Which is the best Backup and hard-drive encryption?

[vivek]

I just cant digest this conception of Paid ones being much more efficient and secure. Till now I haven't found any tool which provides better encryption than Truecrypt.

Also, A Paid product doesn't mean its better and more efficient or secure than Free ones?

Actually what you said is absolutely true,I only asked about paid ones since I myself couldn't find anything better than TRUECRYPT.My sincere hope is that the TC developer's should constantly make TC even more better you know like upgrade,since nothing is totally secure.
