a lot of operations will run from ram (cache) anyway, the devices have plenty of ram (for ebook reader) which is rarely ever actually used.
There are cards that may do fast sequential (necessary for high resolution photos or videos) but still have abysmal 4K performance. Like way below HDD level: 0.05MB/s or less. The good ones tend to perform at HDD level as far as small block goes.

Granted, I can be a bit exacting as I need my cards to deal well with apps and full Linux OS (well, Raspberry Pi and before that, Nook Color and Android devices). You may be right that even 0.05MB/s suffices for the Kobo. After previous experience with constant crashing though, I wouldn't take a chance on a card/flash drive that needs to run an OS when the price difference is usually just a couple of bucks.
