What is the cluster size of Jolla's EMMC?

Oh but they do, both for the phone and the tablet the processor is already told. I wouldn't wonder if one developer at Jolla would answer to this, just when they have time :)

No, I think this is a question related to system. In windows, we can re-format disk partition to NTFS in 1024, 2048 or 4096 cluster size. This information is useful when I want to optimize the speed of sqlite ( make the page size same as the cluster size )

Interesting! :) But I wonder how the btrfs block allocation can influence this optimization.

Here is the article: http://www.sqlite.org/cvstrac/wiki?p=PerformanceTuningWindows In the chaper: Three: Page Size can make a difference It mentioned about the relationship between page size of a sqlite database and the cluster size.

@Nieldk: The 512B is only a logical mapping/layer. The internal properties (erase block size, page sizes, segment or allocation unit size) are completely different.
