I'm considering using DSL in an embedded data logging product, running from a flash drive. Is there any support for wear leveling in the OS yet?

I'm concerned that after a year or two of 24/7 logging, that I'll wear out the flash. I can aggregate data and log it once every 10 minutes most likely, but that would take more work.

Are there any cache settings that would prevent data writes from occurring too often?

Thanks-

Zeph

Unless you want to log in ramdisk and then perform some backups on a different media, I think it'll wear out pretty soon.

Anyone have any experience with built-in wear leveling on flash products?

try googling for "bdflush"
i remember there was a parameter here delaying the cache write.

(I was trying to speed up file transfers between two fat32 disks then but never succeeded).

Thanks, the first few links that popped up looks promising.
