SANDISK MobileMate USB 3.0 microSD Card Reader - SDDR-B531-GN6NN

This microSD card reader does exactly what it’s supposed to do. It's compact, easy to carry, and worked right away when I plugged it into my computer. I used it to transfer photos and videos from a microSD card, and the transfer speeds were quick with no issues. I also like how small it is because it doesn't take up much space in a laptop bag or camera case. The card fits securely, and I've had no problems with connectivity or reading files. Overall, this is a simple, reliable card reader that gets the job done and is a handy accessory to keep around if you regularly use microSD cards.

Problem: PCs these days don't usually have MicroSD readers and I needed one because I own phones and tablets. When I want to transfer gigs of pictures/videos to my PC this card reader does that easily and quickly. Speed: I bought this because its USB 3.0 which means I should get 500MB/s. When used with a C10 or U1 MicroSD that only does 100MB/s the card itself is the bottleneck. Even a U3 is 300MB/s peak transfer and a high quality V## MicroSD are the exact same UHS2 300MB/s speeds and means this device is somewhat futureproof for a while. Capacity: ZERO! On the user. I bought a 256GB U3 MicroSD card for less than 20$ to leave in it. Intended use vs actual use: Wanted it so I could transfer files easily but that's not that often. Practical use, I installed CallOfDuty and its 200+GB on the card and run my game off the chip now. I feel like it loads MW3 faster and is a bit smoother. Less than 30$ I kinda unintentionally got a setup that helped my gaming by freeing up space and improving my performance while still allowing me to transfer files from portable devices when I need to. Perfect for what it does and I'd buy another one if I ever need to. Parts are durable and its compact so I doubt it will break since there's nothing really to break. It's nice solid hardware and a great value for the price.

Read and write speeds are fast and super reliable, I’m thinking of buying another one for my other computer.

For some bizarre reason, it does not fit into the USB-A slot in the back of my Marantz M1 streaming amplifier. A different SD & micro SD reader that I own works fine in that slot, so I know it’s not a problem with the amp. I wanted a lower profile reader that wouldn’t stick out so far like the one I already had, which has both, USB-C and USB-A connectors on both ends, and reads both, SD and MicroSD cards, so it’s very long. This reader is beautifully small and low profile, but the connector refused to fit into the port on the amp. I have decided to keep it so I can use it for reading MicroSD cards the rest of the time and not have to pull my current reader from my amp just for that purpose, but the lack of USB-C connector will be a hassle in that case.

Paired this with a memory card and it is working perfectly to record dashcam footage in my Model 3

I love how easy it is to use—just plug it into my laptop or desktop and insert the microSD card, and voila! My files transfer quickly without any lag, saving me precious time during busy workdays or while editing my latest photography project. The durable design ensures it withstands frequent use, making it a reliable tool in my tech arsenal. The dual-slot feature is fantastic, allowing me to use both SD and microSD cards simultaneously, which is perfect for multitasking. Plus, the compact size makes it easy to carry around in my bag, ensuring I always have it on hand for any data transfer needs. However, the reader can sometimes feel a bit flimsy, especially when inserting and removing the cards repeatedly, but it hasn’t caused any issues so far. Additionally, while it’s compatible with a wide range of devices, ensuring a proper connection might require a quick restart on some older systems. Overall, the SanDisk MobileMate USB 3.0 microSD Card Reader is a must-have for anyone dealing with microSD cards regularly. It’s fast, reliable, and incredibly convenient, making data transfers seamless and efficient. A solid 5-star rating for its speed and versatility, with a tiny star lost to its occasional flimsiness.

This little devil works great and is so easy. A must have for mp3 Bluetooth devices for easy file transfers.

I got 3 of these. With all I had the hardest time even getting the reader to detect my MicroSDs, I thought they were broken. Well, They are. I finally got them to detect the cards after a ton of repeated attempts. They were transferring at 160MBps and suddenly, the MicroSDs dismounted. Now the stupid readers won't detect my cards anymore, and my other fast readers can't get more than 87MBps out of these. I could get 180 before with my other readers. One 512 Sandisk Extreme that was untouched by these damn things still reads at 180 with my other readers, and when I swap it to the affected 512 Sandisk Extreme card in the same reader, 87MBps max. I'm LIVID. 2 cards got crippled down to half their speed by touching these terrible readers. I've run tests for hours now trying to figure this out. SO LIVID.

Un producto increíble al lado de las tarjetas micro SD, mucho más práctico y confiable sin batallar en que se detecte.

​Compré este adaptador SanDisk para transferir archivos y funciona de maravilla. Es extremadamente compacto, lo que facilita llevarlo a cualquier lado, y la construcción se siente sólida y duradera. La velocidad de transferencia es consistente y es totalmente "Plug & Play": lo conectas y el equipo lo reconoce al instante sin instalar nada. ​Pros: ​Diseño minimalista: No bloquea otros puertos USB cercanos. ​Velocidad: Aprovecha bien la categoría de la tarjeta micro SD. ​Fiabilidad: No se calienta en exceso ni se desconecta durante el uso. ​Contras: ​Al ser tan pequeño, es fácil perderlo si no se tiene cuidado (recomiendo usar un cordón). ​Veredicto: Una solución perfecta y económica si tu laptop no tiene ranura para tarjetas. Muy recomendado.
