I am wondering about the storage needed for the operating system and the remaining available storage which can actually be used for ebooks.

You can see the total onboard storage under "Settings/Device information/Onboard storage", e.g. 8 GB for the Kobo Clara HD. There you can also see the remaining free storage, e.g. 2.2 GB. Under "Settings/Manage downloads/Imported items" you can see the number of items (ebooks), e.g. 2956 imported items, and the related storage size, e.g. 3.26 GB. In this example the operating system has a size of 8 GB (total) - 2.2 GB (free space) - 3.26 GB (used space) = 2.54 GB.

I find that with the Kobo Clara HD (8 GB) the operating system takes 2.54 GB, with the Kobo Clara 2E (16 GB) it takes 5.66 GB and with the Kobo Libra 2 (32 GB) it takes 8.31 GB. Of course both the Clara2E and the Libra 2 can be used to listen to audiobooks (this functionality will increase the OS size) but I wonder if that really explains the drastic increases in size.

Do you find similar numbers with your devices?
