SD Card Reader, 2-in-1 USB C Memory Card Reader for Digital Camera SD Card Viewer with Dual Slot for SDXC, SDHC, SD, MMC, RS-MMC, Micro SDXC,MicroSD, Micro SDHC Card, and UHS-I Cards

Nice compact size. Easy to use. Works perfectly.

I’ve put this little Anker reader through absolute abuse flashing Raspberry Pi OS images on my Windows laptop, pulling video off microSD cards, moving firmware, backing up configs, you name it. It lives in my backpack and gets used constantly, and it hasn’t missed a beat once. Transfer speeds are fast and consistent. No random disconnects, no “device not recognized,” no cheap plastic heat-up nonsense. The dual SD + microSD slot setup is perfect when you’re bouncing between Pi projects and other devices. Plug it in, drop your image, and you’re flashing a fresh OS in seconds. What I really love is that it’s built like a tank for something this small. Solid metal, no flex, no cheap feel. It just works every single time which is exactly what you want when you’re doing quick field updates or emergency card reads. If you do anything with Raspberry Pi, SDR, drones, cameras, or honestly just want a reliable SD reader that won’t quit… this is the one. Anker knocked it out of the park.

Works great. Easy and straight forward to use. Was able to use this to get family pictures from my camera’s SD card onto my MacBook!

Very compact! Works as expected. Much faster than connecting the go-pro itself to the USB for copying files off. I should have bought one of these years ago.

The official SD card specification (for UHS-1) tops out at around 100MB/s (before overhead, etc so you usually see more like 95). Sandisk, Samsung and others that release UHS-1 cards (which is the most common by far today) that claim reads and/or writes in excess of this have re-used the "double data rate" mode of older SD specifications at lower clock speeds and applied it to the maximum 208Mhz SDR mode to transfer up to twice as much data as the normal maximum in the official specification. That modification is fairly common these days (since UHS-2 didn't really take off since it needs more pins and has other issues) but you never know unless the card reader manufacturer tells you they support these "non-standard" (but nonetheless desirable) "extra" speeds. So: this card reader worked fine, didn't have any issues, and I got the maximum speed (of about 95 MiB/s reads, with writes being a bit slower: 83 MiB/s or so). It was able to read the cards I tested between 32GB and 1TB (well, "1TB" because it was a TeamGroup that was short 10GB, even if you used base 10 and not power of 2, ie TB instead of TiB). Like all readers of this type that I've had/tested, it was capable of simultaneously accessing two cards at once (one full-sized and one micro) but you get less than half speed on each (ie: more like 40 MiB/s + 40 MiB/s when both are reading, not either 95 + 95 or even 47.5 +47.5). I'm guessing most or all of these have a single SD controller and it switches between the two (with some overhead). If it had supported the higher (non-standard) speeds I probably would have kept it but I already got a cheaper one that does support them as well as both USB-C and A (where this one only supports C). Bottom line: this was well made, smaller than some, and follows the SD card specification, but for "just" that, there are less expensive options.

This works well to read my GO Pro mini SD card on my MacBook Air. Price was right, and it runs smoothly.

My waterproof camera doesn't have wifi so this reader works great for sending pics from the memory card to my iphone. Works easily and quickly

The SD card worked perfectly with no issues, fast downloading speed only downside is it heats a bit when downloading lots of videos 12 at the same time.
