SanDisk Extreme PRO SD UHS-II USB-C Reader - SDDR-409-G46

Works great. Its the fastest data transfer cord I own. Videos that used to take me 10-15 minutes to transfer now take 30 seconds max. Super useful for a quick transfer. Also super high quality material. Not cheaply made or cheap feeling at all. Highly recommend after all the research into these things I did. By far the winner.

I've noticed that some USB-C SD readers (I have a bunch) don't like to stay connected to my primary PC, but this one never seems to drop connection and seems to maintain fast and uncorrupted data streams. I move a lot of data to and from SD cards, and this has really been an excellent buy -- I do, however, wish it had both a regular SD and micro SD slot -- but that does not prevent a 5 star rating.

The SanDisk Extreme PRO SD UHS-II USB-C Reader, model SDDR-409-G46, is an absolute game-changer for transferring data quickly and efficiently. As someone who relies on fast and reliable data transfers, this reader has exceeded all my expectations. Its USB-C connectivity ensures lightning-fast transfer speeds, allowing me to offload large files in a fraction of the time compared to other readers. The UHS-II compatibility means it's optimized for high-speed SD cards, perfect for handling 4K video footage or RAW image files with ease. Plus, its compact and durable design makes it perfect for on-the-go use, whether I'm in the studio or out in the field. Whether I'm a professional photographer, videographer, or simply a tech enthusiast, this reader is a must-have accessory. Five stars all the way for the SanDisk Extreme PRO SD UHS-II USB-C Reader!

Works snd seems faster than built in socket. I have not software to measure data flow.

Works great to download to my android phone

It looks great and works well but it doesn’t run UHS-1 cards at max speed. Haven’t tested UHS-2 so don’t know about those.

Insane speed upgrade, from 15-25 minutes getting off the camera to 1-3 minutes with this separate card reader. To go with this, I got the Lexar 256GB microSDXC UHS-II card. I record roller hockey games while I referee and play and upload to Youtube, can find some searching for Peoria Sportsplex. I use a Xiaomi Yi 4k camera set to 1080p60fps. About 45 minutes of video is like 15-20GB depending on the medium or high quality setting. I was using a 128GB SanDISK Extreme PLUS V30 microsd. I was simply connecting to my computer with the camera hooked up to USB. It would take about 15-25 minutes to get the videos off of my camera. Now I take the microsd out of the camera, plug it into the reader and it takes 1-3 minutes to get the videos onto my PC. I wish I didn't wait this long to upgrade. Extreme time saver. I also wish they didn't make it so hard to actually find UHS-II microsd cards.

I got this for a Mac Mini M4 and a iPad Pro. After figuring it out, my wife copied photos and videos to it much quicker than with a USB-A. It is new so longevity is an unknown.

Faz pouco menos de um ano que uso esse leitor de cartões. Resistente, feito com bons materiais, realiza transferências de forma rápida e sem contratempos. Uso constantemente e nunca apresentou falha.

Purchased item for my Apple laptop for photos editing SD cards. Reliable and easy to carry around plus storage

Livraison rapide, produit bien emballé et conforme à la commande. Beaucoup plus rapide que les "sous-marques" qui plafonnent à 84 mo/s. Avec celui là on dépasse les 200 Mo/s si la carte SD le permet ainsi que le câble et l'ordi (ou tablette ou téléphone). Et plus fiable : une marque d'entrée de gamme m'a lâché au bout d'une 20ène d'utilisation ! Testé branché directement à un téléphone Android (Samsung Note 10) et tablette Samsung Tab A : 100% fonctionnel ;) Remarque : ne prend que les SD, pas les micro-SD (sauf si mise dans un adaptateur SD/microSD)
