As Brahim said, you should know what's going on with your array. To expand on that a little, if you just do a verify sync, then you have no idea what was updated. If it's not updated, you can use the Forensics plugin to see exactly what data is incorrect. Why would you want to know what was updated? If the same drive was constantly having to be updated, you may have a controller, cable or drive which is failing. If the exact same data was constantly being updated, there could also be an issue with a program, your OS, or the parity drive. If different data is constantly being updated, you may even have a memory issue. If that's the cause, every write to your array could be bad data due to memory corruption. Then, it's possible you'd come back here screaming that tRAID was destroying all your data.
Brahim would be better suited to speaking to this part, but I suspect that if updates are constantly necessary, the salt level might need to be adjusted, as well. I'm basing this off the text pop-up for the salt setting, but I'm not certain I fully understand what it's really talking about.
