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

works as advertised

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.

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.

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.

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

Works great

I do a lot of retro games that require moving games from my PC to my handheld and this works

Bought this for my 2026 Yukon Denali XL’s factory video recording system, put it to work right out the package with a PNY High Endurance 512 micro, also new. Vehicle reported no longer recording (after 7 months) , pulled the unit, went to plug it into my PC … it didn’t want to go in, it appears that the Key connectors inside have… well I don’t honestly know, but it flat out stops at the keys. I believe it got hot, melted, stopped working, when I pulled it out it cooled into a position where it won’t plug in. I’m lucky it didn’t fry my 100k trucks electronics.. The Yukon’s port is in the wireless phone charging area that’s virtually got its cover closed all the time. I don’t think this adapter was made for this situation, tho I have had a poor history with SANDISK USB thumb drives also getting very hot and failing is Smart TVs … If you are reading this SANDISK, I will mail it to you for inspection.

Très bien

​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.
