I'm writing to see if anyone has any experience with using/building hubs that can read multiple SD cards at once? I'm trying to explore ways to speed up the manual transfer process of camera trap images from the SD cards to hard drives. With the teams I work with, we often have 50+ camera traps to download data off. Having the potential to read multiple cards at once could potentially really speed up the manual transfer, particulary when there is a need to utilise the cards again in a short timefrime.
There are some commercially available models like the SanDisk Pro-dock 4, or Lexar Professional Workflow series (both with 4 SD card slots), and I recall reading a while back about a project that had built their own and paired it with a download script program that processed the photo metadata (it was on Github but alas I can't find it again despite searching). Most basic SD card readers are for users that may only be working with one or a few cards at once so it makes sense to only require limited read capacity, but for many of us that work with 10s of cards at a time from large camera trap arrays, I thought this could be a helpful advance.
Interested to hear if anyone has worked with a system like this, or knew whether it was possible to design one?
