Answer to: Acer Iconia Tab W500 SSD/Ram?Acer W500 uses mSATA ssd. Currently you can upgrade it upto 128GB. Regarding RAM, as per C50 processor specification, you can upgrade it upto 4GB but the existing 2GB ram sitting behind the processor and it is soldered to it. I have upgraded my SSD to 64GB, but I did not upgrade the RAM. I really enjoy using this tablet.
