don't ever use an SD card or solid state drive for a long term archive device.
the way that this technology works is that bits are stored as charges in NAND flash memory.
if you remove the power then over time this charge dissipates, erasing all the data with it.
e.g. if you put all your data on an SSD drive or SD card and put it on a shelf, when you come back to it ten years later there won't be any data on it any more. because the charge would have never been refreshed.
