I've got a metric fuckton of microsd cards that may or may not have important data on them, and I'm trying to figure out an easy way to rip all their contents to an HDD or similar so that I can more easily store the data, search it, etc.

Is there any special purpose device or possibly Linux software to make this task easier? I am envisioning a device with a bunch of SD card slots or USB ports that would just immediately download everything from the card into a hard drive as soon as it's plugged in, so that I could just power through a pile of the things without having to manually copy things over for each device. Support for other storage formats (IDE, SATA) would be great too but not strictly necessary. Anyone have any ideas?
