Hi, JÃrgen,

the default block size in jffs2 is 4kB. But with FTP, packets have at most 1448 B payload.
If I put a file of 12kB, is the file then put in 3 nodes if 4kB, or is it put in 9 nodes (because FTP uses 9 packets) ?

Besides what JÃrgen wrote, it also depends on how your FTP program buffers, which parts it writes in a single write call, and when it syncs/flushes buffers.

It still doesn't matter because the file system and/or JFFS2 will be buffering it to suit their needs.
