I have no information to contrary, but while that assumption makes a lot of sense for a spinning disk, I see no reason to assume this for flash drives and other SSDs. I would think that they may parallelize writes to different parts of the "sector" for efficiency. I don't have any knoladge to base this on, I just don't know if this was ever verified with actual flash drive driver manufacturers. -- ˙uʍop-ǝpısdn sı ɹoʇıuoɯ ɹnoʎ 'sıɥʇ pɐǝɹ uɐɔ noʎ ɟı _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
