Ext2 is a good choice as long as you don't want to exchange data with |
| 22 |
Windows (except you can install the ext2 driver on the Windows |
| 23 |
machines). Don't use journalized file systems like Ext3 and Reiserfs |
| 24 |
since their journal causes additional write operations and flash media |
| 25 |
only last a limited number of them. (of course, you could disable |
| 26 |
reiserfs's journal but that's just additional trouble). |

Blocksize for Ext2? As long as you don't transfer many very small files |
| 29 |
(<=3k), stick with the default. |

If you want to continue using FAT, you should create zip or tar |
| 32 |
archives. That way, you can preserve file permissions and don't wast |
| 33 |
space on your stick. |
