Per the Genos Service Manual, internal memory (That would be the User Area.) is a Toshiba 64GByte eMMC device (THGBMGG9T4LBAIR). eMMC stands for embedded Multi Media Card. It's what a lot of the Chromebook type devices use in place of hard drives. That's not quite the same as an SSD, but it is still solid state storage and subject to the same type of catastrophic failure.

Looks like the PA4X is probably your best bet, Steve. Wishing you all the best - whatever you do ! ! !
