Accessible Internal uSD card
Here are some pictures of a hatch I made that allows access to the internal uSD card of my AuraHD. It is made easy by the adhesive backed foam rubber cussion/gripping surface I applied, see post: https://www.mobileread.com/forums/sho...d.php?t=214575

The opening process is a matter of using something of about the thickness and rigidness of your thumbnail, to separate the slots and bumps. You just have to work it into the crack between the Bezel and the case and then work your way around the case slowly lifting the Bezel as you go to both move the slots away from the bumps and lift the two sided tape that is on the Bezel off the screen.

There has been a lot of discussion in these forums over the benefits of different classes of SD cards. It's been shown that the class of the card is not the key factor in performance.

So what is? The brand?
Hopefully not the size. With koreader finally being able to process scanned books in pdf my library will need the space. |

Try searching on "Small block writes".

Before you say it's just DNSB saying this, try searching via Google for people doing similar experiments on different devices. |

My guess is that ebooks, even large ones, are accessed in small, a page or two at a time, increments. So I feel that DNSB has a valid point and Class 4 cards might be preferable over the Class 10 cards. (even if most class 10 cards are really class 6) I have not looked into the new classification system very much but I remember it as being touted as more reflective of performance in relation to multimedia files. All in all, I doubt there is any great difference, but see no reason not the use the Class 4 cards for ereaders and the Class 10 for tablets. There is that most consumers would not be aware of this distinction and "(4)" is less than "(10)"; the class 4 cards should be cheaper. As you can see I would have no problem changing mine if I noticed any problem. To answer your question, they all will work in the Aura it is a matter of a possible slight difference in performance.

While your guess makes sense from the perspective of pages in a book, it is also worth remembering that ePubs are compressed. It is far more likely that ePubs are being accessed a file at a time (from the perspective of the container, not the file system) than in smaller chunks. I would imagine that the filesystem plays a role to, since they frequently cache data in order to avoid less efficient reads.

@DNSB: Thanks for sharing all that. I should probably add some links to the SD discussions ot the tips thread.
