Yes, ext2.The ext3 and ext4 versions incur a lot of extra read/write overhead for metadata journaling which will impact the overall life of the flash chips. NTFS does the same thing and should be avoided for similar reasons. Just create a top-level directory with permissions 777 and you should be golden. Either that or exFAT which Microsoft designed specifically for removable flash media. exFAT support on linux exists only as a FUSE module so that has its own set of issues. Or just use FAT32. It's portable, it works, and live with the fHuge block sizes. USB flash drives do not support trim. Wear leveling is managed by the on-board controller. -- Rich P. _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
