Then you need backup power. There is no other solution. |

As others have indicated, the particular type of flash "drive" is |
| 10 |
very significant, because the electronics between CPU and flash chip |
| 11 |
is obviously in control of writing and caching. If you are using |
| 12 |
anything other than an mtd interface then you have much worse odds of |
| 13 |
being able to survive power loss. |

RAID does nothing. |

Without mtd you are in such a bad situation that it almost doesn't |
| 32 |
matter what you do on top of the block device as long as it's |
| 33 |
journalled. |
| 34 |
|
| 35 |
Of course if all partitions are mounted ro then there is no problem. |
| 36 |
|
| 37 |
If you need write then make sure to use mtd hardware and jffs2 or such. |
