Sadly You are so right!

No, I only run the program for the backup sometimes. It's not a real time backup tool.

I don't know where to look for the onboard cache (it's the value I've set for the pagining file?)
. I' ve a western digital SATA II.

I ask because on Windows, whenever the database is changed the database manager (sqlite3) creates a log file, writes recovery information to it, changes the db, then deleted the log file. It you are using an odd file system then that create/write/delete cycle could be the culprit. If you are using NTFS, it probably isn't the issue.
Another thing to check is whether write-behind caching is turned off on the second drive. Go to the device manager, right-click on the disc in question, choose Properties, and check in the "Policies" section. Turning off write-behind caching would be catastrophic for calibre performance.

I'm using NTSF and the write-behind caching otion is on
