Hi, |
2 |
A few notes about compact flash, I recently made a research about cflash |
3 |
products. |
4 |
The main safety in compact flash products is in the availability of the wear |
5 |
leveling function (secure mode) |
6 |
low cost cflash do not include this capability , for this reason , you will |
7 |
need to use jffs2 , to allow sector repartition over the disk. |
8 |
|
9 |
However more robust products (sandisk / lexar) include the wear leveling |
10 |
function in the card and it is completely transparent from the user, you use |
11 |
it as a single normal ide disk. |
12 |
Furthermore, lifetime and throuput bandwidth of these products is faster than |
13 |
common camera cflash. |
14 |
|
15 |
If interested in I could give you more details on how to check if your cflash |
16 |
card supports wear leveling . |
17 |
Best Regards |
