Multi SD Card reader/dock

[ErikReb]

Hey guys! Have you seen micro sd card reader for like 20 cards? I'm looking for one to copy data from multiple sd cards at the same time.

I found this not sure if it works but this is the closest thing I could find.

Perhaps a huge USB hub and then a bunch of USB -> SD converters?

I was kind of surprised but there are actually a LOT of 20 port USB hubs on Amazon.

Thanks for these links. Is USB 3.0 speed enough, i think not.

USB 3.0 can transfer around 300MB/s in tests I've done. Whether or not that is fast enough for you depends on what your needs are.

 

As for your original question... Lexar makes a 3 slot reader (https://www.amazon.com/Lexar-Professional-Three-slot-microSDHC-microSDXC/dp/B012PQM9HI). If you're wanting to offload 20 cards at the same time, you're likely going to have to either make something yourself or have someone custom build you something. Option 3 I guess buying 7 of those lexar units, a USB hub, zip ties, and some 3M double stick tape...
