It comes with a full-size SD adapter which is a nice touch — useful for transferring files to a laptop or camera. Compatible with a wide range of devices including smartphones, tablets, dashcams, drones, and action cameras. Value for Money: This is where the card truly shines. Compared to branded alternatives like SanDisk or Samsung at the same capacity, this card offers comparable real-world performance at a significantly lower price. For everyday use cases like dashcams, security cameras, or extra phone storage, there is simply no need to pay a premium. Highly recommend this card for anyone looking for a reliable, fast, and affordable storage solution.

I’ve been using this 256GB Amazon Basics Micro SDXC Memory Card for a few weeks now mainly in my action camera and tablet, and it performs exactly how a good microSD card should — stable and fast. The read/write speeds are solid. File transfers to my computer are pretty quick, and it records Full HD and 4K video smoothly without lag or dropped frames. Apps also load faster compared to my old card, probably because of the A2 rating.

It’s also reassuring that it’s waterproof, shockproof, and temperature resistant since I use it outdoors a lot.

I have cameras around my property, I have the option to use cloud storage from the camera maker, adding a DVR/HD, or install an sd card on each respective camera. I found that there's always the potential that someone, if they are truly intent on doing it, will take the cameras, and if they make entry into my home or business, they'll steal anything of value, and a DVR/HDD/NVR almost always will be taken if found. I keep most of my cameras (which are all webcam), most are bullet style, but I do have several PTZ, they are all wireless, but obviously have a power supply connected, and I have since started to only purchase solar powered, but have had marginal success with them, as those style of cameras are limited by where you put them (full-sun light versus limited limited line of sight with the sun). Ultimately, I prefer the sd cards, they are easy to install, are remarkably cheap, and to date, I have NOT had any fail prematurely (usually the camera, or it's power source/supply does well before any issues are observed by the sd card. Originally I thought I had an issue with the sd cards not provisioning/formatting, but then realized each camera's maker has expectations on how the format occurs. The number, and compatibility I have with this brand of SD card, and the overall life span leaves me a happy customer, and ensures I will continue to purchase these in the future.

I bought this for my Vivitar movie camera. The memory card worked great. The Vivitar camera was unworkable and I threw it away. I kept the memory card, although I'm not sure what I'll ever do with it now.

Ok

Une bonne carte micro SD avec un adaptateur. Il m'a servi pour augmenter la mémoire de ma switch. Elle a tout de suite été reconnue et j'ai pu télécharger mes jeux dessus. Les 256GB sont suffisants pour l'usage que j'en ai. Vraiment très satisfaite du produit. Je recommande cette carte.

Hasta ahora funciona muy bien, se utiliza en una cámara digital.

Been using it for 2 months now, have not faced any issue, looks good, nice quality, have not faced any data loss, supports most android phones that can support high memory.

Perfect for my TAPO security cameras
