💨 High-Speed SanDisk Extreme PRO SD UHS-II USB-C Reader - SDDR-409-G46: Unleash Lightning-Fast Transfers Review

I have a fast Lexar UHS-II card (Lexar Professional 2000x 64GB SDXC UHS-II card) and thought I could do better than USB -C to use USB-A reader included with the Lexar card. The sequential read speed was 210 MB/s. The first USB-C reader I tried was obscenely slow, only 82MB/s for [[ASIN: B07DJT5GPT uni USB Type C / Thunderbolt 3 SD Adapter]! This extreme SanDisk reader did the best I could expect from a USB-C connection, which allows for much faster speeds: 267 MB/s. Excellent work!

I tested the SanDisk UHS-II SD card reader on a 2019 16" MacBook Pro and a 2020 11" iPad Pro . In my test, I connect directly to MBP and iPad. As you go through the hub, it slows down. I moved a 2GB file from SD card to iPad Pro and 7 seconds. The card was Sandisk 300MB/sec. I got 220 MB/s with the same card in MBP. It outperformed the Apple SD card adapter by about 10-15 MB/s. So if you're looking for sheer speed and compatibility, buy one or two if you want to read more than 1 card at a time.

I bought one of these last year and it was great. Ultra-fast data transfer speed. I accidentally forgot it at the hotel so I bought another one. It had this weird issue where it streamed at 100% and then just . Break. about 30 seconds. It would then turn back on at full speed and stop. I returned it for another. I looked through FIVE of four different sellers who had the exact same issue. Tested on 3 different computers and iPad. The only reason I went with it was because the first one worked…

Following information from Sandisk customer service. Thank you for contacting SanDisk® Global Customer Support. We really appreciate having you as part of our SanDisk® family. I understand your concerns, so let me let you know that we have tested our Extreme Pro UHS-II Type-C Reader on Windows and Mac platforms only. The reader has not been tested and is not designed for use with a cell phone/smartphone interface, therefore it may or may not work as the reader requires a constant surge of power

Update May 2021: Every two weeks I take a lot of pictures from a V90 UHS-II card to my laptop via the USB-C port. . The supported transfer rate is the worst at 10MB/s! Although this reader claims to support UHS-II cards, which in turn allows for faster transfer speeds. read UHS-I has a higher transfer rate of 30MB/s! No matter how many gigabytes of data is transferred - the built-in UHS-I reader is still better than this reader. No ideas - but it's NOT WORTH the price and demands of a UHS-II…
