[GRHE]

First time poster here. Intending to purchase an eReader shortly (Black Friday, probably). Looking at recent models it will either be 11th gen Paperwhite or Kobo Libra 2 - really, the only two brands available in South Africa, both orderable through Amazon. I really prefer the Kobo Libra 2 (buttons) of the two but have some concern as to the reliability of the internal micro sd card it uses.

My other two hobbies are photography and playing around with single board computers - both make extensive use of micro SD cards. I have had expensive class 10 SD cards fail after minimal use on rare occasions which is a nuisance but does not render a camera or SBC dead. However a failure of the sd card in the Kobo would kill it from my understanding - am I wrong?.

I am equally unsure whether the sd card in the Kobo is only used for book storage or whether it is also used to store the Linux operating system. I guess what I am asking long time Kobo users, have there been issues of card failure on the device(s)? Is it a valid concern or shouldn’t I be worried? Having a dead device would cost me more than the device itself to send it back to Europe or Canada for repair from South Africa. Thanks.
