I have one of these storage unit comtrollers, EM09M, but somebody has lost the microSD card.
I cannot seem to find the specifications for the SD card that I would need to buy.
I am lookign at buying a 64GB class10 SDXC card as most of the firmare inages seems to be int he 45GB range.
I think you mistake on the image size. They are nowhere near 45GB. I think you mean 45MB. So a 1GB micro SD card is more than large enough.
